  51. [04:05:19] <Sonicadvance1> :|
  52. [04:05:38] <Sonicadvance1> Is mmap memory access different on Panda than x86?
  53. [04:10:22] <_av500_> why?
  54. [04:13:49] <prpplague> Sonicadvance1: have a look at devmem2 - http://www.elinux.org/images/a/aa/Devmem2.c
  55. [04:14:14] * Vikas_Joshi (~uda086869@nat/ti/x-eapksycxdgqmbgrb) Quit (Remote host closed the connection)
  56. [04:14:45] <Sonicadvance1> _av500_, code not acting quite as I expect

  58. [04:22:52] * wardred (~wardred@75-142-253-144.dhcp.reno.nv.charter.com) has joined #pandaboard
  59. [04:33:46] <av500> prpplague: devmem2????
  60. [04:33:49] <av500> Sonicadvance1: explain
  61. [04:34:45] <prpplague> av500: as an example of using mmap from user space
  62. [04:35:08] <av500> prpplague: how do you use mmap from kernel space? :)
  63. [04:35:11] <ds2> devmem2 == the greatest security threat
  64. [04:35:21] <av500> security?
  65. [04:35:41] <ds2> with a carefully phrased set of arguements, one can destory hardware with the stroke of a carridge return
  66. [04:37:14] <prpplague> av500: you don't but i wanted to be clear as to the purpose of the devmem2 example
  67. [04:44:00] * wardred (~wardred@75-142-253-144.dhcp.reno.nv.charter.com) Quit (Ping timeout: 250 seconds)
  68. [04:45:40] <Sonicadvance1> av500, very complicated project, not entirely sure why it's failing atm actually >>
  69. [04:46:12] <Sonicadvance1> Can only think of memory access differences
  70. [04:46:49] <prpplague> Sonicadvance1: mmap really shouldn't be used other than for some serious debugging, other methods are available
  71. [04:47:55] <Sonicadvance1> prpplague, porting a project that uses mmap in a similar way to the Windows function CreateFileMapping and it's sibling functions
  72. [04:48:29] <prpplague> hehe, theres a problem from the very start, hehe
  73. [04:50:05] <prpplague> Sonicadvance1: if you are trying to use a specific area of sdram for your application, you will need to set aside that area so that linux kernel knows not to use it
  74. [04:50:52] <prpplague> Sonicadvance1: i assume you are wanting to deal with ram? is that correct?
  75. [04:51:06] <av500> prpplague: what???
  76. [04:51:13] <av500> prpplague: what is wrong with mmap?
  77. [04:51:16] <Sonicadvance1> Of course :|
  78. [04:51:42] <Sonicadvance1> mmap(0, size, PROT_READ | PROT_WRITE, MAP_SHARED, fd, offset);
  79. [04:51:59] <Sonicadvance1> and mmap(0, 0x31000000, PROT_READ | PROT_WRITE, MAP_ANON | MAP_SHARED, -1, 0);
  80. [04:52:35] <Sonicadvance1> first using some temp space on a temp file in /tmp
  81. [04:52:49] <av500> -1?
  82. [04:53:41] <prpplague> Sonicadvance1: uh what?
  83. [04:53:48] <prpplague> Sonicadvance1: none of that makes sense
  84. [04:53:57] <Sonicadvance1> some implementations require fd to be -1 if MAP_ANONYMOUS (or MAP_ANON) is specified, and portable applications should ensure this
  85. [04:53:58] <av500> CreateFileMapping looks just like mmap....
  86. [04:54:41] <av500> Sonicadvance1: right
  87. [04:55:00] <av500> basically you want to create shared memory?
  88. [04:55:39] <Sonicadvance1> Indeed. This has been tested to work on x86 just fine :|
  89. [04:55:55] <Sonicadvance1> and I had it working in a ARM VM at one time as well
  90. [04:56:29] <av500> Sonicadvance1: but you are aware that you are trying to map 784MB?
  91. [04:56:36] <av500> out of 1GB total mem
  92. [04:56:39] <Sonicadvance1> right
  93. [04:56:41] <av500> or maybe less
  94. [04:56:50] <av500> right?
  95. [04:56:55] <av500> does it work for less?
  96. [04:57:10] <Sonicadvance1> would fail with less o_o
  97. [04:57:16] <Sonicadvance1> the program that is
  98. [04:57:28] <av500> but you expext linux to swap the mmaped region to disk or what?
  99. [04:57:46] <av500> Sonicadvance1: well, then fix you program
  100. [04:57:54] <av500> or solder more RAM
  101. [04:58:32] <prpplague> Sonicadvance1: what are you setting as the offset?
  102. [05:02:29] <TheSeven> btw, does anyone have an idea what the recent findings here could mean? https://bugs.launchpad.net/linux-linaro/+bug/709245
  103. [05:02:36] <prpplague> Sonicadvance1: if you are setting it to 0 then it will map to the base of the all physical register space
  104. [05:03:09] <Sonicadvance1> prpplague, Couple, 0x2000000, 0x40000, 0x2000000
  105. [05:04:24] <Sonicadvance1> + couple mirrors
  106. [05:04:26] <av500> prpplague: no
  107. [05:04:59] <av500> prpplague: for MAP_ANON fd and ofs are ignored
  108. [05:05:11] <prpplague> av500: ahh right
  109. [05:05:31] <Sonicadvance1> We don't use offset for the mmap'ed space with MAP_ANON
  110. [05:05:40] <prpplague> av500: i never use those options
  111. [05:05:41] <Sonicadvance1> there are multiple spaces mapped here ;p
  112. [05:06:39] * skorgon (~skorgon@unaffiliated/skorgon) has joined #pandaboard
  113. [05:07:43] <prpplague> Sonicadvance1: what is this program suppose to do?
  114. [05:08:31] <Sonicadvance1> http://dolphin-emu.googlecode.com
  115. [05:09:00] <Sonicadvance1> trying to figure out what was so different between the Qemu ARM VM I ran vs pandaboard :/
  116. [05:10:40] <prpplague> Sonicadvance1: got a link to the section of code you are working with?
  117. [05:12:21] <Sonicadvance1> Basically the entire Interpreter CPU core >>
  118. [05:12:22] <av500> Sonicadvance1: what about that tmp file?
  119. [05:12:33] <av500> fd = open(ram_temp_file, O_RDWR | O_CREAT, mode);
  120. [05:12:52] <av500> return mmap(base, size, PROT_READ | PROT_WRITE, MAP_SHARED | MAP_FIXED, fd, offset);
  121. [05:13:19] <av500> if you only use that mem, linux will keep it in page cache anyway
  122. [05:13:28] <av500> if not, you are out of mem anyway
  123. [05:17:14] <Sonicadvance1> Well, it uses more. Most RAM it uses is virtual
  124. [05:17:35] <Sonicadvance1> I think usually it caps at ~350MB of real RAM
  125. [05:18:44] <Sonicadvance1> Running the program, I'm using 442MB/665.9MB
  126. [05:19:06] <Sonicadvance1> Using Ubuntu 10.10 due to disk speed failure in 11.04 >>
  127. [05:21:22] <av500> Sonicadvance1: so it works?
  128. [05:21:48] <Sonicadvance1> eeehhh, it runs but is trying to HLE everything for some reason >>
  129. [05:22:13] <Sonicadvance1> which is set via some bit or something? I can't remember
  130. [05:22:31] <av500> HLE?
  131. [05:23:19] <Sonicadvance1> High level Emulation
  132. [05:24:02] <Sonicadvance1> It's what led me to believe that somehow memory access is slightly wonky
  133. [05:27:10] <Sonicadvance1> Although maybe Panda is just slower than a QEmu ARM VM on a core 2 duo at 2.3Ghz :|
  134. [05:31:03] * hardwalker (~hardwalke@122-117-115-146.HINET-IP.hinet.net) has joined #pandaboard
  135. [05:38:33] <TheSeven> hm, what's the difference between sudo ping -q -i.0099 localhost and sudo ping -q -i.0100 localhost?
  136. [05:38:58] <av500> .0001
  137. [05:39:18] <TheSeven> the first one causes a full core of CPU load, the latter one just 1%
  138. [05:39:43] <TheSeven> the first one increases USB throughput by a factor of 5, the latter one just by a factor of 2
  139. [05:40:14] <TheSeven> now what the hell is going on there?
  140. [05:41:13] * fanghuaqi (~fanghuaqi@2001:c08:3700:ffff::1e:1c18) has joined #pandaboard
  141. [05:41:18] <Sonicadvance1> at < 1/10second it requires high precision CPU work?
  142. [05:41:21] * fanghuaqi (~fanghuaqi@2001:c08:3700:ffff::1e:1c18) has left #pandaboard
  143. [05:43:24] <TheSeven> the .0099 one sends roughly twice as many packets as the .0100 one
  144. [05:45:59] <Sonicadvance1> low precision vs high precision?
  145. [05:46:45] <TheSeven> also the packet count that the .0100 one produces is way too low
  146. [05:47:17] <TheSeven> on x86, the packet counts seem to always be accurate, but .0200 uses 1% and .0100 uses 100% CPU
  147. [05:47:43] <prpplague> TheSeven: the direction the debugging is going is that this is a thread issue, i suspect that the .0099 is just under the thread timing
  148. [05:48:00] <prpplague> TheSeven: linaro folks and fedora folks are working on debugging this
  149. [05:48:12] <prpplague> TheSeven: it doesn't appear to be panda or omap4 specific
  150. [05:48:25] <prpplague> TheSeven: it has been recreated on the snowball and on a tegra platform
  151. [05:49:22] <TheSeven> on x86 it's actually .0101 vs. .0100, which also auses a 30% jump in packet numbers and 100x jump in CPU usage
  152. [05:49:49] <TheSeven> prpplague: any idea how this is related to the USB slowness issues?
  153. [05:50:12] <TheSeven> a 100% CPU using ping seems to be a surefire way to improve USB speeds a lot
  154. [05:50:45] <TheSeven> pinging the panda from some other machine with .0001 interval seems to help it as well
  155. [05:50:46] <prpplague> TheSeven: like i said, right now the line of debugging is looking at some of the threads for usb operations
  156. [05:57:02] <TheSeven> pinging it from a different machine with -i.01 already results in a 3x speedup, -i.001 results in a 5x speedup
  157. [05:59:26] <TheSeven> .01 causes 1% cpu load, .001 causes 5% cpu load
  158. [05:59:56] * ScriptFanix (vincent@Hanaman.riquer.fr) Quit (Ping timeout: 260 seconds)
  159. [06:00:39] <mturquette> prpplague: is CPUfreq enabled when you see this?
  160. [06:01:12] <TheSeven> anything I could try to help debugging this?
  161. [06:01:16] <TheSeven> nohlt didn't have any effect
  162. [06:01:40] * ScriptFanix (vincent@Hanaman.riquer.fr) has joined #pandaboard
  163. [06:01:48] <mturquette> i'd be curious if this same behavior was seen with performance CPUfreq governor.
  164. [06:02:00] <mturquette> (versus some scaling governor like ondemand)
  165. [06:02:24] <mturquette> i've observed that USB, WLAN and MMC throughput are all greatly affected by ARM frequency.
  166. [06:03:04] * ssvb (~ssvb@a88-114-220-213.elisa-laajakaista.fi) Quit (Quit: Leaving)
  167. [06:03:29] <koen> mturquette: ARM or L3?
  168. [06:05:51] <prpplague> mturquette: i haven;t been following it too closely
  169. [06:06:26] <prpplague> mturquette: https://bugs.launchpad.net/linux-linaro/+bug/709245
  170. [06:06:39] <TheSeven> mturquette: how would I switch the governor? seems like the default kenrel is somewhat hardwired to ondemand
  171. [06:06:47] <TheSeven> kernel*
  172. [06:07:15] <mturquette> TheSeven: echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_governor
  173. [06:07:47] * gsedej_work (~gasper@seraph.uni-mb.si) has joined #pandaboard
  174. [06:07:51] <Sonicadvance1> any news on getting SD card speeds faster? Compiling is terrible :/
  175. [06:07:54] <TheSeven> there's no cpufreq in cpu, that's why i'm asking
  176. [06:08:02] <TheSeven> er, in cpu??
  177. [06:08:03] <mturquette> koen: ARM. You're right to think L3. I've seen all of the drivers I've mentioned hold bus tput constraints and still suck. Then ARM frequency goes up and *bam* good numbers.
  178. [06:08:05] <TheSeven> cpu0*
  179. [06:08:35] <mturquette> TheSeven: then how do you know that it is hardwired to ondemand?
  180. [06:08:56] <koen> mturquette: I'm so used to omap3 where L3 gets outperformed by a piece of wet string
  181. [06:09:38] <mturquette> optimized wet string.
  182. [06:09:43] <prpplague> hehe
  183. [06:09:43] * mturquette goes to bed.

  190. [06:14:01] * skorgon (~skorgon@unaffiliated/skorgon) Quit (Ping timeout: 246 seconds)
  191. [06:14:15] <TheSeven> mturquette: hm, seems like cpufreq isn't supported at all with this kernel and freqeuency is fixed at 1GHz... so that can't be the culprit either
  192. [06:14:22] <prpplague> in 10 years of doing arm dev under linux, i think i've done native compile maybe 5 times
  193. [06:14:38] <prpplague> TheSeven: not nessarily true
  194. [06:14:54] <prpplague> TheSeven: what kernel are you using? the old 2.6.35 ubuntu kernel?

  196. [06:15:14] <TheSeven> Linux panda 2.6.38-1208-omap4 #11-Ubuntu SMP PREEMPT Fri Apr 15 16:34:35 UTC 2011 armv7l armv7l armv7l GNU/Linux
  197. [06:15:45] <prpplague> hmm, that should have had the scaling
  198. [06:15:56] <prpplague> TheSeven: might try the 3.0 kernel and see how that performs
  199. [06:15:57] <Sonicadvance1> koen, Thinking about setting up a shared folder and just compiling over the network >>
  200. [06:16:03] <TheSeven> CONFIG_ARCH_HAS_CPUFREQ=y
  201. [06:16:03] <TheSeven> CONFIG_ARCH_HAS_CPU_IDLE_WAIT=y
  202. [06:16:09] <TheSeven> but nothing in /sys
  203. [06:16:27] <TheSeven> prpplague: where can I find suitable 3.0 builds?
  204. [06:16:52] <prpplague> TheSeven: on your harddrive after you download the source and compile it
  205. [06:17:33] <prpplague> Sonicadvance1: why not just cross-compile?
  206. [06:17:56] <Sonicadvance1> prpplague, sounds like a pain

  211. [06:19:04] <Sonicadvance1> the six minutes of recompile time to test against something that I'm not quite sure how is failing is a bit annoying
  212. [06:20:31] <prpplague> Sonicadvance1: cross compiling is pretty easy to setup
  213. [06:22:43] <prpplague> Sonicadvance1: most people will setup a nfs share for your work area between your host pc and the target, cross compile on the host pc and drop the resulting binary over into the nfs share
  214. [06:22:55] <prpplague> Sonicadvance1: then you just execute it on the target

  221. [06:27:37] <TheSeven> compiling linux myself isn't really fun, especially as I currently don't have the tools set up
  222. [06:27:49] <prpplague> TheSeven: i am sure someone somewhere has some posted
  223. [06:29:05] <TheSeven> but if cross compiling is easy to set up in your opinion, you can certainly point me to some howto?

  231. [06:34:20] <TheSeven> so i should use 2010q1 for 3.0 builds?
  232. [06:34:23] <prpplague> TheSeven: those are easy to install and are good for newbies

  337. [10:19:23] <TheSeven> smspillaz: what did you do to it? this thing doesn't exactly seem to be easy to fry
  338. [10:19:43] <TheSeven> lnxy: nah, it was just a broken kernel
  339. [10:19:49] <TheSeven> after picking the right source, it worked
  340. [10:21:34] <smspillaz> TheSeven: dunno, was installing ubuntu, screen blanked for an extended period, hit pwron_reset and it died pretty much
  341. [10:21:53] <smspillaz> though I noticed that in order to get it to boot I had to wiggle the sd card around a bit
  342. [10:22:26] <TheSeven> so even after a full powerdown it doesn't come up again?
  343. [10:22:35] <smspillaz> nope
  344. [10:22:38] <smspillaz> even with the sd card removed
  345. [10:22:40] <TheSeven> how are you powering it?
  346. [10:22:51] <smspillaz> 5v ac adapter
  347. [10:23:00] <smspillaz> though, I tried usb as well and got nothing there

  350. [10:23:42] <smspillaz> with a voltmeter?

  364. [10:40:53] <TheSeven> smspillaz: have you even done anything nasty to it?
  365. [10:40:58] <smspillaz> TheSeven: nope
  366. [10:41:15] <smspillaz> TheSeven: I've removed and inserted the sd card quite a lot though
  367. [10:43:32] <TheSeven> smspillaz: has this board been disconnected from power for a couple of minutes after it died?
  368. [10:44:59] <smspillaz> TheSeven: yeah
  369. [10:45:02] <smspillaz> still no luck
  370. [10:45:16] <TheSeven> another thing you could try would be shorting pin 11 or 12 to pin 7 (gnd) on expansion connector B
  371. [10:45:24] <TheSeven> that are the power/reset "buttons"
  372. [10:45:36] <smspillaz> TheSeven: I'll give that a try
  373. [10:46:08] <smspillaz> TheSeven: I know at least that my power supply makes a kind of high pitched sound like a circuit is actually being formed
  374. [10:46:20] <smspillaz> (like does during normal operation)
  375. [10:47:06] <TheSeven> the pin next to the tiwi module is pin 2
  376. [10:47:56] <TheSeven> so you'd need to short one of the pins in the 4th column counting from the tiwi module to one in the 6th column
  377. [10:48:58] <TheSeven> if you have the tiwi on the left, the top pin of the lower connector in the 6th column is reset, the bottom pin is power
  378. [10:49:53] <smspillaz> tiwi being the wifi module ?
  379. [10:50:16] <TheSeven> yeah, being marked "TiWi01-R2" or something
  380. [10:52:00] <smspillaz> okay

  382. [10:52:20] <smspillaz> shorting pin 7, 8, 9, 10, 11, 12 ?
  383. [10:52:34] <TheSeven> hm?
  384. [10:52:40] <TheSeven> 7/8 (4th column) is gnd
  385. [10:52:58] <TheSeven> 11 is reset, 12 is power
  386. [10:52:58] <smspillaz> (hm?)
  387. [10:53:02] <smspillaz> oh ok
  388. [10:53:23] <smspillaz> so we only want to short 12
  389. [10:53:26] <TheSeven> so you would short 11 to 7/8 or 12 to 7/8
  390. [10:53:37] <smspillaz> ah ok
  391. [10:53:54] <smspillaz> so sticking a paper clip between 12 and 7 for example
  392. [10:54:14] <TheSeven> yeah, but make sure that you don't accidentally touch any other pin with it
  393. [10:54:22] <Sonicadvance1> Maybe I should run this GC emulator in Dual Core mode. FPS: 0 - VPS: 0 - Speed: 0
  394. [10:54:22] <TheSeven> and better count pin numbers twice :)

  397. [10:55:24] <smspillaz> TheSeven: so that pin marked J6 is pin 1 right?
  398. [10:55:37] <TheSeven> exactly
  399. [10:55:39] <smspillaz> and the one next to it (towards the tiwi) is pin 2
  400. [10:55:40] <smspillaz> ok
  401. [10:55:54] <smspillaz> and the one directly below pin 1 is pin2
  402. [10:55:56] <smspillaz> right?
  403. [10:55:59] <TheSeven> yes
  404. [10:56:02] <smspillaz> err
  405. [10:56:06] <smspillaz> ping3
  406. [10:56:09] <smspillaz> pin3
  407. [10:56:18] <smspillaz> so something like
  408. [10:56:22] <TheSeven> pin 3 is to the right of pin 1
  409. [10:56:30] <TheSeven> pins 1-8 are USB ports btw :)
  410. [10:56:46] <smspillaz> ah
  411. [10:56:48] <smspillaz> hang on
  412. [10:56:55] <smspillaz> so it goes
  413. [10:57:06] <smspillaz> tiwi | pin 2 | pin 1 | j6
  414. [10:57:10] <smspillaz> then
  415. [10:57:25] <smspillaz> | pin 4 | pin 3 |
  416. [10:57:26] <smspillaz> right ?
  417. [10:57:29] <TheSeven> yep
  418. [10:57:36] <smspillaz> so 3 is below 1
  419. [10:57:48] <TheSeven> if you have the connector on the right side of the board, yes
  420. [10:57:58] <smspillaz> yeah
  421. [10:58:01] <TheSeven> (ethernet etc. facing towards you)
  422. [10:58:18] <TheSeven> or facing downwards, depending on your point of view
  423. [10:58:23] <smspillaz> yeah
  424. [10:58:28] <smspillaz> and I want to go from 7 to 11
  425. [10:58:35] <smspillaz> err
  426. [10:58:38] <smspillaz> 7 to 12
  427. [10:58:50] <TheSeven> the first thing I did when I got my board was soldering headers into these ports and connecting two little pushbuttons to certain pins :)

  429. [10:59:04] <TheSeven> yeah, or 8 to 12, doesn't matter
  430. [10:59:44] <smspillaz> ok
  431. [10:59:46] <smspillaz> I've got 7 to 12
  432. [10:59:51] <smspillaz> and now just ... power in ?
  433. [11:00:18] <TheSeven> first power it, then connect those pins for a second
  434. [11:00:25] <TheSeven> behaves like a pc's power button
  435. [11:00:52] <TheSeven> short "press" does power on or signal an event to the OS, 8 seconds press does a hard power off

  438. [11:03:31] <smspillaz> TheSeven: hmm, nothing
  439. [11:04:33] <TheSeven> yeah, disconnecting power for a couple of seconds would usually reset the pmic anyway

  441. [11:04:57] <TheSeven> so now you'll probably need a voltmeter...
  442. [11:05:13] <smspillaz> yeah
  443. [11:05:20] <student_> can anyone help me out in telling me where are the drivers files related to audio in panda (i.e. twl6040)
  444. [11:05:31] <smspillaz> TheSeven: alright, I'll give that a try tomorrow
  445. [11:05:38] <TheSeven> or you could keep those pins connected for ~10 seconds with 5v connected and check if your PSU suddenly gets silent :)

  449. [11:07:02] <TheSeven> oops, mistyped the number
  450. [11:07:10] <TheSeven> this one looks better: /sound/soc/codecs/twl6040.c

  452. [11:07:50] <smspillaz> TheSeven: yeah, the power supply goes silent after 10 sec
  453. [11:07:56] <smspillaz> bbiab
  454. [11:07:56] <student_> TheSeven : thanks a lot, but there are few more files in sound/soc/codecs/twl6040*.c , can u tell me what those files deal with?
  455. [11:08:17] <TheSeven> smspillaz: so the voltage regulators are apparently still working
  456. [11:09:01] <LetoThe2nd> student_: there's exactly one.
  457. [11:09:39] * jojobest (~joffrey@192.93.161.12) Quit (Ping timeout: 255 seconds)
  458. [11:10:15] <student_> LetoThe2nd : yes theres a file sound/soc/codecs/twl6040*.c so what does this deal with, because i found 2 more files in drivers/mfd/twl6040*.c
  459. [11:10:41] <LetoThe2nd> student_: mfd stands for multiple function device. go figure. :-)
  460. [11:10:59] <LetoThe2nd> student_: besides, why not just open the files and see what they do? ;-)
  461. [11:11:35] <TheSeven> student_: the mfd ones are twl6030
  462. [11:11:48] <LetoThe2nd> (which is the power companion, IIRC)
  463. [11:12:25] <TheSeven> yes, it is
  464. [11:13:07] <TheSeven> smspillaz: so everything up to the twl6030 seems to be working...
  465. [11:14:03] <student_> TheSeven : in mfd also we have twl6040 files, Yes i tried to figure out the difference between these two files, but the problem is that both the files have module_init(twl6040_codec_init)
  466. [11:14:15] <student_> TheSeven : so i am not able to understand which actually is the driver file
  467. [11:14:46] <LetoThe2nd> student_: your tree must be whacked, because in mainline there certainly is no twl6040* in mfd.
  468. [11:15:06] <LetoThe2nd> gnah, my bad.
  469. [11:15:20] <LetoThe2nd> mentally blank what i just said, please.
  470. [11:15:34] <TheSeven> smspillaz: are you sure that your PSU is working correctly and can handle enough current?
  471. [11:15:53] <TheSeven> noise coming from a PSU doesn't exactly sound good
  472. [11:16:13] <TheSeven> when powering it through USB it doesn't work either?
  473. [11:19:07] <LetoThe2nd> student_: looking into the files suggests that -core does probing, general functions and initialization, -irq does the irq handling, and the one in sound is plain audio handling. :-)

  475. [11:22:45] <TheSeven> hm, I don't have any drivers/mfd/twl6040* stuff in my 3.0 tree
  476. [11:23:09] <LetoThe2nd> TheSeven: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=tree;f=drivers/mfd;h=f5bc67133730d838709b698f7a8e13639f8a3de2;hb=c027a474a68065391c8773f6e83ed5412657e369
  477. [11:23:56] <smspillaz> TheSeven: through usb it doesn't work, the PSU is rated at 1A
  478. [11:24:13] <smspillaz> TheSeven: this is a really high pitched noise btw :)
  479. [11:24:37] <TheSeven> that's usually a sign of a rather cheap PSU :)
  480. [11:24:38] <Sonicadvance1> smspillaz, have a pregnant cap in your PSU?
  481. [11:24:47] <Sonicadvance1> super easy fix >>
  482. [11:24:49] <smspillaz> TheSeven: it is a cheap PSU :)
  483. [11:24:54] <smspillaz> Sonicadvance1: err, not sure what you mean ?

  485. [11:25:06] <smspillaz> Sonicadvance1: TheSeven: it's a variable voltage PSU
  486. [11:25:14] <Sonicadvance1> Nevermind me, I'm a crazy person
  487. [11:25:17] <smspillaz> (since that's the only one I could find locally)
  488. [11:25:31] <smspillaz> so right now it's on 5V
  489. [11:26:21] <av500> and you put it to 12V if the board is naughty?
  490. [11:26:32] <smspillaz> heh
  491. [11:26:40] <smspillaz> no I wouldn't do that :)
  492. [11:26:42] <TheSeven> av500: actually the board seems to be designed to even survive that
  493. [11:27:29] <Sonicadvance1> Maybe I should just hook the board to 120volt just to make it stop being a pain in my butt >>
  494. [11:28:13] <smspillaz> TheSeven: short of checking the voltage between pin1 and pin 29 and hooking up a jtag cable, I'm guessing this board is busted ?
  495. [11:28:59] * smspillaz is not really an expert on electronics
  496. [11:29:00] <TheSeven> the voltage is likely to be OK if the boards is responding to the power button
  497. [11:29:09] <Sonicadvance1> av500, Panda hates recursive std::lock_guard queues. I'm going to blame you now >>
  498. [11:29:12] <smspillaz> TheSeven: so something just came loose I guess
  499. [11:29:26] <av500> Sonicadvance1: sure
  500. [11:29:43] <TheSeven> smspillaz: possibly a broken pcb trace somewhere if you say that wiggling around the sd card slot did help earlier
  501. [11:29:56] <av500> Sonicadvance1: but I smell C++ and thus just shrug
  502. [11:30:07] <Sonicadvance1> lol
  503. [11:30:23] <smspillaz> TheSeven: yes, it was often failing to boot the SD unless I wiggled it around a bit
  504. [11:30:32] <av500> Sonicadvance1: I guess you need to put another wrapper around this mutex wrapper
  505. [11:30:56] <smspillaz> TheSeven: yeah, the hardware power button seems to work at least too
  506. [11:31:12] <Sonicadvance1> av500, apparently
  507. [11:31:27] * Sonicadvance1 uses recursive spinlocks
  508. [11:32:25] <smspillaz> TheSeven: rma then ?
  509. [11:32:42] <TheSeven> smspillaz: probably
  510. [11:32:54] <smspillaz> okay
  511. [11:33:02] <TheSeven> there seems to be no obvious reason for this failure...
  512. [11:33:11] <smspillaz> TheSeven: thanks for your help then anyways, at least I know that I have some grounds for an rma now :)
  513. [11:33:16] <smspillaz> rather than "oh shit I broked it"
  514. [11:33:39] <TheSeven> well, as I said, I've done way worse things to mine, and it's still happy
  515. [11:33:47] <smspillaz> TheSeven: like ?
  516. [11:34:43] <TheSeven> all kinds of touching the board while powered (esd risk), reverse polarity power supply, fiddling with internal voltages, ...
  517. [11:34:58] <koen> ESD is a myth invented by 3M
  518. [11:35:09] <koen> isn't that right av500?
  519. [11:35:17] <TheSeven> it even survived -4V on Vbat for a couple of seconds (damn, that just shouldn't have happened)
  520. [11:35:26] <av500> koen: yes, to sell more plastic bags

  668. [15:47:25] <av500> student_: how about asking the people where you got the crane from?
  669. [15:47:55] <TheSeven> janimo: you can get at the EDID data using i2cdump
  670. [15:48:10] * jojobest1 (~joffrey@192.93.161.12) Quit (Quit: Leaving.)
  671. [15:48:12] <TheSeven> you might need to plug the monitor into the DVI plug for that to work though
  672. [15:48:40] * buckiller (~buckiller@192.94.92.14) has joined #pandaboard
  673. [15:49:02] <prpplague^3> student_: like i said, try #beagle , since the crane is an off shoot of their product line
  674. [15:49:06] <janimo> Well, I can get the monitor EDID data if I plug it to my laptop (VGA). But I thought the Panda had edid files exposed, that's what I saw on a wikipage dealing with debugging panda/hdmi
  675. [15:49:24] <janimo> TheSeven, I have no DVI plug though
  676. [15:49:44] <TheSeven> i meant the DVI port on the pandaboard, instead of the HDMI one (both are actually HDMI sockets)
  677. [15:49:45] <prpplague^3> TheSeven: you can create a page on elinux.org or omapedia.org for this issue and post info there
  678. [15:50:00] <av500> janimo: cat /sys/devices/platform/omapdss/display1/custom_edid_timing
  679. [15:50:11] <av500> no?
  680. [15:50:12] <janimo> TheSeven, av500 thanks, I'll try that
  681. [15:50:35] <TheSeven> the file listed on the wiki has been gone for quite some time now IIRC
  682. [15:51:37] <janimo> av500, I have a file called timings there with content like this 23500,640/48/80/32,480/3/7/4
  683. [15:51:52] <janimo> but no file with edid in its name. This is 3.0
  684. [15:52:41] <prpplague^3> TheSeven: which file?
  685. [15:52:48] <janimo> display1 looks better, actually represents what the monitor can do : 119000,1680/48/80/32,1050/3/21/6
  686. [15:54:27] <av500> janimo: good
  687. [15:54:28] <janimo> no activity n dmesg when pluggin the hdmi cable in/out of the two panda sockets
  688. [15:54:46] <av500> janimo: sorry, no idea for 3.0
  689. [15:54:54] <av500> it works for me with the ti patched .35
  690. [15:54:56] <TheSeven> prpplague: /sys/devices/omapdss/display0/edid IIRC
  691. [15:55:06] <av500> TheSeven: thats raw edid, no?
  692. [15:55:21] <janimo> right, maybe there's a regression or yet unported feature in 3.0
  693. [15:55:29] <TheSeven> not sure if it was really that file, but I remember looking for a missing file that was supposed to contain my edid info some months ago as well
  694. [15:55:44] <janimo> anyway, I sometimes got the monitor active when rebooting, but it happens rarely

  698. [15:56:55] <av500> they tend to work
  699. [15:57:09] <av500> unless they are LG
  700. [15:57:22] <av500> or glare at TI to get HDMI fixed
  701. [15:57:42] <janimo> well I only have on e monitor (Samsung), not gonna get one just for the panda :(
  702. [15:57:47] <TheSeven> s/glare at TI/poke rsalveti/? :)
  703. [15:58:11] <av500> TheSeven: yes, but that "fix" is a "rewrite"
  704. [15:58:27] <janimo> I think rsalveti knows about the issues, but if they are bugs needing to be chased down and fixed there's no trivial solution
  705. [15:59:12] <janimo> at this point I would have liked to help debug, but even the files mentioned in the debug page are missing :)
  706. [15:59:25] <TheSeven> yeah, tracking down why it didn't like my SHARP tv was fun, he helped me a lot :)

  737. [17:45:52] <gnif> hi all
  738. [17:46:28] <gnif> I have an early adopters board that I am trying to use the usbboot from omap4boot
  739. [17:46:45] <gnif> works fine to the point of uploading the image
  740. [17:47:10] <gnif> but if I printf the read data in usb_read on the device, its just junk
  741. [17:49:16] <gnif> this is the data that it supposedly received "00 00 01 00 00 28 00 1d 00 00 01 00 00 24 00 44 00 00 01 00 00 28 00 1d 00 00 01 00 00 24"
  742. [17:50:07] <gnif> anyone have any ideas?
  743. [17:55:51] <gnif> I would say that the DDR was not initialised properly, or something since the stage1 loader uploads and runs fine

  773. [19:17:06] <gnif> GrueMaster, when the image is uploaded to the pb, it receives junk
  774. [19:17:32] <gnif> i threw a printf into the usb_read method, and the data received is rubbish
  775. [19:17:43] <GrueMaster> Very odd.
  776. [19:18:14] <gnif> yeah, i figured it must be my pb since its an early adopter board
  777. [19:18:30] <gnif> since the ddr is lower spec in it

  876. [22:03:08] <Alison_Chaiken> Methinks I must do something in files with mydroid/devices/ti/pandaboard that is not described in the instructions, but reading the Makefiles and guessing has not yet produced a working result.

  889. [22:09:51] <riot> whats the best way to speak to an atmega thats supposed to do sensor input? I thought of using rs232. Any better suggestions? I'd need rather high bandwidth, like 400 kHz i2c would offer (where to best connect i2c to?)
  890. [22:11:19] <prpplague> riot: need to explain what you are trying to accomplish a little better. are you connecting a sensor to an atmega and then to something else like a pc?

  892. [22:13:06] <riot> i'll connect lots of sensors (voltage, temperature, windspeed, humidity, 9dof) to an atmega that samples data via i2c/spi and should be connected to the pandaboard. I want to read data from that atmega (preferrably in python, somehow) and send instructions for PWM-Outputs to the same chip.

  896. [22:13:48] <riot> hiho =)
  897. [22:13:53] <tecdroid> hey riot
  898. [22:14:07] <prpplague> riot: if you need irq based, you probably want to use something else
  899. [22:14:15] <riot> no, polling should be fine
  900. [22:14:23] <tecdroid> why this prpplague ?
  901. [22:14:29] <prpplague> riot: have a look at the schematic for the trainer board
  902. [22:14:34] <riot> i'll just ask the controller wether it has any new data every few ms and distribute it
  903. [22:14:39] <prpplague> tecdroid: i am sorry i did not understand your question
  904. [22:14:41] <riot> trainer board.. eh... okay
  905. [22:15:03] <prpplague> riot: http://www.elinux.org/BeagleBoard_Trainer
  906. [22:15:05] <tecdroid> why just polling with uart? ?
  907. [22:15:08] <riot> prpplague: tecdroid's a friend, we're constructing together :)
  908. [22:15:14] <riot> prpplague: thanks.
  909. [22:17:37] <prpplague> tecdroid: you can use uart with an irq for incomming data, however if you need for instance, an irq to be triggered the instance a specific datapoint is available, doing this via uart alone can introduce a lot of delay
  910. [22:18:34] <Alison_Chaiken> prpplague, if you look in mydroid/build/ and subdirs, there are a lot of .mk files. In device/ti/pandaboard there are many identically named .mk files. Some file must have to get linked or copied somewhere, methinks, but I haven't been able to guess which.
  911. [22:18:38] <tecdroid> which is quite normal in an interrupt driven system
  912. [22:19:04] <prpplague> Alison_Chaiken: yea getting setup to do the builds now, making notes as i go
  913. [22:19:34] <tecdroid> but this delay can't be very large
  914. [22:19:53] <prpplague> tecdroid: depends on how well you implement the uart protocol
  915. [22:20:33] <tecdroid> on which side? panda or the slave board?
  916. [22:21:44] <prpplague> tecdroid: well based on the information you have given me, you will need to implement a protocol for your specific configuration, which means you will need to have some sort of client and/or driver on the linux side as well as an implementation of the protocol in the avr

  919. [22:22:59] <tecdroid> yes, my plan was to use an uart as tty, so i just have to implement some kind of shell in my avr
  920. [22:23:45] <prpplague> hehe, you are still implementing a protocol
  921. [22:24:13] * prpplague has had this conversation many times before
  922. [22:24:21] <tecdroid> yes but i don't have to build an extra driver
  923. [22:24:42] <tecdroid> or.. better, i don't have to implement a kernel space driver
  924. [22:24:55] <prpplague> tecdroid: correct, but you DO have to implement the protocol
  925. [22:25:40] <tecdroid> okay, that's right.. i just don't want to implement some hadware abstraction on the panda board..
  926. [22:26:25] <prpplague> tecdroid: techincally that is what you are doing, just not in kernel space
  927. [22:26:33] <riot> tecdroid: jeedi says: we linewrite from the atmel into rs232 and pump that stream to the pandaboard, linux manages io, i do "open('/dev/ttyS0', 'r')" and am happy with a blabbering stream of sensor data
  928. [22:26:40] <ds2> implement SLIP
  929. [22:27:14] <tecdroid> is there any device node for usart4?
  930. [22:27:23] <prpplague> tecdroid: yes
  931. [22:27:36] <prpplague> riot: ok, but you have to do something with the data
  932. [22:27:44] <prpplague> riot: you have to decide on the format of the data
  933. [22:27:50] <riot> prpplague: run a regexp on each line i received ;)
  934. [22:27:56] <prpplague> riot: you have to consider what happens if it gets out of sync

  937. [22:28:07] <riot> out of sync? to what?
  938. [22:28:23] <riot> i thought the kernel would handle that..?
  939. [22:29:07] <tecdroid> okay.. if there's a node i can open we can communicate through usart4. that's all i need to know. my avr board doesn't need any level converter to rs232 level

  945. [22:29:57] <riot> i'm too young for school. We're building an ARNV (Autonomous Robotic Naval Vehicle)
  946. [22:30:28] <riot> or, at least we're trying =)
  947. [22:31:02] <prpplague> riot / tecdroid hehe, you guys are in for some fun, your questions and planning, are extremely common with folks who are trying to integrate microcontrollers to larger systems running an OS
  948. [22:31:53] <prpplague> riot / tecdroid you can do a data stream, but understand that will be polling based, and you have very little margin for error in the data
  949. [22:31:54] <tecdroid> no, i just had one question.. there is a /dev/usart4- however it's named. so riot can talk to my avr
  950. [22:32:13] <ds2> bah...trivial stuff. use what is avialable and stop reinventing the wheel
  951. [22:32:28] <prpplague> tecdroid: depending on the system it will normally be /dev/ttyO3
  952. [22:32:36] <tecdroid> okay, thanks :)
  953. [22:33:17] <ds2> or use a slave setup with I2C or SPI
  954. [22:33:38] <prpplague> ds2: yea there is already an avr lib for that
  955. [22:33:55] <tecdroid> yes, i'm using peter fleury's lib
  956. [22:34:30] <ds2> for which? (sorry, I am lagging by about 2 minutes; saturated link)
  957. [22:34:36] <prpplague> ds2: hehe
  958. [22:34:41] <tecdroid> i??c
  959. [22:34:53] <prpplague> tecdroid: avr to linux lib?
  960. [22:35:22] <tecdroid> no, just for i??c com to devices
  961. [22:36:04] <prpplague> tecdroid: there is an avr lib specific done with an i2c protocol implementation for working with linux
  962. [22:36:20] <tecdroid> but my i??c is already in use..
  963. [22:36:28] <ds2> that sounds like master support... you want slave support on the AVR side
  964. [22:36:32] <prpplague> tecdroid: anyway, feel free to drop in for questions, have a look at the schematics for the trainer
  965. [22:36:41] <ds2> or bitbang with Linux as the master on SPI
  966. [22:36:53] <tecdroid> yes, i'll do.. but now i need some sleep..
  967. [22:38:39] <tecdroid> gn8
