**** BEGIN LOGGING AT Fri Mar 23 02:59:58 2012 Mar 23 04:37:41 * mranostay waves Mar 23 04:38:26 yo Mar 23 04:39:01 Moooo Mar 23 04:40:47 * mranostay pokes around bonescript Mar 23 04:41:22 adding meat? Mar 23 04:42:35 seeing if should do my geiger app in bonescript Mar 23 04:49:34 probably will just build my HV probe Mar 23 04:57:13 mranostay: what kind of sense element are you settling with? Mar 23 05:01:12 ds2: you mean tube? Mar 23 05:03:37 mranostay: you are going with a tube? thought you might be using that term generically Mar 23 05:04:49 (vs a scitilator (sp) or other detectors) Mar 23 05:25:23 ds2: yeah plain old tube Mar 23 05:28:50 mranostay: how sensitive of a tube are you using? alpha/beta/gamma tube? Mar 23 05:36:51 ds2: SBT-9 Mar 23 05:42:41 cheap LND-712 basically Mar 23 05:45:24 electronics goldmine stuff? Mar 23 05:49:23 ebay'ed it Mar 23 06:11:19 so sakoman, do you know the status of the musb gadget stuff? Mar 23 06:32:36 dammit :/ Mar 23 06:32:54 I googled "arm conditions" to try to find a reference for the condition flags Mar 23 06:33:03 now AdSense thinks I have carpal tunnel. Mar 23 06:34:08 XMPPwocky: you will someday :) Mar 23 06:49:59 http://pastebin.com/2VBPA2nM this basically does: while (; i < j; i++) { ... }, yes? Mar 23 06:59:43 * mranostay notes he has no real sleep schedule anymore Mar 23 06:59:45 ... Mar 23 07:05:22 green13: ah, probably not Mar 23 07:05:26 woops Mar 23 07:15:59 bummer, u-boot has two usb gadget frameworks, and old one, and a new one Mar 23 07:16:10 musb is supported on the old framework Mar 23 07:16:16 ethernet is supported on the new framework Mar 23 07:17:22 isn't ethernet usbhost? Mar 23 07:17:50 drivers/usb/gadget/ether.c Mar 23 07:20:07 I stand corrected! Mar 23 08:59:34 Hello, I have a short question related to booting Ubuntu on the Beaglebone Mar 23 08:59:47 I downloaded the demo image for 11.10 and the boot seems to go fine, however, I cant log in Mar 23 09:00:17 when the login prompt is output over the serial, I seemingly cant send any keyboard strokes to the device Mar 23 09:00:24 has anyone experienced anything similar? Mar 23 09:01:58 how are you connecting to the serial device? (both software and hardware wise) Mar 23 09:02:00 http://www.buildinginternetofthings.com/2012/03/22/femtoduino-the-smallest-arduino-clone-available/ Mar 23 09:02:24 through USB Mar 23 09:02:40 I remembered wrong, I cant send any keystrokes through the serial Mar 23 09:02:48 so it seems to be read-only Mar 23 09:03:35 check your terminal emulator serial port settings Mar 23 09:03:48 flow control off Mar 23 09:03:54 ok, I just use screen Mar 23 09:04:12 meta-a-f in screen IIRC Mar 23 09:05:17 hm, no luck, it still wont accept any input Mar 23 09:09:03 there is something happening though, the device complains that getty has been hanging for too long Mar 23 09:11:45 minicom and picocom also show the same behavior Mar 23 09:20:37 and nanocom? Mar 23 09:20:45 femtocom? Mar 23 09:27:06 * dm8tbr throws a Gigacom at av500 Mar 23 09:30:33 dm8tbr: which reminds me of that pair of gigaset M101 that I have Mar 23 09:30:50 64kbit uart over dect :) Mar 23 09:31:16 teehee, yeah, back in the days(tm) Mar 23 09:31:30 worked like a charm in the dialup eara, no new to drill holes in the flat Mar 23 09:32:19 -a Mar 23 09:34:02 but also convenient to extend Uni club 'network' to the dorm ;) Mar 23 09:34:17 or that Mar 23 09:34:42 hmm, I should hook that to the nas box Mar 23 09:34:43 "back in the day" yeah. how i do NOT miss those days. Mar 23 09:35:40 LetoThe2nd: http://www.youtube.com/watch?v=cm0iQz24Aac Mar 23 09:37:09 av500: seen them three ties :) Mar 23 09:37:14 times, even Mar 23 09:37:48 was not wearing my vodka-tractors-rock n roll hoodie when we met last time, i guess ;P Mar 23 10:12:47 Gah Mar 23 10:13:09 I think push and pop are broken on my baglebone, or I'm not doing it right Mar 23 10:18:49 or both Mar 23 11:05:44 koen: any luck with these latest 3.5 LCD timings? need someone to test? Mar 23 11:29:02 WTF. Mar 23 11:29:53 ldr sp, =stack_start_address; push {r0, r1}; pop {r0, r1}; push {r0, r1, r2, r3}; pop {r0, r1, r2, r3} Mar 23 11:30:17 r2 and r3 are corrupted. Mar 23 11:30:21 I'm pretty sure push and pop work fine Mar 23 11:30:45 any special place sp has to be? it's word aligned Mar 23 11:30:52 remember the stack grows downwards Mar 23 11:30:59 yep Mar 23 11:31:07 i can actually view memory and see it Mar 23 11:31:15 and the stack must be word-aligned at all times Mar 23 11:31:19 and the second push call just seems to no-op Mar 23 11:32:08 trust me, push and pop work Mar 23 11:32:09 mru: yep, stack_start_address is 0x8200fc00 Mar 23 11:32:28 mru: i know, but i'm trying to figure out why they won't in this case Mar 23 11:33:19 * XMPPwocky tries to make a test case Mar 23 11:42:15 oh, now it works Mar 23 11:42:17 course. Mar 23 11:43:47 night Mar 23 11:43:58 falls Mar 23 11:45:16 and is trampled by his horse Mar 23 11:46:37 oh, carp. i know what it was Mar 23 11:46:44 do tell Mar 23 11:47:08 and are you sure it was a carp, not a trout? Mar 23 11:47:29 the trout is after all the fish of choice on irc Mar 23 11:47:29 boot.bin is old Mar 23 11:47:31 was probably the sole reason Mar 23 11:47:49 av500: :/ Mar 23 11:49:38 are we doing fish puns today? Mar 23 11:50:00 but in fresh bins ... Mar 23 11:50:26 mru: i don Mar 23 11:50:37 i'm not sure WHAT the halibut we're doing Mar 23 11:51:08 but the rest of us seem to have cod on quickly Mar 23 11:52:08 come on, salmon else has to come up with one Mar 23 11:52:34 but you're doing just fin on your own Mar 23 11:53:22 i really ought to go to bed, so can we resume this at a more opportuna moment? Mar 23 11:53:47 * av500 does not eel like it Mar 23 12:01:21 hello, i am trying to compile a tcl/tk application on the BBoard rev c5.. http://pastebin.com/LbuzQXGn Mar 23 12:01:53 i am not sure if this is right place to ask about this.. please dont be angry with me. Mar 23 12:01:56 tcl is not compiled Mar 23 12:01:57 :) Mar 23 12:02:17 but cannot find anything about tk-lib-dev on the web Mar 23 12:03:05 yes it is because there is no tklib listed in Angstrom kernel Mar 23 12:03:13 i mean kernel --> linux Mar 23 12:03:28 where should i get that? is it impossible? Mar 23 12:04:05 no, the tcl language is not compiled Mar 23 12:04:05 tk-lib-dev Mar 23 12:04:22 but there is a tcl library for embedding a tcl interpreter into an application Mar 23 12:04:25 what do you mean? sorry.. Mar 23 12:05:07 yes i did successfully install tcl package. Mar 23 12:05:16 good Mar 23 12:05:31 but you're missing the -dev packages, apparently Mar 23 12:05:31 i am compiling puredata on the board Mar 23 12:05:46 that needs tcl-dev Mar 23 12:05:52 tk-dev Mar 23 12:05:54 also. Mar 23 12:06:35 is there anyway that i can skip them or.. find alternative? generally speaking.. Mar 23 12:07:36 when some app needs -dev packages to be complied? Mar 23 12:08:05 sounds stupid.. but i am not really understanding.. this situation.. Mar 23 12:08:32 -dev package is something.. of raw codes.. on the things, right? Mar 23 12:08:32 you can skip them if you remove tcl from that app Mar 23 12:08:42 only then? Mar 23 12:08:44 but I guess then the app does not work any more Mar 23 12:08:44 um.. Mar 23 12:08:49 yes. Mar 23 12:08:56 if you want to compile an app to use tcl, you need tcl headers Mar 23 12:08:57 the -dev packages are header files and (sometimes) static libs Mar 23 12:09:08 thus you need the -dev package Mar 23 12:09:13 opgk Mar 23 12:09:35 then.. you mean that i can use any header files for tcltk... for BBoard? Mar 23 12:09:41 i mean.. angstrom? Mar 23 12:09:50 if the interface is same Mar 23 12:10:09 but still.. they should be configured.. properly.. right? Mar 23 12:10:35 http://www.angstrom-distribution.org/repo/?pkgname=tcl-dev Mar 23 12:10:41 why not just install that? Mar 23 12:10:48 opkg does not support.. tcl-lib-dev Mar 23 12:10:56 only.. tcl-dev Mar 23 12:10:59 then try tcl-dev Mar 23 12:11:07 is it also includes tcl-lib-dev? Mar 23 12:11:14 how would I know Mar 23 12:11:18 I just googled that Mar 23 12:11:30 oops.. sorry Mar 23 12:11:39 anyway thanks a lot Mar 23 12:11:50 sergey, larry: ^^^^ Mar 23 12:12:17 thank you very much! :) Mar 23 12:24:55 Right now my SPI is outputting on D1 but I would like it to output on D0 is that possible? Mar 23 12:25:23 change the pinmux? Mar 23 12:27:16 hey :) Mar 23 12:27:17 I changed the pin mux on the D1 to be in mode 7 (GPIO) and it still outputs data Mar 23 12:28:05 Does the pin mux need to be changed at a particular time? perhaps before spi board registration? Mar 23 12:28:19 hmmm Mar 23 12:28:40 icota: no luck Mar 23 12:29:13 the 800x480 timings work on the 3.5" as well, but as one would expect, it is cropped Mar 23 12:29:24 koen: i think there might be some modesetting via SPI to be done Mar 23 12:29:39 icota: I tried your timings in 16 and 24 bit mode, no dice Mar 23 12:30:31 koen: what is that mystery panel? Mar 23 12:30:43 av500: 3.5" lcd 320x240 for a cape Mar 23 12:31:44 av500: CDTech S035Q01 Mar 23 12:31:48 that's so ............ 2003 Mar 23 12:32:39 icota: from what I can decypher from the datasheet is that the pixclock needs to be between 8 and 33 mhz for non 24 bit modes Mar 23 12:32:59 koen: yeah, the datasheet is really bad Mar 23 12:33:28 koen: what does the whole SPI example code do? i don't really get it Mar 23 12:34:02 don't know, I'd like to avoid using the SPI setup Mar 23 12:34:25 icota: can you try the 800x480 mode and see if that gets a picture on your lcd as well? Mar 23 12:34:48 my plan was to go from there and adjust the resolution, pixclock and porches to step by step Mar 23 12:35:08 but since I destroyed my lcd it involved a roundtrip to texas to test Mar 23 12:35:32 icota: i'll let you know in half an hour if it works on my side Mar 23 12:35:39 if so, i'll try to go from there Mar 23 12:35:49 fbset should be enough? Mar 23 12:36:26 koen: you work in dallas? Mar 23 12:36:41 I work from home in the netherlands, but the office is in the dallas area Mar 23 12:37:01 icota: fbset doesn't work, the kernel needs to get rebuilt Mar 23 12:37:12 well, fbset only works to read the timings, not to set them Mar 23 12:37:27 which is why this video works is *$($*#($*(# annoying me Mar 23 12:37:53 good thing i have the next 6 hours free Mar 23 12:38:00 don't know the details of your case, but you can set the timings via sysfs Mar 23 12:38:34 tomba: not on am335x, that's da8xx-fb.c based Mar 23 12:38:53 koen: what mode are you using? Mar 23 12:38:56 ok, never mind then =) Mar 23 12:38:57 which is a dumb driver for an even dumber framebuffer Mar 23 12:39:02 av500: mode? Mar 23 12:39:11 pixclock needs to be between 8 and 33 mhz for non 24 bit modes Mar 23 12:39:13 ^^^ Mar 23 12:39:26 16bpp Mar 23 12:40:56 koen: this one: http://wenku.baidu.com/view/8426530f844769eae009edfc.html ? Mar 23 12:42:55 av500: yes, that's the one Mar 23 12:43:08 av500: koen has a more recent datasheet though Mar 23 12:43:43 its still boring 2003 stuff Mar 23 12:44:05 I'd settle for a datasheet I can actually read Mar 23 12:44:11 without pixelated diagrams Mar 23 12:44:19 use the baidu one Mar 23 12:50:28 don't recall the baidu one being all that better, hard to tell between your 6/8/9's Mar 23 12:51:36 I'm trying to access memory at 0x481A0000 (SPI1 config) but it fails although I can easily access GPMC config memory or UART config memory, is there something special about McSPI config registers? Mar 23 12:57:06 Basically I'm trying to make sure that my SPI is in master mode along with other configs Mar 23 12:58:13 From the TRM (spruh73c) figure 24-1 It shows that D0 should be an output if the SPI is in master mode Mar 23 13:07:00 jsabeaudry: AIUI you can choose what d0 and d1 are Mar 23 13:10:18 koen, yup I confirmed that in the TRM but it seems I need to enable something to be able to access the McSPI configuration registers, if I was on OMAP3530 it would be "McSPI functional (CM_FCLKEN1_CORE) and interface (CM_ICLKEN1_CORE) " but I haven't found the equivalent yet Mar 23 13:12:40 ah perhaps the CM_PER_SPI1_CLKCTRL I'll try it out Mar 23 13:16:16 I have a hardware problem, is this the right place to ask about it? Mar 23 13:16:33 depends on the hardware Mar 23 13:16:52 and the problem Mar 23 13:17:55 I've had my beagleboard for two days. This morning I plugged in the power and just got a red light, and it's been that way since. Mar 23 13:23:59 any ideas why it might do that? Mar 23 13:26:04 (and how I can make sure not to do it in the future)? Mar 23 13:27:11 bad voltage Mar 23 13:31:46 it's the adapter that came with the board though. Mar 23 13:35:35 is it a beagle-xm? Mar 23 13:36:12 Yes. Mar 23 13:36:33 (beagle classic doesn't have the overvoltage protection) Mar 23 13:36:48 but neither model comes with a psu Mar 23 13:37:07 where did you buy it? Mar 23 13:37:19 Digikey sells a power adapter, which is listed alongside the beagleboard Mar 23 13:37:30 ok Mar 23 13:37:47 are you sure you didn't plug in some other psu by mistake? Mar 23 13:37:56 I only have the one. Mar 23 13:38:20 It wasn't fully plugged in, so I pushed it all the way in, and now I get the red light. Mar 23 13:38:28 then check the voltage with a meter Mar 23 13:38:56 ok Mar 23 13:39:04 what should it be, 5 volts? Mar 23 13:39:07 yes Mar 23 13:39:32 ok Mar 23 13:39:53 will do that this afternoon when I have access to a meter Mar 23 13:45:08 Is it normal that on my first SPI transmission the CM_PER is reset along with all my settings? Mar 23 14:10:45 hello Mar 23 14:10:56 question: Mar 23 14:11:29 Is beaglebone kernel/linux compiled with v4linux Mar 23 14:11:37 or video4linux Mar 23 14:11:40 Thanks Mar 23 14:22:52 Is beaglebone kernel/linux compiled with vedo4linux Mar 23 14:23:25 zcat /proc/config.gz and find out Mar 23 14:23:33 depends on the kernel Mar 23 14:24:29 koen correct me if i'm wrong but usualy it should be compiled with it Mar 23 14:27:58 compiled with what? Mar 23 14:28:17 video4linux Mar 23 14:30:22 15:23 < koen> zcat /proc/config.gz and find out Mar 23 14:30:31 I havent recieved the board yet Mar 23 14:31:10 I was planning on buying usb cam in mean while, so I wanted to ask if it does support v4linux, Mar 23 14:31:35 if not is it easy to comile kernel for the board? Mar 23 14:31:51 for those who can read: yes, IMHO :) Mar 23 14:32:08 what if you can't read? Mar 23 14:32:23 prpplague: then its not easy. :P Mar 23 14:33:21 for compiling the kernel being able to type should be enough Mar 23 14:33:22 you could use a screenreader Mar 23 14:33:28 you talking to me leto Mar 23 14:33:28 it would read it for you Mar 23 14:34:00 ogra_: screenreaders don't count, they are just format converters. Mar 23 14:34:40 indeed, but it helps as long as you can *hear* you dont need to be able to read Mar 23 14:34:52 if you cant hear either you are lost indeed Mar 23 14:36:03 as i said. ability to read, be it using what ever format conversion you nedd/prefer. :P Mar 23 14:36:22 he still can watch youtube tutorials...but only if his kernel was compiled with video4linux :) Mar 23 14:36:47 hi, what it the meaning of omapfb.vram=0:8M,1:4M,2:4M in uEnv.txt? Mar 23 14:38:02 stuk_gen: does this help http://www.elinux.org/BeagleBoard/video Mar 23 14:38:40 Hi All, I'm new to the beaglebone... I have it booted up and attached to the network and I can ssh to it and iotherwiise treat it like another server on the network. My task it to create a custom image that can be distributed. I am going to use bitbake to compile the kernel and the console image and after that I want to add some things like rvm (ruby version manager), RUby, a web server (nginx probably) and a ferw other thi Mar 23 14:39:26 you might want to limit your sentences to 200 chars or less ;) Mar 23 14:39:39 mru: your town is on slashdot Mar 23 14:39:50 poor slashdot. Mar 23 14:41:03 So can I build the essential and install my add-on and then duoplicate that? Mar 23 14:41:12 thats good to hear kelleysislander how can we help you? Mar 23 14:41:25 apparently lots of illegal hobbits there Mar 23 14:41:37 Thanks for helping with the rules! I'm a noob here so thabnks again! Mar 23 14:41:42 nasty hobbitses? Mar 23 14:42:04 Ha Ha !@@ Mar 23 14:42:43 sure kelleysislander you can build your image and dd it Mar 23 14:42:43 I am tasked with building a custom distr which will have a web server, ruby, the padrino web framework Mar 23 14:43:11 I have a bitbake recipe for some special device drivers that need to be baked in. After that... Mar 23 14:43:17 you might even take one of the angstrom demo images and just install the needed packages Mar 23 14:43:23 koen: about what? Mar 23 14:43:44 oh ok then forget about the demo images :) Mar 23 14:43:48 can I simply add my extras and crate a single bootable image? Mar 23 14:43:49 mru: a local pub is getting sued because it's called "the hobbit" Mar 23 14:43:53 oh that Mar 23 14:43:56 that's old news Mar 23 14:44:05 I said 'slashdot', didn't I :) Mar 23 14:44:34 why "forget the demo image"? Mar 23 14:44:44 they're keeping the name Mar 23 14:44:57 if you need your own drivers in the kernel you need to bitbake it Mar 23 14:44:57 and they were not sued Mar 23 14:45:16 the lawyers sent them a somewhat threatening letter Mar 23 14:45:18 yes I have an oebb.sh for that Mar 23 14:48:41 so then go ahead and start baking :) Mar 23 14:50:13 So after bitbaking I can add my other stuff and then crteate the bootable image in one shebang? Mar 23 14:51:10 you bitbake the kernel with virtual/kernel and then you bitbake your image (e.g. console-image) Mar 23 14:52:34 OK, have that done... Mar 23 14:53:02 Then aftet that boot up on that image and install my extras on top of that??? Mar 23 14:53:21 koen: I'm not getting anything with your timings, how do you test? Mar 23 14:53:36 * mdp has to wonder if kelleysislander is local to him Mar 23 14:53:59 I'm in Dallas Mar 23 14:54:03 ok :) Mar 23 14:54:11 and you? Mar 23 14:54:17 that could be one side of the road...you can also bitbake you apllications ins the bitbake process Mar 23 14:54:19 ohio Mar 23 14:54:30 I'm from Ohio Mar 23 14:54:38 and am going to kelleys island tomorrow Mar 23 14:54:44 kelleysislander: ok, so you know why I asked then :) Mar 23 14:54:58 cool, great weather right now, as you probably know Mar 23 14:55:02 martrom how would I bitbake my extras into the process? Mar 23 14:55:17 mdp - it's been warmer there than here ha ha Mar 23 14:55:54 mdp yep us Ohioans stick together !@@ Mar 23 14:55:57 kelleysislander: yeah, everybody with a "seasonal vehicle" has them out already..it's a bit unusual to be rockin the 83F in mid-march :) Mar 23 14:56:24 Martron - is one approach betther than the other? Mar 23 14:57:03 http://www.armbedded.eu/documentation/html/linuxguide/ch07s03.html Mar 23 14:57:29 kelleysislander: same shit :) Mar 23 14:57:39 So my overall approach is to bitbake the kernel and console image, also need ssh so I can connect... Mar 23 14:58:44 martron thanks for that excellent resource Mar 23 14:59:42 always depends on how the future use will be....if you just have to create ONE image, do it your way...if you have to keep that image on a current kernel all the time you might want to just fire up one bitbake of your own recipie Mar 23 14:59:47 OK, that's great fr now, my fortst task is to bitbake kernel and console image. Then with that success under the belt add extras. Mar 23 15:00:25 one very fist step could be just to use the demo images Mar 23 15:00:35 and put your applications there Mar 23 15:00:42 How might I concoct a recipe for something custom such as "RVM - Ruby Version manager"? Mar 23 15:00:55 depends on how fast you need to prototype it Mar 23 15:00:59 Martron - sounds like a good approach Mar 23 15:01:26 I had a fellow do it initially and the first compile took 12 hrs sunsequent ones were less die to compiler caching Mar 23 15:02:32 OK, baby steps first - I will do the kernel and console and the specific oebb.sh from the client and see how that works. Mar 23 15:02:38 i dont know about ruby but you might check at angstrom what they already have http://www.angstrom-distribution.org/repo/ Mar 23 15:03:27 On RUby I have successfully compiled and am using a ruby on the BB... pretty cool it really didn't take much more time to compile than on my i7 MB Pro! Mar 23 15:04:18 blame apple Mar 23 15:04:31 use linux :) Mar 23 15:04:43 Martron FYI: the "rvm" program makes compiling rubies super easy. I tried "opkg install ruby" and it was not found so now I am upgrading to see if it shows up Mar 23 15:05:07 do a opkg udate first Mar 23 15:05:18 I had the compile done on an Ubuntu box which is what I will be suiong, just usiong the mac for comparison Mar 23 15:05:24 you did a opkg upgrade?? Mar 23 15:05:40 yes it is still running lots of packages!@@ Mar 23 15:05:53 hopfully it will boot afterwards Mar 23 15:06:01 Ha Ha! Mar 23 15:06:04 no kidding Mar 23 15:06:13 yeah ... gulp! Mar 23 15:06:32 there were problems with the systemd not doing the post installation steps Mar 23 15:06:48 took me quite a week to find that out Mar 23 15:06:53 yikes Mar 23 15:07:12 koen might has fixed that already :) Mar 23 15:07:29 you'll find out soon Mar 23 15:07:40 so if it doesn't that what? Mar 23 15:07:54 no way to revert? Mar 23 15:08:13 i put the demo image on my card Mar 23 15:08:29 you can upgrade the kernel though Mar 23 15:10:07 still running the upgrade the outout is nine liles long... Mar 23 15:10:48 removing the git stuff now Mar 23 15:12:34 Martron: If this ends up hosed where to get a new demo image? Mar 23 15:13:35 http://www.angstrom-distribution.org/demo/beaglebone/ Mar 23 15:16:01 Martron: Oh yeah, thanks Mar 23 15:17:58 Martron: Oh yeah, I'm on the beaglebone not beagleboard if that makes a diff... Mar 23 15:18:11 koen: gsoc rejection meeting? Mar 23 15:18:59 this is why i pointed you the beaglebone demos :) Mar 23 15:20:15 Martron: Yep, thanks for that Mar 23 15:38:02 What kind of thing could cause a functionnal clock to get disabled? Mar 23 15:38:17 (on the am335x) Mar 23 15:38:29 you didnt wind it up in time ? Mar 23 15:40:02 its called dysfinctional clock now Mar 23 15:44:40 av500: where, when? Mar 23 15:45:07 15 min in #gsoc Mar 23 15:45:08 icota: I send the uImage to texas and they boot and report back :) Mar 23 15:45:18 icota: note that backlight is turned off Mar 23 15:45:24 koen: is that a BAAS? Mar 23 15:45:28 koen: i did turn it on Mar 23 15:48:32 jsabeaurdry, you have a PM enabled am335x kernel and the block is being clock gated? Mar 23 15:48:44 * mdp throws out one possibility Mar 23 15:50:19 mdp, what is "PM enabled"? Mar 23 15:51:41 power management Mar 23 15:53:59 To be more specific, CM_PER_SPI_CLKCTRL gets reset when I pipe to /dev/spidev2.0 Mar 23 15:54:29 what kernel are you using? Mar 23 15:54:39 icota: I've seen the 800x480 timings work on the lcd, but nothing else :( Mar 23 15:55:33 koen: is the framebuffer 800x480 as well? i'm using your latest kernel from github and getting nothing Mar 23 15:57:03 mdp, I'm using kernel for koen's repo with a patch for spidev Mar 23 15:57:12 s/for/from/ Mar 23 15:58:03 ok, cool, wanted to be sure I'm looking at the same thing Mar 23 15:58:40 we have enough kernels to rival the number of flavors at baskin-robbins Mar 23 16:00:24 icota: yes, have a look at the lcd7 setup routines in the boardfile Mar 23 16:00:46 jsabeaudry: CM_PER_SPI2_CLKCTRL, I imagine? Mar 23 16:01:29 CM_PER_SPI1_CLKCTRL Mar 23 16:01:46 er, yes, due to the kooky mcspi instance numbering Mar 23 16:01:46 gotcha Mar 23 16:06:35 could spidev possibly reset that stuff? Mar 23 16:07:09 not directly Mar 23 16:07:46 however, it can happen indirectly via the omap clock management framework (tied to hwmod) Mar 23 16:07:53 looking at it now Mar 23 16:08:51 jsabeaudry: since you mention that CM_PER_SPI1_CLKCTRL is reset, what are the contents before/after you access spidev2.0? Mar 23 16:09:58 I set it to 0x2, after echoing to spidev the value is 0x30000 Mar 23 16:11:49 koen, can you confirm that your branch is one that pulled in the PSP PM stuffs? Mar 23 16:11:59 IIRC, you mentioned that Mar 23 16:12:11 jsabeaudry: ok, thx.. Mar 23 16:16:33 jsabeaudry: in normal operation you should not have to touch clocks regs directly, this should happen automagically for you Mar 23 16:16:45 mdp: it has PM bits Mar 23 16:16:47 so you're seeing the management framework also writing to it obviously Mar 23 16:16:55 mdp: but proper PM requires the secret m3 firmware Mar 23 16:17:22 koen, is that pretty much the latest stuff? I know there's some system test on a "formal release" happening now..wondering if it's current with what's in those arago trees Mar 23 16:17:27 koen, ahh :) Mar 23 16:17:37 s/secret/sekrit/ Mar 23 16:17:56 all TI parts have to have sekrit m3 firmware for sexy features Mar 23 16:17:58 so right now it's non working cpuidble, broken cpufreq and suspend needs that firmware Mar 23 16:18:01 no idea on clock gating Mar 23 16:18:31 mdp, What is the normal way of setting SPI configuration, for example setting D0 to be the output pin like in figure 24-1 of the TRM ? Mar 23 16:18:55 I could not find another way of setting SPI configs Mar 23 16:18:59 well, my recommendation is to ignore figure 24-1 since it's misleading Mar 23 16:19:40 it's showing one possible use case rather than how the spi-omap2-mcspi.c driver is configured Mar 23 16:19:41 I need transmit only mode on pin D0 Mar 23 16:19:53 that's currently hardcoded in the mcspi master driver :-/ Mar 23 16:19:57 ah that is the file I need to modify? Mar 23 16:20:02 yep Mar 23 16:20:18 well that should do it Mar 23 16:20:24 I'll take a look Mar 23 16:20:32 thanks a lot for your help Mar 23 16:20:56
