**** BEGIN LOGGING AT Tue Oct 28 03:00:00 2014 Oct 28 03:51:41 I need a little help regarding BBB Oct 28 03:52:28 is there any light desktop for installing on ubuntu on BBB except LXDE? Oct 28 04:00:31 you can use blackbox or fluxbox Oct 28 04:00:41 those are pretty light, although they're barely a desktop Oct 28 05:36:00 hi Oct 28 05:36:19 dear sir i am trting to compile the kernel Oct 28 05:36:38 and following these steps Oct 28 05:36:51 http://elinux.org/Building_BBB_Kernel Oct 28 05:37:13 but after execute this command i got an error Oct 28 05:37:23 make ARCH=arm CROSS_COMPILE=arm-linux-gnu- uImage-dtb.am335x-boneblack gives me error saying "No rule to make target" Oct 28 05:37:28 plz help me Oct 28 05:37:58 ?? Oct 28 05:44:08 hi Oct 28 05:54:42 @jpfau...i tried to install blackbox and fluxbox but they are not working..nothing is appearing on the screen Oct 28 05:55:41 rao_: You need to start them. Did you add them to your xinitrc or trying to run them from an xterm while an X session is running? Oct 28 06:19:07 i didnt understand about it..can you please tell me or direct me to any link? Oct 28 06:20:16 https://wiki.ubuntu.com/CustomXSession---> can i follow this link? Oct 28 06:21:40 @jpfau...Sir...Can you guide me about this.? Oct 28 06:22:46 rao_: see how at the end of this file, it says "exec openbox"? https://wiki.ubuntu.com/CustomXSession#Sample_.2BAH4ALw.xinitrc_File Oct 28 06:23:19 you can make a simple xinitrc that just has the top line and that bottom line, but replace openbox with fluxbox or blackbox, or whichever you have installed Oct 28 06:27:03 sorry for one more stupid question...but the first line is xcompmgr -fF -I-.002 -O-.003 -D1 &? or export OOO_FORCE_DESKTOP=gnome Oct 28 06:32:42 #!/usr/bin/env bash-------> this is the first line Oct 28 06:32:50 and then exec fluxbox Oct 28 06:33:39 yes Oct 28 06:33:59 the #!/usr/bin/env bash line was what I meant by the first line Oct 28 06:49:21 @jpfau...its working perfectly..but my real problem still not solved...actually before fluxbox/blackbox i was running LXDE....and i cross compiled the QT-5.2 libraries...but when i am executing the application..it don't show any window Oct 28 06:49:27 can you tell me about this? Oct 28 06:49:44 does it give you any sort of errors? Oct 28 06:50:15 and when i tried to run the Qt application without any desktop enviornment (console only)..it worked but then i can not use the scree..i need to use it with SSH Oct 28 06:50:40 yeah for LXDE it said...failed to set graphics mode inappropriate ioctl for device Oct 28 06:51:07 but now for fluxbox and blackbox it is not saying anything...i can see he program is executed but i can not see any output Oct 28 06:51:34 hmm, sounds like it's trying to do something that isn't supported by the BBB, maybe something fancy with graphics, idk Oct 28 06:52:34 no...i m just executing a simple analog clock application Oct 28 06:53:16 Sorry, I don't know how to help beyond what I've already said Oct 28 06:53:22 without any desktop enviornment, it showed the analog clock but then i can not use the screen.i need to use SSH Oct 28 06:53:36 oh...okay ...really appreciate your help Oct 28 06:53:48 learned a new thing from you Oct 28 07:09:48 rao_, You need to start a graphical app from ssh console? Oct 28 07:10:15 (just wondering what "i can not use the screen.i need to use SSH" means) Oct 28 07:45:01 @MK_FG, i mean when i execute the QT graphical application from the terminal. then the screen hangs and i can not move mouse or even use the keyboard...then i use SSH to kill the application. But after killing application from SSH, i can not use keyboard and mouse again on the scree. So i need to use the SSH for interacting with the BBB. Or i need to restart the BBB for direct interaction. Oct 28 07:47:55 sounds like you're doing something wrong then Oct 28 07:49:06 are you starting the Qt apps as X11 apps or running them on the framebuffer? Oct 28 08:01:04 Anyone know stuff about https://github.com/rvfh/meta-ti/blob/master/recipes-kernel/linux/linux-mainline-3.2/beagle/0011-default-to-fifo-mode-5-for-old-musb-beagles.patch Oct 28 08:01:50 switched from fifo_mode 2 to fifo_mode 4 a while ago, but now it seems that 4 is bad as well Oct 28 08:07:58 @br..i have no idea about this thing..frambuffer and X11 Oct 28 08:08:12 can you tell me about it something Oct 28 08:25:22 hi Oct 28 08:25:28 lo Oct 28 08:30:42 Z Oct 28 08:31:49 @tbr..i studied about it and I am writing the application directly to the framebuffer using -platform linuxfb plugin as QT-5.2 doesn't support eglfs plugin. and eglfs supports X11 Oct 28 08:34:27 rao_: well if you bypass the x-server, no wonder that things go haywire Oct 28 08:36:43 any solution to this? Oct 28 08:39:58 yes, be consistent in what you do Oct 28 08:40:11 either go framebuffer or use Xorg Oct 28 08:41:21 quite a newbie here also with BBB, have a question regarding a problem faced with spidev with slow transfer rates with single byte transfers with SPI. Oct 28 08:42:48 what is "slow"? Oct 28 08:43:05 SPI is running at 16MHz on BBB, where byte transfer takes around 2-3 mS which is considerably large to drive an adafruit LCD Oct 28 08:43:35 then transfer more than one byte at a time Oct 28 08:43:43 tried burst transfers with nearly 3000 bytes at once which is very fast Oct 28 08:43:54 there you have it Oct 28 08:44:01 i need byte mode as the pixels to write are adressed Oct 28 08:44:18 write a whole line at a time Oct 28 08:44:38 anyone here today who knows about usb host? Oct 28 08:44:47 I know the words Oct 28 08:44:54 im trying to understand the problems a little more Oct 28 08:44:57 ask, dont ask to ask Oct 28 08:45:11 are they related to filtering capacitor and/or electrical noise? Oct 28 08:45:34 im thinking of try some experiments today with 3.8.13 kernel Oct 28 08:45:54 the thing is i want to use AdafruitGFX libraries and Adafruit LCD modules and dont want to modify the underlying code Oct 28 08:46:10 3.17.1 kernel fixes all usb host issues for me Oct 28 08:46:16 but no capemanager Oct 28 08:46:32 but why should a byte write takes 3 mS...? at 16MHz clock for SPI? Oct 28 08:46:39 how long before capemanager comes to 3.8.13? Oct 28 08:47:18 *3.17.1 Oct 28 08:48:02 but for QT only three plugins are available...linufx, minimal and offscree, Oct 28 08:49:00 av500: thank you for the reply, but the question is is it BBB related or arm related.. or am I doing something wrong here..? Oct 28 08:51:10 i used example code spidev_test.c from https://www.kernel.org/doc/Documentation/spi/spidev_test.c (not Quad SPI but an older version) Oct 28 08:55:13 The idea is to port Adafruit 2.2" LCD display ILI9340 to BBB (didn't see if someone already did it) using all the Adafruit LCD libs & graphics libs already available Oct 28 08:55:58 with only minor modifications so that it can be readily used by anyone Oct 28 08:58:13 anyone faced a similiar problem with SPI 'single byte' write taking nearly 3mS...(>8MHz SPi clock) any suggestions for improvement would be great... Oct 28 09:03:41 krsheshu: I guess it is the latency of making a single syscall and then setting up a single SPI transfer in the kernel Oct 28 09:03:53 again, why single byte writes? Oct 28 09:04:08 why not make writes to a backing buffer and then write that out fast? Oct 28 09:04:50 krsheshu: just for reference: a fast syscal takes about 10-20us, an average syscal is somewhere in the 100-200us region Oct 28 09:05:28 krsheshu: and this is just to get into the kernel, not doing much work Oct 28 09:05:53 krsheshu: any locks taken or memory access increase this many fold Oct 28 09:16:45 av500: it looks like if i do that way i need to modify the existing modules (which I dont want to take the pain, if there is an easy way) Oct 28 09:18:27 av500: writing single line once will also change the way how the animations are currently made in the LCD.. thats the issue Oct 28 09:20:49 ? Oct 28 09:21:59 KotH: do you mean a single ioctl call ? or something below this layer? (im not very experienced in internals to be frank) Oct 28 09:22:47 yes Oct 28 09:22:52 ioctl == syscall Oct 28 09:23:50 av500: thank you. so that means if i make a fast syscal i should get around 20us ? i use onyl one ioctl call Oct 28 09:23:58 lol Oct 28 09:24:04 you cannot choose how fast your syscall is Oct 28 09:24:11 :) Oct 28 09:24:18 syscall(....., DO_IT_FAST); Oct 28 09:24:32 +1 Oct 28 09:24:59 its controlled by kernel or ? can i set some priorities or something? Oct 28 09:25:04 no Oct 28 09:25:20 I would say, you cannot go much further from here without diving into the kernel Oct 28 09:25:25 into the spi driver Oct 28 09:25:33 adding some debug to see where time is spent Oct 28 09:25:44 maybe there is a way to reduce the latency Oct 28 09:25:44 learn to profile Oct 28 09:25:46 well... to make syscalls faster, you need to rewrite low level portions of the kernel Oct 28 09:25:57 its not the syscall Oct 28 09:25:58 its not this hard Oct 28 09:25:59 i think rewriting arduino code is faster Oct 28 09:26:01 its the SPI driver Oct 28 09:26:07 av500: that too Oct 28 09:26:41 basically, you can start having fun Oct 28 09:26:55 haha Oct 28 09:30:16 i think the spi LCDs are meant to be controlled from RTOSes, which I may have missed... Oct 28 09:30:24 nonsense Oct 28 09:30:33 SPI LCDs are controlled fine by any OS Oct 28 09:31:15 and, aren't there lots of showcases by now driving a spi lcd? Oct 28 09:31:24 IIRC even playing videa Oct 28 09:31:31 *video Oct 28 09:32:45 so why reinvent everything? Oct 28 09:32:46 https://www.youtube.com/watch?v=0C4lXej2H_I Oct 28 09:33:51 mdp: this video has not been done with putpixel(x,y,color) Oct 28 09:33:56 so please stop trolling Oct 28 09:34:09 oh, and good morning Oct 28 09:34:47 av500: awwwwww :-( Oct 28 09:34:57 understood, we have constraints that are insane here. continue then. Oct 28 09:35:47 mdp: hm, insane constraints or insanity contraints? if the latter, are they positive or negative? Oct 28 09:36:32 lost another customer..we'll never make any money at this :( Oct 28 09:37:20 but we kept the moral highground Oct 28 09:39:14 does that count as a legal high`? Oct 28 09:41:24 high would I know? Oct 28 09:47:34 mdp: why are you up so early? Oct 28 09:47:44 mdp: insomnia like mranostay? Oct 28 09:47:56 still a little off from .tw Oct 28 09:53:47 mdp: that's quite a bit off Oct 28 10:57:38 does the ti kernel support capemanager? Oct 28 11:01:11 which one? Oct 28 11:01:22 dunno Oct 28 11:01:27 --ti-kernel Oct 28 11:01:38 in the kernel updater script Oct 28 11:01:44 ill try it anyway :D Oct 28 11:01:55 its not like itll be any worse Oct 28 11:02:11 famous last words Oct 28 11:42:22 for a hobby project, i'd like to turn my beagleboard into a simple computer with screen and keyboard, but build it all into one case like an old arcade game. i don't want a gui, so it'll ideally just fit an old school 80x24 terminal. i'm new to the hardware scene, but i'd expect i'd need to buy some peripherals to give the board a screen + keyboard. any tips on what to look at first? Oct 28 11:47:07 wow beaglebone is so broken Oct 28 11:47:25 http://pastie.org/9680560 Oct 28 11:47:28 what the fuck Oct 28 11:48:56 ran out of space? Oct 28 11:49:03 maybe Oct 28 11:49:04 Moult: usb for keyboard Oct 28 11:49:12 im trying to remove _everything_ Oct 28 11:49:16 but its not going well Oct 28 11:49:21 buy an old VT100 for serial terminal Oct 28 11:49:37 as said, ignore emmc and use 8GB SD card Oct 28 11:49:47 if rpi can, so can you Oct 28 11:49:52 nah Oct 28 11:50:00 it needs to be vibration resistance Oct 28 11:50:02 av500: yep usb seems simple enough for keyboard Oct 28 11:50:04 *resistant Oct 28 11:50:07 av500: what about for screen? Oct 28 11:50:17 Moult: USB is broken too Oct 28 11:50:23 Moult: terminal? Oct 28 11:50:31 Laurenceb: ? Oct 28 11:50:36 nonsense Oct 28 11:50:46 usb host fails Oct 28 11:51:04 sigh Oct 28 11:51:22 im going to give it until the end of the week then ill literally set this thing on fire Oct 28 11:51:25 av500: yeah don't care about gui, so just terminal would be fine...although configuring font and colours would be nice Oct 28 11:51:35 Laurenceb: make sure to make a video of it Oct 28 11:51:48 yup Oct 28 11:51:50 Moult: then you need a better term than VT100 Oct 28 11:52:01 av500: yeah Oct 28 11:52:04 http://pastie.org/9680565 Oct 28 11:52:06 ok wtf Oct 28 11:52:08 why not a cheap HDMI monitor? Oct 28 11:52:13 how do i just remove all the shit?! Oct 28 11:52:13 av500: at a minimum i want to enjoy to play nethack :) Oct 28 11:52:29 Laurenceb: debian packaging Oct 28 11:52:33 I know nothing about it Oct 28 11:52:44 this is the default beaglebone.org flasher, WTF Oct 28 11:52:54 everything is broken, as i said Oct 28 11:53:09 ive yet to get a single BBB to even boot into a usable state Oct 28 11:53:17 after a week of trying full time Oct 28 11:53:40 these errors are during flashing? Oct 28 11:53:49 beaglebone.org build has a segfaulting python2.7 Oct 28 11:53:52 av500: actually, i might consider a vt100, got any links i can look at? Oct 28 11:53:56 ebay? Oct 28 11:54:08 av500: im ssh in and trying to fix python Oct 28 11:54:16 ah Oct 28 11:55:35 av500: well, what do i search for? vt100 gives me nothing Oct 28 11:55:47 does apt use python? Oct 28 11:55:51 well, you are late by a few decades :) Oct 28 11:55:56 it seems to be segfaulting Oct 28 11:56:37 hmf Oct 28 11:56:42 this is unfixable Oct 28 11:56:46 wtf Oct 28 11:57:03 can someone like my to a image that boots? Oct 28 11:57:07 and works Oct 28 11:57:12 *link me Oct 28 11:57:23 it all depends on the definition of 'working' Oct 28 11:57:24 as i cant even find one :-/ Oct 28 11:57:29 python runs Oct 28 11:57:42 as i need python to run the update_kernel.sh script Oct 28 11:57:51 beaglebone.org has broken python Oct 28 11:58:14 av500: surely there are modern simple cheap monitors which are functionally equivalent to a vt100? Oct 28 11:59:04 er no Oct 28 11:59:13 this is a classic catch22 Oct 28 11:59:15 much like steam engines went out of business Oct 28 11:59:17 its impossible to fix Oct 28 11:59:39 can you post this on the mailing list? Oct 28 11:59:45 hmm Oct 28 11:59:46 Laurenceb: so you want to change the kernel? that's not necessarily trivial and certainly error prone. Oct 28 11:59:46 with exact revision of image used? Oct 28 11:59:55 tbr: kernel update should work Oct 28 12:00:11 av500: from 3.8.13-x to x+1, sure :) Oct 28 12:00:13 it should not fail due to python Oct 28 12:00:21 Linux beaglebone 3.8.13-bone50 #1 SMP Tue May 13 13:24:52 UTC 2014 armv7l GNU/Linux Oct 28 12:00:33 i got the eMMC flasher from beaglebone.org Oct 28 12:00:39 av500: lame, so what should i look at? cheap hdmi monitors? Oct 28 12:00:50 default python is python2.7, and it segfaults Oct 28 12:01:15 http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2050601.m570.l1313.TR3.TRC2.A0.H0.Xserial+terminal&_nkw=serial+terminal&_sacat=0 Oct 28 12:01:34 not much indeed Oct 28 12:02:22 ok i have a plan Oct 28 12:02:29 use python2.6 Oct 28 12:02:44 http://www.ebay.com/sch/i.html?_odkw=&_osacat=162075&_from=R40&_trksid=p2045573.m570.l1313.TR10.TRC0.A0.H0.Xterminal&_nkw=terminal&_sacat=162075 Oct 28 12:02:59 has some Oct 28 12:03:49 hmm...2.7 have been around for so many years. going to 2.6 doesn't make sense. you can better look into the error you are getting Oct 28 12:04:19 wuhaha Oct 28 12:04:21 works Oct 28 12:08:49 and boots Oct 28 12:08:56 av500: do you know if the latest debian build on the bbb has X preinstalled? Oct 28 12:09:03 no sign of capemanager in the TI kernel :-/ Oct 28 12:09:11 is it possible to use the ADC? Oct 28 12:10:57 ask TI? Oct 28 12:11:11 (I'd expect so) Oct 28 12:19:54 hmm Oct 28 12:20:11 no iio in /sys/bus Oct 28 12:22:54 if there is no cape manager, then you need a proper DT preloaded Oct 28 12:24:46 what is a DT? Oct 28 12:27:10 device tree Oct 28 12:27:38 ah Oct 28 12:28:35 you need to tell the kernel which devices are there that need drivers loaded and be made available etc Oct 28 12:34:22 and than use overlay Oct 28 12:34:23 haha Oct 28 12:38:42 hmm Oct 28 12:38:54 im going to go back to the 3.8.13 kernel Oct 28 12:43:07 if i can work out how Oct 28 12:43:14 --kernel 3.8.13 fails Oct 28 13:09:23 Morning All. Oct 28 13:09:59 hi Oct 28 13:10:06 hmf Oct 28 13:10:13 ever get that emmc flashed? Oct 28 13:10:18 not usably Oct 28 13:10:23 still working on it now Oct 28 13:10:28 Aww - that sucks. Oct 28 13:10:32 atm i am trying to fix python Oct 28 13:10:39 python 2.7 segfaults Oct 28 13:10:50 with the beaglebone.org image Oct 28 13:11:12 Shouldn't that function out-of-the-box? :) Oct 28 13:11:34 it should, but this is beaghlebone we are talking about Oct 28 13:12:46 for some reason pip isnt running with python2.6 Oct 28 13:12:54 and i need pip to test gpio Oct 28 13:13:18 Setting up python2.7 (2.7.3-6+deb7u2) ... Oct 28 13:13:18 Segmentation fault Oct 28 13:13:21 argggggggggggg Oct 28 13:13:30 anyone here in the UK? Oct 28 13:13:42 you do not need pip for gpio really Oct 28 13:13:54 i know but it helps Oct 28 13:13:55 you can always tinker with /sys yourself and shell Oct 28 13:14:13 E: Sub-process /usr/bin/dpkg returned an error code (1) Oct 28 13:14:26 so in a week of trying ive only made negative progress Oct 28 13:14:50 anyone got any ideas how to fix this? Oct 28 13:15:05 is there another eMMC flasher image anywhere? Oct 28 13:15:18 other than the broken one form beaglebone.org? Oct 28 13:15:21 *from Oct 28 13:17:16 hmf Oct 28 13:17:44 pity they dont ship with debian Oct 28 13:17:49 or id buy a new board Oct 28 13:18:40 ? The element14 version of the beaglebone black ships with Debian. Oct 28 13:18:46 oh Oct 28 13:18:47 cool Oct 28 13:18:51 ill order some Oct 28 13:19:23 Linkage -> http://www.adafruit.com/products/1876?gclid=CNbL4_C3z8ECFRJp7Aod6xgAwg Oct 28 13:19:49 Debian Linux w/the 3.8.13-bone kernel - Specifically. Oct 28 13:21:27 if only they had an image Oct 28 13:22:28 as i cant seem to find a way to fix this mess Oct 28 13:23:06 You're saying that the version on here http://beagleboard.org/latest-images is borked? Oct 28 13:23:17 Has someone make work the Miniature WiFi (802.11b/g/n) for the BBB using the newest version of Angstrom kernel 3.8+ ? Oct 28 13:23:17 yes Oct 28 13:23:31 RangerGeek: python segfaults Oct 28 13:27:22 LaurenceB - you might try posting on the bbb adafruit forum as well to see if they have an image available. http://forums.adafruit.com/viewforum.php?f=49 Oct 28 13:27:37 ok Oct 28 13:27:54 i suspect this is fixable Oct 28 13:28:04 i managed this fix yesterday, but didnt make notes Oct 28 13:28:19 bricked my BBB last night and had to reflash Oct 28 13:29:19 http://pastie.org/9680737 Oct 28 13:34:45 looks like there's multiple images on this site as well toward the bottom - http://elinux.org/Beagleboard:BeagleBoneBlack_Debian Oct 28 13:36:17 Laurenceb: stupid question: do you have a serial cable for the debug-serial port?
