**** BEGIN LOGGING AT Fri Dec 18 02:59:59 2015 Dec 18 04:44:18 Hi all. First time joining a chat like this. Currently reading Exploring BeagleBone, so I will likely be asking some questions in the near future. Dec 18 05:07:57 There's a book for this?! Dec 18 06:15:43 wonder if most bone users are headless or head'ed Dec 18 06:33:57 does a tiny lcd count? Dec 18 06:43:14 both Dec 18 06:43:19 Humpelstilzchen: yeah! Dec 18 07:00:41 Humpelstilzchen: the I2C/SPI ones? Dec 18 07:00:57 trying to understand why the OpenGL stuff isn't used more Dec 18 07:50:22 ds2: i2c indeed Dec 18 07:54:34 for what I am looking at, that's headless Dec 18 08:30:44 hi Dec 18 08:30:59 * uuu slaps denix around a bit with a large fishbot Dec 18 08:31:30 * uuu slaps Vasco_O around a bit with a large fishbot Dec 18 14:03:02 Having trouble with Audio on BBB, why is it only supported under certain video resolutions, and is there a way around this Dec 18 14:04:16 * tbr suspects it to be a HDMI vs DVI thing Dec 18 14:04:38 edid Dec 18 14:04:51 oh no .. audio is to do with clocks and the framer iirc Dec 18 14:05:12 you can use audio via mcasp if you need an alternative Dec 18 14:05:23 or usb is probably cheap-/easiest Dec 18 14:05:47 Ok, via MCASP, but what if i want to use the onboard eMMc, won't there be conflicts? Dec 18 14:06:17 I think there are two mcasps .. you'd need to check the pinmux tables.. and/or zmatt's spreadsheet Dec 18 14:09:08 I forget where that's posted .. unless zmatt is about .. Dec 18 14:11:05 looks like mcasp0 is conflicting with LCD lines, possibly mcasp1? Dec 18 14:11:31 lcd are used for hdmi video :/ just beware! Dec 18 14:12:22 I am aware, I am trying to use the onboard HDMI and create my own audio cape, Dec 18 14:12:54 ut it appears as though there are only limited video resolutions that can support audio, why that is idk Dec 18 14:12:55 ds2: Our will be headless with a tiny OLED. Dec 18 14:14:48 Does anyone have experience running video with Circuit Co's audio cape? Dec 18 14:34:49 Dtown .. is it 'ok' for use with the Black variant?! :) just checking! Dec 18 14:42:37 rcn-ee .. are there any up-to-date instructions for opengl-es and sgx about? Dec 18 14:43:09 veremit, black variant? Dec 18 14:43:24 veremit, i cleaned up: http://elinux.org/BeagleBoardDebian#SGX_BeagleBone.2FBeagleBone_Black Dec 18 14:43:27 beaglebone-black .. some capes aren't 'black' compatible because of the emmc Dec 18 14:43:35 rcn-ee .. great stuff :) Dec 18 14:43:41 still don't have the new drivers working yet.. Dec 18 14:43:46 any progress on orange-pi yet?! ;P Dec 18 14:43:52 but i no longer mention the 3.14.x kernel.. Dec 18 14:44:14 rcn-ee: ok well that's better than 3.8 for sure :D Dec 18 14:44:23 if that ever worked! Dec 18 14:44:49 veremit, got side tracked... kmscube on imx6/etnaviv, it's fun to see opengl es working. ;) Dec 18 14:44:59 oh yea? Dec 18 14:45:17 I just plugged my wand-dual up to check debian networking :/ Dec 18 14:45:38 someone was having trouble with wifi configured in /etc/network/interfaces and auto-rfkill ;/ Dec 18 14:45:58 who's bright idea that was .... ! Dec 18 14:46:36 i got a couple about that.. rfkill, anyway to have it 'remember' what setting you had.. Dec 18 14:47:27 yeeessssss Dec 18 14:49:44 (if only they didn't block wifi at work, i could actually test the wifi settings...) Dec 18 14:50:02 really.. bugger. Dec 18 14:51:12 usually get about 30-60 seconds with a new wifi/mac address before they get hit by the "disconnect packet of death" from the secure access points.. Dec 18 14:51:40 ouch bastards Dec 18 14:52:38 use to sneak on channel 13, but that doesn't always work either. ;) Dec 18 14:53:53 EM-cell/box ;) Dec 18 15:23:20 rcn-ee, any updates on the X15? Dec 18 15:24:20 bgamari, haven't heard much, gerald hasn't been on the weekly call these last couple of weeks.. i know they spun another board to get thru fcc, not sure on the results yet.. Dec 18 15:24:21 * bgamari has a project for a client which involves lots of compilation Dec 18 15:24:38 it would be great if I didn't need to do this on a BBB Dec 18 15:25:00 hmm Dec 18 15:25:04 sad Dec 18 15:25:45 bgamari, till they come out, rent one of these: https://www.scaleway.com/ (3euros a month) ;) Dec 18 15:25:51 rcn-ee, I suppose in the best case it will be a month or two before boards are available, eh? Dec 18 15:26:03 yeah last i heard after xmas.. Dec 18 15:26:05 I would love to! Dec 18 15:26:14 unfortunately it seems they ran out of hardware Dec 18 15:26:19 * bgamari has been waiting in line for an account Dec 18 15:26:56 really? that explains why i can't get a 2nd node up and running.. Dec 18 15:27:08 https://blog.scaleway.com/2015/11/03/scaleway-is-growing-too-fast-out-of-stock/ Dec 18 15:28:19 rcn-ee: Bit sad on the x15, but thanks for the update. Been waiting for it for a while Dec 18 15:28:30 rcn-ee: what's the hold up, certification somewhere? Dec 18 15:30:04 Spidler, we were all ready for a Nov, launch... But all bb.org products go thru fcc testing.. Well taht friday before... it failed.. badly... We tuned a few thigns in u-boot/kernel, to quiet a few things down.. but in the end, a pcb redesign was needed (hdmi/power coupling..) Dec 18 15:30:46 ouch Dec 18 15:31:01 but on the software side we found more bugs... so the 'default' image has a lot more fixes. ;) Dec 18 15:32:08 rcn-ee: ouch. Right, I'm quite happy about that testing, as we have to go through CE marking of stuff here as well. Dec 18 15:32:22 rcn-ee: Better you get that "pleasure" than having to fix something afterwards. Dec 18 15:32:47 A bit sad that I couldn't get one for xmas though, was hoping that it'd turn up to be my first "proper" ARM-desktop machine. Dec 18 16:30:07 rcn-ee, did you turn off anything to pass FCC tests that we power users would want to turn back on? Dec 18 16:31:30 Well my first kernel module didn't appear to screw the pooch, as it were. \o/ Dec 18 16:32:56 rcn-ee, the HDMI framer on an uncased BBB is known to our lab to dramatically reduce the quality of GPS for about 3 meters around, so we're familiar with turning things off to reduce noise. Dec 18 16:33:54 ecdhe: How do you turn off that easily? Dec 18 16:34:40 Spidler, with a device tree overlay that runs at boot. Dec 18 16:34:50 Ah. Okay Dec 18 16:35:09 I thought the overlay mechanism was replaced? Dec 18 16:35:16 I'll have to look at that further. We run ours headless so Dec 18 16:35:38 Ragnorok, in what distro was it replaced, and what was it replaced with? Dec 18 16:35:48 We use debian. Dec 18 16:36:16 For some reason I think 4.1.13 kernel loads it "native", and I don't know what it was replaced with because I haven't researched it enough. Dec 18 16:36:46 Spidler, https://learn.adafruit.com/setting-up-io-python-library-on-beaglebone-black/spi Dec 18 16:37:01 There's a boot flag to turn it off. Dec 18 16:37:23 Ah. In uEnv.txt. That sounds familiar. Dec 18 16:46:53 ecdhe, yeah the hdmi makes lots of noise on the bbb... Dec 18 16:47:24 rcn-ee, can I ask what kind of tweaks you'd make to a kernel to pass FCC? Dec 18 16:48:07 ecdhe, well it didn't pass yet that i know offf.. on the x15, we had the lcd panel pins, active... so disablign that helped.. Dec 18 17:36:44 Does anyone know how to enable the adafruit-bbio python library to drive the USR leds? Dec 18 17:37:37 strace python USR.py shows me that the call is failing: open("/sys/class/gpio/export", O_WRONLY) = 3 Dec 18 17:37:44 write(3, "53", 2) = -1 EBUSY (Device or resource busy) Dec 18 17:40:07 This call is analogous to `echo 53 > /sys/class/gpio/export' Dec 18 17:40:54 But I don't know what I need to turn off to resolve the "Device or resource busy" problem. Dec 18 17:45:06 rcn-ee: i didn't quite get your neo answer... Dec 18 17:45:23 are you going to add any notes to the udoo page? Dec 18 17:45:59 nerdboy, it's on my list. ;) the box is right in front of me. ;) Dec 18 17:47:26 it'll be a seperate page due to a different u-boot... and a much newer kernel.. Dec 18 17:57:45 Hi, Can I power the device from DC barrel as wel as USB at the same time? I'm afraid of damaging the device. Dec 18 17:58:14 I'm talking about the Beaglebone Black Dec 18 17:58:24 Benny_, yes/no... you can plug in both... but no, you can't 'live' switch between the two sources... Dec 18 17:58:51 (it'll shutdown) Dec 18 17:59:24 So I'll have to insert the barrel jacket first if that is my desired power source? Dec 18 17:59:32 yeap Dec 18 17:59:39 cool, thanks. Dec 18 18:31:37 test Dec 18 18:32:41 anyone online? Dec 18 18:35:26 Guest19871: yes. Dec 18 18:35:40 Guest19871: in general, just go ahead and start asking questions Dec 18 18:40:07 So whats the best way to connect to the black? I have an ftdi chip and a usb cable Dec 18 18:42:54 ssh? Dec 18 18:43:15 hardware wise though? Its not networked yet Dec 18 18:44:42 Guest5: there's a serial header on the board you should be able to plug it into Dec 18 18:45:07 Okay, thats what I'll do, thanks! Dec 18 18:45:43 * vagrantc digs up a page about this stuff Dec 18 18:45:58 Guest5: http://www.elinux.org/Beagleboard:BeagleBone_Black_Serial Dec 18 18:46:57 okay, thanks! Now, I just plugged it in to my mac and a boot drive showed up. Can I connect over this or do I need to use the debug port? Also, can I write new images to the boot drive directly? Dec 18 18:47:12 Sorry, a lot of questions. I just got this! Dec 18 18:48:02 it's probably just showing you one partition on the machine, not the whole eMMC device Dec 18 18:49:23 Okay, and I was just able to open a screen session to it as well. It showed up as a tty.modem Dec 18 18:53:37 yes, you should get a composite serial, with mass storage, networking too Dec 18 18:53:48 but these can be tricksy sometimes Dec 18 18:54:08 you can ssh over the usb link :) Dec 18 18:54:11 but serial works Dec 18 18:54:45 Debug serial via the header can be helpful to troubleshoot boot problems Dec 18 19:10:21 Hi Dec 18 19:10:26 Sorry, i have a problem Dec 18 19:10:33 i can't install the drivers for windows Dec 18 19:10:48 i have windows 10, that's the problem, right? Dec 18 19:12:07 I thought there were new, signed drivers for windows Dec 18 19:12:49 W10 is a problem, but it may not be your driver problem. (wink) Afaik a BBlack at least can work in W10. I think a co-worker has that setup. Dec 18 19:16:13 Can i get it? Dec 18 19:16:21 where can i find it? Dec 18 19:17:11 When i tried to install the drivers, in the window says that i cant just install it Dec 18 19:17:20 idk why Dec 18 19:17:22 :( Dec 18 19:17:46 you've tried this? http://beagleboard.org/getting-started#step2 Dec 18 19:17:53 Sent an email. We'll see what comes back. Dec 18 19:17:54 yes Dec 18 19:19:42 thank you Dec 18 19:44:55 zmatt: do you have a way to boot from the network? i'd like to debug my buidls without having to flash each time. Dec 18 19:45:08 zmatt, or anyone else... Dec 18 19:49:37 e.g., if you configure boot mode for emac1, how does that work? what network protocol/setup is required for emac1 boot? Dec 18 19:58:16 yates: you could put rootfs on NFS Dec 18 19:59:36 Ragnorok: what is your issue with BBB in win10? mine works as it should Dec 18 19:59:47 installed the drivers as it said Dec 18 20:04:16 felon-: I don't have an issue, as I don't use w10. Looks like Jfrmz, who is having the issue, dropped off. (shrug) Dec 18 20:22:28 ah thanks Ragnorok Dec 18 20:23:55 rcn-ee: working on PyBBIO support on 4.1 - just noticed that the pip build on there is broken because it depends on an older version of the requests package Dec 18 20:24:44 is omap-image-builder/target/chroot/beagleboard.org-jessie.sh the place to push a fix for that? Dec 18 20:25:23 alexanderhiam, yeap... (wheezy will always be 3.8) so fix in jessie. ;) Dec 18 20:31:41 cool, pull request should be coming soon... Dec 18 20:46:26 alexanderhiam, remeber, if you use the new dtc, you'll probally have to move the "install_git_repos" before install_pip_pkgs... Dec 18 20:57:45 rcn-ee: is the old dtc replaced in install_git_repos? Dec 18 21:00:33 yeap... and use /usr/local/bin/dtc (wheezy/jessie, we still support running the "3.8" so dtc-3.8 gets /usr/bin/dtc) Dec 18 21:01:05 With stretch, i'll drop dtc-3.8 and /usr/bin/dtc will point to the dtc-4.1+... Dec 18 21:08:45 rcn-ee: oh, you know, I think I stopped building overlays at install time and just copy over dtbos, so I may not care... Dec 18 21:09:39 if I need different overlays for 3.8 and 4.1 I can just have two directories of dtbos and detect that at install time Dec 18 21:10:12 oh, yeah then don't worry about that.. ;) Dec 18 21:10:45 btw, the "4.1" dtbo's should be 100% compatible with "4.4" (well so far it is) Dec 18 21:12:55 awesome. And the only thing that's changed on that front between 3.8 and 4.1 is the compiler? i.e. my 3.8 overlays should be fine as is? Or has there been any changes to the drivers I'll need to take into account? Dec 18 21:13:28 * alexanderhiam needs to get caught up on all the 4.1 changes Dec 18 21:29:01 alexanderhiam, compiler, &usartX=&usart(X-1) & &gpioX=&gpio(X-1)... about 99% of the rest got ported... Dec 18 21:50:07 rcn-ee: actually, not sure the best way to fix pip - the debian package is broken (well, I guess fixing that would be the /best/ thing to do...) - does it make sense to remove it from the deb list and wget and run the pip bootstrap script in chroot.sh? Dec 18 21:52:37 alexanderhiam, what version works? could backport it from stretch.. Dec 18 21:54:23 oh my... 5.6 came out in 2014... Dec 18 21:57:11 yeah... 1.5.6-5 in jessie repo and 1.5.6-7 in stretch Dec 18 21:57:53 yeah, so i double 1.5.6-7 will fix your problem... Dec 18 21:58:03 i guess we might as well do: https://pip.pypa.io/en/stable/installing/ Dec 18 21:58:32 yeah, it seems like that script is the way to go Dec 18 21:58:33 can we define a speicfic version of pip with "pip install -U pip" Dec 18 21:59:25 perhaps if the current pip worked at all :P Dec 18 22:00:10 nope... it pullse down 7.1.2.. ;) Dec 18 22:01:27 Per the comments in http://bugs.elinux.org/issues/159, the Debian 8.2 image on the Latest Images page is wrong. Is there a way to get this page updated to the correct link? Dec 18 22:01:39 looks like 'pip install -Iv package==version' works, but the package needs to be uninstalled first Dec 18 22:03:15 ewrtrew, jkrinder's not on irc today either. he's got a few week old newborn at home, so he's on randomoly.. Dec 18 22:04:11 so remove pip from the deb list and run get-pip.py in target/chroot/beagleboard.org-jessie.sh? Dec 18 22:04:39 alexanderhiam, that's what i'm thinking... just making the change asap, so i can fire off a build. ;) Dec 18 22:04:58 Well, that is great news! I can imagine he is on only sporadically, and likely at strange hours of the night too! ;-) Can someone who has his contact information let him know about the issue and ask him to correct the link when he has a chance? Dec 18 22:06:05 rcn-ee: so many configs... any objection to doing an `apt-get remove python-pip` before get-pip.py in beagleboard.org-jessie.sh? :P Dec 18 22:06:40 alexanderhiam, we should be fine, on my x86, sudo python get-pip.py stuck it in /usr/local/bin/pip ;) Dec 18 22:06:48 Anyone? Dec 18 22:06:56 ah, nice Dec 18 22:09:34 alexanderhiam, just pushed this: https://github.com/RobertCNelson/omap-image-builder/commit/d15772eea2378a5e6389eac844d111469164ae90 Dec 18 22:09:44 it's now running on the farm: http://rcn-ee.homeip.net:8080/job/omap-image-builder_testrun/18/console Dec 18 22:09:53 so hopefully your package just installs now ;) Dec 18 22:10:20 you beat me to it! Dec 18 22:10:56 rcn-ee: interestingly PyBBIO is still on there, so it seems like that pip version works in the chroot... Dec 18 22:11:22 but it doesn't work as normal user? Dec 18 22:11:28 yeah Dec 18 22:11:35 if you do a "sudo su" Dec 18 22:11:38 and then try it? Dec 18 22:11:47 chroot runs as pure root... Dec 18 22:12:19 prehaps /sbin/adulterate is what you want? Dec 18 22:12:21 oh no, sorry, I'm running as root Dec 18 22:14:13 this is the error fwiw: http://pastebin.com/EMtJMJpk Dec 18 22:16:41 oh, get-pip.py also uninstalls any old versions Dec 18 22:51:08 alexanderhiam, it looks like it's working.. Dec 18 23:08:58 hey there everyone. I have a project using a BBB where we don't need all the connectors stuffed, and we use a different bootup resistor configuration. Is there a way to order BBBs with some light customizations? Would 100s to 1000s be enough to justify it? Dec 18 23:09:43 Note: i'm not askign for a board rev, just a stuffing rev. Dec 18 23:15:10 Nedlinpopo : you should get in touch with circuitco Dec 18 23:15:56 okay, will do. Is there someone in particular who i shoudl talk to there (or here)? Dec 18 23:37:47 there - I don't know who Dec 18 23:42:04 rcn .. damnit Dec 18 23:43:00 zmatt: in your main.S, i see a "1:" at the beginning of a few assembler lines. what the heck is that? Dec 18 23:43:32 does it have something to do with an ipblock? Dec 18 23:50:36 if there's plural, definitely not a label... Dec 19 01:42:03 yeah, it looks like a label, but it can't be Dec 19 02:18:29 wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee first assembly level patch for an android app and it works! Dec 19 02:18:33 userland sucks Dec 19 02:43:09 hm, no rcn... Dec 19 02:44:21 non -ti kernels (up to and including 4.4-rc5-bone0) still have broken lcdc pixel clock calculation **** ENDING LOGGING AT Sat Dec 19 02:59:58 2015
