**** BEGIN LOGGING AT Tue Feb 17 02:59:58 2015 Feb 17 04:40:51 Hello Feb 17 04:57:07 Cool, got it working via SSH although my display was working it's not now. woot. Feb 17 07:06:06 hmz, I don't think you need JTAG to do PRU debugging, it can be single-stepped from the cortex-a8 via pru's memory-mapped registers Feb 17 07:07:26 (in fact, jtag debugging will just do exactly the same but via DAP, the PRUs don't have a JTAG TAP) Feb 17 07:12:02 i found dumping things to memory more then sufficient Feb 17 07:12:47 things on the PRU don't often make sense to single step as the PRU is suppose to respond to or generate signals in real time Feb 17 07:13:09 true Feb 17 07:14:36 real-time trace to ETB would be useful, but I don't think they support that Feb 17 07:33:57 also... only 9 MB/s ? that's much less than I'd expect PRU to be capable of Feb 17 07:37:03 ds2: are you using EDMA to get data out of PRUSS local memory or are you making the PRU cores write directly to non-local RAM ? Feb 17 07:38:10 hi, I got a new bbb, and want to test under mac yosemite. I've got the drivers installed, but sometimes my mac just freeze and force me to reboot, anyone share the same experience? Feb 17 07:38:23 zmatt: neither Feb 17 07:38:49 ? what are you doing with the incoming data then? Feb 17 07:38:53 the problem is it needs to do processing Feb 17 07:39:09 a 27MHz inbound data stream means you have about 6-7 instructions per clock Feb 17 07:39:26 being async means you have to look for edges so that leaves you with about 3 intructions per clock tick Feb 17 07:39:44 interrupt arm and have the arm pull data. no reason this can't be DMA'ed but that's another project Feb 17 07:40:30 no clock signal available to use the parallel capture feature? Feb 17 07:40:36 there is Feb 17 07:40:42 the parallel capture is just a latch Feb 17 07:40:49 you still need to look for edges Feb 17 07:42:56 any help pls? Feb 17 07:44:56 hmm, I see now, looking at the diagram... that design doesn't look very convenient (plus resynchronizing the clock is still the bottleneck, and I hope they didn't actually implement it the way they drew it in figure 4-9 ) Feb 17 07:46:06 as far as I can tell, they did Feb 17 07:46:27 they drew only a single flop to resync the data... one flop does not make a resynchronizer Feb 17 07:46:43 plus resyncing data and clock independently is a Bad Idea (tm) Feb 17 07:47:04 the other limitation is other accesses slow down the PRU. the ARM accesses throws in an extra click every now and then :( Feb 17 07:47:46 since the data flop can go metastable and then you'll get your clock pulse visible in register while the data is bogus Feb 17 07:48:14 hmm, is there no priority config for the pruss interconnect? Feb 17 07:48:35 I vaguely recall having seen something like that Feb 17 07:49:48 only between the PRUs Feb 17 07:50:38 I suspect the R31 register itself is a flipflop to give it 2 Feb 17 07:50:40 ah, there is such a register, but they omitted it from the current TRM Feb 17 07:50:51 there is? Feb 17 07:51:00 what docs are you using? Feb 17 07:51:32 it's in rev C of the TRM (spruh73c) Feb 17 07:51:51 section 4.9.1.10 SCRP register Feb 17 07:51:57 it's ... not very informative though Feb 17 07:55:39 i was looking on the seperate pru doc Feb 17 07:55:43 dl'ing rec v Feb 17 07:55:45 rev C Feb 17 07:56:27 there are three useful docs... the separate pru doc (do get the latest version), the latest TRM (separate doc got reintegrated, but not quite the same content), and the old rev C doc (again not quite same content) Feb 17 07:59:24 hmmm that reg may get better transfer rates Feb 17 07:59:43 if it turns out I need color, I'll look more into it Feb 17 08:00:25 right now i am dropping color at the PRU as the later consumers will convert things back to mono Feb 17 08:00:57 * zmatt is pondering what those 18 "elements" might be Feb 17 08:02:08 especially since priority is afaik configured per initiator, not per target... a PRU core might perhaps count for 5 initiators or so (if read and write are considered separate), but still... Feb 17 08:02:25 evening Feb 17 08:02:35 morning Feb 17 08:03:47 well my not so exciting day was getting my board cleaing tank running happily again Feb 17 08:03:53 maybe EDMA and ARM? Feb 17 08:04:11 both go through the same L4 port Feb 17 08:04:54 the L4HS (aka L4F) has only a single initiator port Feb 17 08:07:04 there's also the bridge port to pruss0 (which isn't present on the am335x but probably still included in that register) Feb 17 08:08:00 but still I don't see 18 initiators happening... maybe the prioritization is (also) based on target after all, dunno Feb 17 08:08:09 they should have fucking labeled those bitfields :P Feb 17 08:19:21 I want some information regarding this BBB Feb 17 08:19:41 Ping me Feb 17 08:20:06 Hello Feb 17 08:20:17 hi Feb 17 08:20:22 CTCP PING reply from VIJAY: 1.144 seconds Feb 17 08:20:23 there ya go Feb 17 08:20:41 I want some info about Beagle board Feb 17 08:20:42 anyhow, I'm off for now, later all Feb 17 08:20:57 k Feb 17 08:20:59 VIJAY: beagleboard.org Feb 17 08:22:00 hi Feb 17 08:22:19 I want info about Beage baord Feb 17 08:22:42 I want info about Beage board Feb 17 08:22:47 ping me Feb 17 08:23:33 nobody will ping you Feb 17 08:23:38 read beagleboard.org Feb 17 08:24:00 Y? Feb 17 08:24:01 or ask specific questions here Feb 17 08:24:09 ok.thanks Feb 17 08:24:10 or get kicked Feb 17 08:24:15 for insulting the channel Feb 17 08:24:37 How can i create file system in BBB? Feb 17 08:24:46 mkfs Feb 17 08:25:00 as on every other linux too Feb 17 08:25:08 if you use a linux of course Feb 17 08:27:17 yes Feb 17 08:27:52 alright Feb 17 08:27:58 i want the process to make & load on BBB Feb 17 08:28:11 read beagleboard.org Feb 17 08:28:15 its all explained there Feb 17 08:28:41 In this beagleboard.org, which block? Feb 17 08:28:50 getting started Feb 17 08:28:53 ok Feb 17 09:16:42 [kernel] ketul93 opened pull request #100: Solved Issues with some ISPs. (master...master) http://git.io/NbUY Feb 17 12:37:27 Hello, is someone here? Feb 17 12:40:35 nope Feb 17 12:40:43 no, all gone for winter vacation Feb 17 12:53:09 hmm, ok. And someone knows how to reload a plugued sdcard with system commands? Feb 17 12:53:30 "reload"? Feb 17 12:54:42 systemctl reload /dev/mmcblk0p1 Failed to issue method call: Job type reload is not applicable for unit dev-mmcblk0p1.device. Feb 17 12:56:15 the sdcard can't be unmounted because is on use and systemctl stop or reload don't work Feb 17 13:06:24 HeXtor: are you booting from the sd-card or from emmc? Feb 17 13:10:52 emmc Feb 17 13:12:50 you think that this can work? echo 1 | sudo tee /sys/bus/pci/rescan Feb 17 13:14:20 all it should take is to unmount the sd card partitions and then reinsert the card Feb 17 13:14:37 but it will also depend on the kernel/distro you are running Feb 17 13:21:16 i am running amstrong Feb 17 13:22:51 and sorry, i think that i am booting from sdcard with uEnv.txt Feb 17 13:27:05 if you are booting from sdcard then you can't switch the card Feb 17 13:27:33 or rather not as long as you are accessing it, and that's a given as long as your rootfs is on it Feb 17 13:31:36 ok, thx alot for the help @tbr Feb 17 13:32:08 you can only remount it ro Feb 17 14:12:00 Hi, which of the SPI0-D* is the MISO-input? Feb 17 14:13:22 SPIO-D1? Feb 17 14:20:34 anates: On the BBB? SPI0_D0 is MISO. Feb 17 14:21:39 Ok, thanks! Feb 17 14:22:40 If I want to connect a device with the BBB which should be able to play both master and slave (aka send data on its own without having to wait for the master), do I need two different SPI-connections? Feb 17 14:23:02 If yes, how do I tell the BBB that it should be master only on one connection? Feb 17 14:30:14 Hi Feb 17 14:30:20 anates: linux doesn't work as a slave; it can only be master Feb 17 14:32:53 for starterware project is there any alternative to start working on it instead setting it up ?? Feb 17 14:34:45 @jackmitchell: I.e. I have to set up a notifier, if a pin goes on high there is new data to fetch? Feb 17 14:35:38 anates: that's one way of doing it, I just know that Linux can't currently act as an SPI slave device; only master Feb 17 14:35:58 so you have to devise a way round it if that's how you want to do it Feb 17 14:38:51 The thing is, on my cape is another processor, which gets information from the BBB, handles it, awaits data from sensors, and then sends the data back. Therefore I wanted to use another SPI connection as master Feb 17 16:46:12 hello Feb 17 16:46:24 i just bought a bb black Feb 17 16:46:52 i installed drivers for windows 7 (nothing really happened) and i tried to connect to its IP address without much success Feb 17 16:50:58 i'm also wondering which firmware image to download Feb 17 16:51:12 there's one that says it's recommended Feb 17 16:51:19 and that doesn't flash the emmc Feb 17 16:56:06 "use the provided sd card". mine didn't come with one, i think Feb 17 18:28:16 anyone using MCP2515 Can bus stuff? Feb 17 19:10:27 Hi, I had my ralink USB wifi adapter (uwn100) working with the latest Debian image Feb 17 19:11:19 after I upgraded the kernel with "cd /opt/scripts/tools/ git pull sudo ./update_kernel.sh sudo reboot" it's not showing up anymore Feb 17 19:11:33 the usb device is, but "ra0" won't show up with iwconfig Feb 17 19:22:53 sounds like you don't have the driver for the new kernel Feb 17 19:23:38 you mean the mt7601 driver? (that's the one for uwn100) Feb 17 19:27:54 ah you're right Feb 17 20:02:03 Auke, the mt7601 is a seperate install: http://elinux.org/Beagleboard:Capes_3.8_to_3.14#mt7601u Feb 17 20:12:29 anyone knows where &gpio4 is? Feb 17 20:13:52 searched everything but can only find it till gpio3 ?? Feb 17 20:14:12 once you have used a micro sd card to install new firmware, can you use it as storage for the device? Feb 17 20:15:14 <_av500_> talin_: yes, you could Feb 17 20:15:23 great, thank you Feb 17 20:15:47 i think maybe i am flashing my emmc now Feb 17 20:16:22 i held the button close to the micro sd card down and powered it until they lit all of them at the same time Feb 17 20:16:32 now they are blinking randomly, so i'm guessing it's being installed Feb 17 20:17:30 <_av500_> yes Feb 17 20:27:53 Howdy, so I installed the debian emmc flasher to the SD card Feb 17 20:28:01 is there any indicator to progress? Feb 17 20:28:35 right now its the farthest left LED lit solid, 2nd one is kind of blinking, 3rd is empty, 4th is blinking rapidly (activity?) Feb 17 20:29:06 <_av500_> it takes a while Feb 17 20:29:14 <_av500_> at the end all should be solid or so Feb 17 20:29:46 so no other indicator, and i dont have to type anything in the shell? Feb 17 20:29:53 dunno if that is still the case on the latest images Feb 17 20:30:27 <_av500_> you dont have to type anything Feb 17 20:30:34 <_av500_> flasher flashes automatically Feb 17 20:30:35 ok Feb 17 20:31:03 trying to build uboot for the beaglebone black, does anyone know why there is not a config for the am335x ? Feb 17 20:31:32 <_av500_> there is Feb 17 20:31:39 <_av500_> in mainline uboot Feb 17 20:31:48 <_av500_> it was there two years ago Feb 17 20:31:52 <_av500_> im sure nobody removed it Feb 17 20:34:21 I got the uboot from https://github.com/beagleboard/u-boot and it looks like boards.cfg hasn't been updated in 4 years Feb 17 20:34:42 sounds like wrong repo Feb 17 20:34:45 use upstream Feb 17 20:37:37 Are there emulators for BBB? Like NES? I saw the SNES distribution Feb 17 20:37:58 and oddly enough when i google BeagleBone NES i get the snes distro :| Feb 17 20:47:34 that was quick lol Feb 17 20:47:40 took about 15 minutes Feb 17 20:53:46 tbr thanks, there is a config in the uboot at ftp://ftp.denx.de/pub/u-boot/ for the beaglebone Feb 17 21:15:12 hmm, i have installed the latest debian for my bb black Feb 17 21:15:27 i still can not see it in windows 7 after having installed the usb driver Feb 17 21:15:49 i changed my IP to 192.168.7.3 and tried to connect to it on 192.168.7.2, but no contact Feb 17 21:16:07 any tips? Feb 17 21:16:26 tried to connect to it using my browser Feb 17 21:18:13 <_av500_> can you connect it with ethernet? Feb 17 21:18:25 with SSH? Feb 17 21:20:24 <_av500_> yes Feb 17 21:21:02 hmm, now it works Feb 17 21:21:15 <_av500_> good Feb 17 21:21:22 cheer. why, i do not know Feb 17 21:27:04 is it possible to run jessie from a sd card? Feb 17 21:27:12 (without flashing it to the BBB) Feb 17 21:29:49 Auke, yes... if you look and read: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Jessie_Snapshot you'll see it.. Feb 17 21:30:38 oh ffs Feb 17 21:30:39 sorry Feb 17 21:30:46 was searching on the wrong page Feb 17 21:33:09 thanks! Feb 17 21:39:47 how do you guys normally code on a bbb? ssh into it and edit code with a fancy coding environment, or do you mount its filesystem with sshfs and work from the outside? Feb 17 21:40:02 c++ development Feb 17 21:43:18 vi/vim? Feb 17 21:46:25 i tried to install emacs, but my filesystem is full, it seems Feb 17 21:46:35 i have a micro sd card, but it's not mounted, it seems Feb 17 21:47:04 i just installed debian on it Feb 17 21:47:27 i replaced lxde with fluxbox Feb 17 21:47:34 try "apt-get clean" Feb 17 21:47:58 can i setup a swap partition on an SD card? Feb 17 21:48:37 tholm: hmm, didn't do much Feb 17 21:50:55 talin_, if you used a *.img, just follow: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Expanding_File_System_Partition_On_A_microSD Feb 17 21:51:38 rcn-ee: thank you, that looks less painful than i feared :) Feb 17 21:52:12 it's only painful, if you only have the 2GB eMMC and that's what your using.. Otherwise we tired to make everything easy. ;) Feb 17 21:55:22 2GB eMMC is enough for me. I only use 90MB :P Feb 17 21:55:51 with the 'full' lxde image?... Feb 17 21:56:20 nope, with nothing :) Feb 17 22:01:58 rcn-ee: i guess it takes a while to reboot after running grow_partition Feb 17 22:04:09 I want a BeagleBoard X15!!!! Cortex A15 and C66x are lovely monsters :) Feb 17 22:40:26 X15? Nary I've heard of that? Are you planning on using one of the keystone processors for it? :D Feb 17 22:41:46 GenTooMan, it's die is cut from the dra7xx line... Feb 17 23:11:03 Ugh I'm going crazy Feb 17 23:11:23 is it impossible to get the Chipsee 7 inch expansion to work with Wheezy Feb 17 23:11:25 ? Feb 17 23:12:37 <_av500_> why should it be impossible? Feb 17 23:13:58 Auke, it works if you use the 3.14.x kernel: spcecifing this dtb: http://elinux.org/Beagleboard:Capes_3.8_to_3.14#Chipsee_bbb-exp-c Feb 17 23:14:00 well I've been trying for a couple of weeks now, and I'm just too big of an idiot it would seem Feb 17 23:14:09 also read the note about the xorg fb size. Feb 17 23:14:22 When I try to do that, I get the message that he can't find the package Feb 17 23:14:49 "find what package"? Feb 17 23:15:07 sudo apt-get install linux-image-3.14.26-ti-r41 gives the error Feb 17 23:15:23 Ehm I'll try it again, and post the error Feb 17 23:16:05 use: sudo apt-get install linux-image-3.14.33-ti-r50 Feb 17 23:16:37 i don't keep every version in the repo..

Feb 17 23:19:50 i set the time zone O_o Feb 17 23:20:04 did you set "today's" date? Feb 17 23:20:23 * Milenko coughs Feb 17 23:20:37 i set... last years date -_- Feb 17 23:20:41 sudo ntpdate pool.ntp.org Feb 17 23:21:06 The certificate on rcn-ee.net is only good for a year. (August 2015).. Feb 17 23:23:15 Hmm still not working unfortunately Feb 17 23:24:01 Could it be that the problem is that I'm on 3.8.13-bone50 right now? Or maybe not enough diskspace or something? Feb 17 23:27:12 rcn-ee: I got nothing back from cat /etc/apt/sources.list | grep rcn-ee; does that mean that I have to add you to my sources or something?

Feb 17 23:46:22 Auke, then your image is too old... grab a newer snapshot of either wheezy/jessie: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#2015-02-15 Feb 17 23:46:42 at somepoint this month, a new wheezy image will replace the old anicent may 2014 release Feb 17 23:53:33 Well I do have the one from 2014/05/14. Do I need to get the test snapshot? Feb 18 00:01:32 Auke, well, i implemented the repo/etc mid summer late fall of 2014.. sorry haven't mastered time travel to update the may 2014 image.... Feb 18 00:04:33 Ah that's okay, doubt you'd have the time to master time travel Feb 18 00:33:09 rcn-ee: when I try to flash the emmc with the lxde Flasher (https://rcn-ee.net/rootfs/bb.org/testing/2015-02-01/lxde/BBB-eMMC-flasher-debian-7.8-lxde-armhf-2015-02-01-2gb.img.xz) my leds make the same pattern as kitt Feb 18 00:33:58 any of you guys know if I can wire the NES controller ports to IO on the beaglebone? Feb 18 00:34:07 I can only find info for the Pi Feb 18 00:34:09 Yes. Feb 18 00:34:30 what am I doing wrong? Feb 18 00:42:52 agmlego: have a link? Feb 18 00:43:20 https://www.google.com Feb 18 00:43:56 Milenko: But sriously, the principles are all the same; just use similar IO on the Bone to what the Pi uses, then write your code to suit. Feb 18 00:44:14 Ok Feb 18 00:45:00 rcn-ee: Interesting the dra series, although quite disturbing they are targeted for cars Feb 18 00:46:09 GenTooMan: Why disturbing? Feb 18 00:48:36 : Thier is already enough problems with distracted driving. Feb 18 00:48:54 Are there? Feb 18 00:49:22 * agmlego seems to be doing OK. Feb 18 00:49:25 ;-P Feb 18 00:50:51 agmlego : if only everyone else was as competent .. :p Feb 18 00:51:06 agmlego: In 2014 the number of acidents due to people not paying attention while driving went up 1%. That doesn't seem like a lot but since "car infotainment" systems have become prevent it has increased each year 1% over the whole. Over 11 years time a bit of math will discover the number of acidents due to this is now becoming more common than any other issues such as weather related problems. Feb 18 00:51:43 GenTooMan: Assuming people are permitted to continue driving vehicles manually. Feb 18 00:52:37 yea how long it will be before autonomous vehicles Feb 18 00:52:45 -2 years. Feb 18 00:53:00 Right now we will have more ignorant people incapable of doing things. Feb 18 00:53:19 Good. Gets rid of them. Feb 18 00:53:23 Culls the herd. ;-P Feb 18 00:54:05 It reminds me of NYS dumbing down the driver test because "not enough were passing" instead of "maybe they are idiots and shouldn't be driving?" Feb 18 00:54:36 Firm believer in darwinism I see LOL Feb 18 00:55:05 Well, yeah. Seems to work fine. Feb 18 00:57:20 Anyhow I was looking at the PRU on the BBB. It appears to be designed for sequentially framed bit protocols but it's a bit scattered on doing that. Feb 18 00:57:39 Well the information that is :D Feb 18 00:57:53 It is designed for any realtime tasks. Feb 18 00:58:23 That includes low-jitter data transfer. ;-P Feb 18 00:59:38 I was looking for something that would allow 6:4 or 5:4 encoding type things. Having DC NUL balance is important in sequential bit data that is galvanically isolated or optically isolated. Feb 18 01:30:03 hello. I was wondering how I can get a kernel with g_dbgp module on this Element 14 BBB Feb 18 01:30:21 fchmmr: ooh, you're everywhere Feb 18 01:30:40 mrnuke : download the sources, and build ? Feb 18 01:30:58 mrnuke, yep Feb 18 01:31:40 veremit: heh, I was hoping I could avoid that. Feb 18 01:32:17 mrnuke .. think you might be unlucky there :p Feb 18 01:32:56 mrnuke, linux 3.8.13-bone69 Feb 18 01:33:10 veremit: can I use mainline, or do I have to get _this_ specific branch of _this_ specific's person's tree? Feb 18 01:33:13 rcn-ee put the module in that, it's probably in newer builds too Feb 18 01:33:36 mrnuke, mainline might work Feb 18 01:34:12 I recommend .. https://eewiki.net/display/linuxonarm/BeagleBone+Black Feb 18 01:34:46 but yea .. rcn-ee might be able to guide you further .. Feb 18 01:40:21 well, I found this https://rcn-ee.net/deb/wheezy-armhf/v3.8.13-bone69/ . Let's give it a try Feb 18 01:40:40 (even though it will probably take me longer than just building the darn thing) Feb 18 01:53:34 mrnuke, so install that kernel? Feb 18 01:54:59 GenTooMan, cars was the only option, remember they nuked their cell division... Feb 18 01:56:36 rcn-ee: Yes because they sold off their base transmitter section ... and since everyone else combined the two they had no choice :D Feb 18 01:57:02 rcn-ee: hold on, I'm a slow learner. I just realized there's an install script that tells me exactly how to upgrade Feb 18 01:57:47 mrnuke, on newer imags you can just: sudo apt-get install linux-image-3.8.13-bone69 Feb 18 01:58:36 well, duh! THANKS! Feb 18 01:58:45 that seems to work on my BBB Feb 18 01:58:55 (I just bought it yesterday) Feb 18 01:59:06 that's the method going forward.. ;) Feb 18 01:59:38 that was way too fast Feb 18 01:59:51 that command should be fined for speeding Feb 18 01:59:57 in a scool zone !!! :p Feb 18 02:03:31 let me guess, I need to edit uboot files to get it to boot the new kernel Feb 18 02:03:59 no, on anything newer then sep 2014 images, just reboot... Feb 18 02:04:08 (cat /etc/dogtab) Feb 18 02:04:11 (cat /etc/dogtag?
