**** BEGIN LOGGING AT Tue Oct 03 03:00:01 2017 Oct 03 04:30:50 The wireless led of BBBW is not blink after flash emmc with debian 9.1. Can somebody help me to figure out this issue? Thanks Oct 03 04:31:17 Have you ever been able to update your board? Oct 03 04:32:13 Yes I updated it. Oct 03 04:32:39 What is the issue if the board updates, no offense? Oct 03 04:33:09 I update it with sudo apt-get update. Oct 03 04:33:26 Me too. I update my BBBW with sudo apt update. Oct 03 04:33:51 I don't know why this issue appeared after reflashing emmc Oct 03 04:33:55 So, the LED signifying that you are wirelessly attached does not blink? Oct 03 04:33:56 Oh. Oct 03 04:34:10 What is your cat /etc/dogtag? Oct 03 04:34:53 It is 'BeagleBoard.org Debian Image 2017-08-31' Oct 03 04:35:05 Oh and are you with a SD Card or flasher Oct 03 04:35:06 ? Oct 03 04:35:16 flasher. Oct 03 04:35:32 Oh. That is very odd. Please hold. Oct 03 04:35:37 I transfered the image from sd card to emmc Oct 03 04:36:07 Oh. Do your three LEDs light up in a row? Oct 03 04:36:24 Not the LEDs that show heartbeat. Oct 03 04:36:38 ... Oct 03 04:36:55 These would be the three that just shine and do not go off until the board is powered down. Oct 03 04:37:03 Only first four leds blink in heartbeat Oct 03 04:37:18 And you have wireless connectivity? Oct 03 04:38:09 Yes I do! But beaglebone is not connected with wireless Oct 03 04:38:34 Wait! The BBBW does not have wireless conectivity? Oct 03 04:38:58 Yes Oct 03 04:39:02 connmanctl cmd in the terminal... Oct 03 04:39:28 and then... Oct 03 04:40:07 Error wifi: Method "SetProperty" with signature "sv" on interface "net.connman.Technology" doesn't exist Oct 03 04:40:15 This error appear Oct 03 04:40:32 when I use 'enable wifi' Oct 03 04:40:39 Dang. type services Oct 03 04:41:37 No service will appear. b/c wifi is not enable in BBBW Oct 03 04:41:52 Then, agent on Oct 03 04:41:59 Oh. Oct 03 04:42:07 Was it always this way? Oct 03 04:42:42 yes I tried a lot to figure out but this appear same.. Oct 03 04:43:21 Hmm...I know! Try to use a new image with new software. I just tried mine today and it worked with the 9.1.x Sept. version. Oct 03 04:43:47 The connman stuff, from what I am told, has bugs. Oct 03 04:43:59 can you please send me the link of this version. Oct 03 04:44:06 I am not 100% positive but I have heard this... Oct 03 04:44:07 Sure. Oct 03 04:44:10 Please hold. Oct 03 04:45:51 https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#2017-10-01_-_Debian_9_.28Stretch.29_-_Weekly is what I found to work for me. Oct 03 04:46:13 I would get the SD Card image first. Oct 03 04:46:39 Ok thanks Oct 03 04:47:00 Did you transfered the image in emmc Oct 03 04:47:02 ? Oct 03 04:47:12 No. I can use the flasher image instead. Oct 03 04:47:22 Use the flasher if it is necessary. Oct 03 04:48:21 I don't understand the word 'flasher'. is it mean to keep image in sd card Oct 03 04:48:23 ? Oct 03 04:48:52 Flasher uses your eMMC instead of the SD Card for the image file. Oct 03 04:49:25 OK! how can I use flasher Oct 03 04:49:29 ? Oct 03 04:49:53 For instance: If you use the flasher image they have listed, just take out the SD Card once you are done flashing the image. Oct 03 04:50:14 The board will power down by itself and then you take the SD Card out and plug your machine in. Oct 03 04:50:35 Okay Now I get it. Thank you Oct 03 04:50:39 Yep. Oct 03 04:51:12 I also do it previously same step. but same issue appeared. Oct 03 04:51:23 Heh? Oct 03 04:51:28 Oh. Oct 03 04:51:30 I got you. Oct 03 04:51:43 Um, are you using Linux or Win? Oct 03 04:51:52 Win Oct 03 04:52:04 Use etcher and 7-zip. Oct 03 04:52:17 Etcher will burn your image file. Oct 03 04:52:18 Yes I use 7-zip Oct 03 04:52:35 7-zip is the utility to compress your image file/extract it. Oct 03 04:52:50 oh. I used previously the win32diskimager Oct 03 04:53:10 Now I'll try with etcher Oct 03 04:53:12 Do not use that anymore. Bugs or something odd. Who knows? Etcher works fine. Oct 03 04:53:14 Okay. Oct 03 04:53:33 Okay! Oct 03 04:53:39 Let me know what happens...cool! Oct 03 04:54:00 Okay I'll thanks Oct 03 04:54:14 Yep... Oct 03 04:56:33 download .img file > open it with 7-zip > extract it/compress it in 7-zip > Plug the sd card in to the BBBW > Let the machine power down > take the sd card out > power on your BBBW machine! Oct 03 04:56:56 ... Oct 03 04:57:19 Sorry...after extracting it/compressing it, you need to use etcher to burn the image to the SD Card. Oct 03 04:57:25 Sorry about that. Oct 03 04:57:33 Okay! Now I am downloading the imge./ Oct 03 04:57:38 Np Oct 03 04:58:01 maheen_: Do you have 7-zip? Oct 03 04:59:02 Yes... Oct 03 04:59:13 Cool! Oct 03 04:59:53 Hey maheen_: Are you almost done downloading your .img file? I am getting tired. Oct 03 05:00:39 No. It's only 570/742 MB Oct 03 05:00:53 Okay. Oct 03 05:01:17 Are you downloading that file on your Win desktop/laptop? Oct 03 05:01:30 win desktop Oct 03 05:01:35 Okay. Good. Oct 03 05:01:41 I just wanted to make sure. Oct 03 05:01:53 Do you use Linux? Oct 03 05:01:57 Ohkay Oct 03 05:01:59 Outside of the BBB? Oct 03 05:02:08 Okay? Oct 03 05:02:10 Yes I have ubuntu machine Oct 03 05:02:18 Okay...that is good knowledge. Oct 03 05:02:24 So, what next? Oct 03 05:02:35 You should open that file with 7-zip! Oct 03 05:02:54 it's just 650/742 MB Oct 03 05:02:56 Oh. Oct 03 05:03:32 I am also downloading etcher Oct 03 05:03:42 Oh...okay. Oct 03 05:03:44 Good. Oct 03 05:04:59 The image is downloaded. Oct 03 05:05:12 and also etcher Oct 03 05:05:25 Now start flashing it Oct 03 05:05:29 No! Oct 03 05:05:44 Open the .img file with 7-zip. Oct 03 05:06:13 Extract it with 7-zip and wait until it is done. Let me know when it is done, please. Oct 03 05:07:00 Yes I am extracting it with 7-zip Oct 03 05:07:32 Good...it should not take that long. Afterwards, please remember what directory you saved the file in. Oct 03 05:07:47 It's done Oct 03 05:07:51 Yes I do Oct 03 05:08:03 Okay. Um, now open etcher. Oct 03 05:08:13 Do you have your SD Card handy? Oct 03 05:08:28 yes Oct 03 05:08:45 Plug that bad boy into your Win machine, not the BBBW. Oct 03 05:09:12 yes Oct 03 05:09:32 Yes? Did you plug it in to the Win machine? Oct 03 05:09:47 It is a Micro SD Card with an adapter, right? Oct 03 05:09:48 can I format it with sd card formatter? Oct 03 05:10:00 Yes, just format it. Oct 03 05:10:06 You can. Oct 03 05:10:41 Is it done yet? Oct 03 05:11:02 Yes I formatted it Oct 03 05:11:25 Cool beans...okay! Now, use Etcher to burn the image to the SD Card. Oct 03 05:12:31 Yes I am doing Oct 03 05:12:50 cool, cool. I bet that thing does not take long at all. Oct 03 05:12:59 You seem to have very fast Internet. Oct 03 05:13:23 Or that computer is fast too. Oct 03 05:13:28 Who knows? Oct 03 05:13:42 haha.. No the internet speed is okay not fast Oct 03 05:13:47 Oh. Oct 03 05:14:14 I tried to download something the other day. It took an hour. That was wasted time, i.e. so far. Oct 03 05:14:29 Oh Oct 03 05:14:34 Yep. Oct 03 05:14:43 it means you slow connectivity Oct 03 05:14:48 Probably. Oct 03 05:14:51 *have Oct 03 05:14:54 Yep. Oct 03 05:14:55 okay Oct 03 05:14:59 Okay? Oct 03 05:15:08 Is it done? Oct 03 05:15:28 No! It's only 38% Oct 03 05:15:34 Oh. Oct 03 05:15:40 Okay. I will wait. Oct 03 05:16:02 ok. I'll update when it done Oct 03 05:16:16 Do you think you have it from here? Oct 03 05:16:28 Or, do you need more advice on setup? Oct 03 05:17:53 Well! I want to ask just one thing that can I change something in uEnv.txt file before booting the BBBW? Oct 03 05:18:05 Okay. Oct 03 05:18:08 Shoot! Oct 03 05:18:23 shoot? Oct 03 05:18:31 I mean, go ahead. Oct 03 05:19:11 what change should I do? I Oct 03 05:19:20 Nothing. Oct 03 05:19:29 I would not change any files before boot. Oct 03 05:19:50 Change them after you know your machine is in working order. Oct 03 05:19:51 BBBW automatically flash ?? Oct 03 05:20:07 Is the .img file done yet? Oct 03 05:20:17 And yes. Oct 03 05:20:50 10% validating Oct 03 05:21:04 what does it mean?? Oct 03 05:21:20 The BBBW flashes automatically. All you need to do is put the SD Card in and it does the work. Linux! Oct 03 05:21:54 Oh, validating. Making sure it has the correct "chksum" or something like that...I forget to tell you the truth. Oct 03 05:22:07 ... Oct 03 05:22:36 chksum? Oct 03 05:22:46 what truth? Oct 03 05:22:54 Sorry. I was joking. Oct 03 05:23:05 Np.... Oct 03 05:23:19 I will look up the validation info. Oct 03 05:24:39 https://github.com/resin-io/etcher has more info. on the ideas revolving around etcher. Oct 03 05:25:06 ... Oct 03 05:25:20 Is the validation process over yet? Oct 03 05:25:26 done with burning image Oct 03 05:25:57 Cool, now plug that SD Card in and wait until the BBBW powers down on its own. Oct 03 05:26:21 Put the SD Card in and add power. USB if you have it. Oct 03 05:27:59 maheen_: I forget, which style did you end up downloading? Did you get the flasher or sd card image file? Oct 03 05:28:34 I get rar file Oct 03 05:28:49 What is rar? Oct 03 05:28:51 compressed Oct 03 05:28:54 *compressed file Oct 03 05:29:12 No, which .img file did you download to your Win computer? Oct 03 05:29:22 Flasher or standalone? Oct 03 05:29:42 I didn't check it? Oct 03 05:30:00 Now BBBW is in flashing mode Oct 03 05:30:10 Are the lights going back and forth? Oct 03 05:30:17 Yes Oct 03 05:30:39 Okay...phew! You have the flasher image. Oct 03 05:31:04 Once it is done and powers itself down, take out the sd card and apply power. Oct 03 05:31:04 how can I verify it ? Oct 03 05:31:16 Ok Oct 03 05:31:22 What does your .img file say on it? Oct 03 05:31:40 Flasher? 4GB? IoT? Oct 03 05:32:31 Ixqt Oct 03 05:32:39 and in last 4gb Oct 03 05:32:55 BBB-blank-debian-9.1-lxqt-armhf-2017-10-01-4gb Oct 03 05:33:27 this is the name of image file Oct 03 05:33:27 Okay. Well, you know because of how the LEDs are going back and forth. Oct 03 05:33:39 Instead of heartbeat. Oct 03 05:34:52 Another way to tell is this: The machine will power itself down without having your pop-up file screen of the BBBW location on your hard drive. Oct 03 05:34:56 how much time it take to power down all led? Oct 03 05:35:22 The machine will power down itself in about 40 minutes or under. Oct 03 05:35:31 ok Oct 03 05:36:06 If your machine is new, it will take less time. If you have a 10 SD Card, rather than 4, it should not take that long. Oct 03 05:36:35 what is 10 and 4 mean? Oct 03 05:36:45 Category of SD Card. Oct 03 05:36:55 oh Oct 03 05:36:58 What does it mean, no clue. Oct 03 05:37:05 It is just some category to me. Oct 03 05:37:24 done with flashing Oct 03 05:37:34 Did the machine power down itself? Oct 03 05:37:34 all leds powered down Oct 03 05:37:38 Cool! Oct 03 05:37:39 Yes Oct 03 05:37:45 Unplug it. Oct 03 05:38:06 Then, take out the SD Card. Oct 03 05:38:15 Yes I did Oct 03 05:38:38 Okay, then plug your machine in. Oct 03 05:39:03 Oh no! still the WL led is not blink Oct 03 05:39:10 Please hold on. Oct 03 05:39:18 It takes a some time. Oct 03 05:39:38 ok I am waiting Oct 03 05:39:56 I am beat man. I need sleep. Oct 03 05:40:10 Is the machine showing up on your Win machine? Oct 03 05:40:21 Yes Oct 03 05:40:31 Are those LEDs lit? Oct 03 05:40:55 Yes! four leds are in heartbeat position Oct 03 05:41:01 Great. Oct 03 05:41:08 but WL and BT led not blink Oct 03 05:41:11 Wait for it. Oct 03 05:41:20 They do not blink. Are they lit at all? Oct 03 05:41:58 No they are not Oct 03 05:42:20 Damn. Okay. Do you use PuTTY or a Linux Distro to ssh in? Oct 03 05:42:28 putty Oct 03 05:42:42 PuTTY that bone up! Oct 03 05:42:58 bone? Oct 03 05:43:04 BBBW! Oct 03 05:44:07 Okay. Use PuTTY and type in 192.168.7.2 and wait for it! Oct 03 05:44:20 I login BBBW with debian via putty Oct 03 05:44:33 Your ssh screen in PuTTY should show up. Oct 03 05:44:34 Oh. Oct 03 05:44:35 Okay. Oct 03 05:44:42 connmanctl Oct 03 05:44:59 yes I do Oct 03 05:45:06 maheen_: I am getting very tired. I will most likely need sleep soon. Oct 03 05:45:28 What time is it now? Oct 03 05:45:43 in BBBW? Oct 03 05:45:45 maheen_: What time do you have? Oct 03 05:45:53 No, in real time...now. Oct 03 05:45:59 10:47 AM Oct 03 05:46:14 and you? Oct 03 05:46:27 Damn. No wonder. I am beat man and it is almost 1:00 a.m. Oct 03 05:46:49 still wl led not lit Oct 03 05:46:52 Did your bone get onto PuTTY wtih no issues? Oct 03 05:47:17 yes it connected it with putty without any issue Oct 03 05:48:18 type connmanctl Oct 03 05:48:31 If that does not work, look at this: https://pastebin.com/pdFa1tar. Oct 03 05:48:35 I typed. what next Oct 03 05:48:47 ? Oct 03 05:49:04 okay...now! type services. Oct 03 05:49:10 services Oct 03 05:49:15 then... Oct 03 05:49:16 agent on Oct 03 05:49:27 agent on Oct 03 05:49:37 but just once for those cmd's. Oct 03 05:49:44 there is nothing appeared in services Oct 03 05:49:51 good. Oct 03 05:49:54 Type...

Oct 03 05:51:31 how can it show? Oct 03 05:51:41 still WL led is not lit Oct 03 05:52:23 Um, leds are not lit. Got it. So, the router login name is not showing? Oct 03 05:52:46 yes Oct 03 05:52:50 of cource Oct 03 05:53:14 Highlight that long name to the right of that router login name, please. Oct 03 05:53:53 now, right click your mouse. Oct 03 05:54:14 there is nothing appeared Oct 03 05:54:25 which thing I light up? Oct 03 05:54:36 *highlight Oct 03 05:55:14 Um...highlight that long-name to the right of your router login name. Oct 03 05:55:44 Linux beaglebone 4.9.52-ti-r64 #1 SMP PREEMPT Sat Sep 30 00:11:40 UTC 2017 armv7l Oct 03 05:55:53 No...what? Oct 03 05:56:14 What are you looking at once you type agent on? Oct 03 05:56:29 Pastebin.com it! Look at that pastebin.com above, please. Oct 03 05:56:55 yes I looked it. Oct 03 05:57:16 I am about to jump out the window and off this bridge. Oct 03 05:57:23 Just kidding! Oct 03 05:57:38 ? Oct 03 05:57:39 I am going to bed. Oct 03 05:57:49 Sorry mate. I will be back tomorrow. Oct 03 05:58:03 I am beat by you and your system requirements. Oct 03 05:58:12 Please forgive me. Oct 03 06:46:17 hi, is there a way to hook a JTAG emulator on a BeagleBone Blue? Oct 03 06:49:55 hello everyone! Oct 03 06:50:34 The WL led is not lit in my BBBW. can please help me to figure out this issue?? Oct 03 06:51:29 carbon-cabron: https://github.com/beagleboard/beaglebone-blue/blob/master/docs/BeagleBone_Blue_ShortSpec.pdf Oct 03 06:57:11 jkridner: http://beagleboard.org/blue claims that https://github.com/beagleboard/beaglebone-blue has a SRM, but I don't see it Oct 03 06:57:31 tbr, i noticed the TDO, TDI, TCK and so on pins on the bottom side. My question is, do i have to solder up the wires or is there some kind of connector i can buy Oct 03 06:58:04 or some sort of plastic housing which allows some sort of a connector Oct 03 06:58:47 carbon-cabron: ok that wasn't clear. on the BBB there is a standard connector footprint. As I can't locate the SRM, I don't know how that works for the BB-blue Oct 03 06:59:43 i'd love to ry some debugging as shown here http://processors.wiki.ti.com/index.php/PRU-ICSS_Debug_on_AM335x Oct 03 07:00:10 ok I found the board layout PDF at least Oct 03 07:00:24 it looks like it's just a group of test-pads Oct 03 07:00:36 exactly Oct 03 07:00:46 sorry, what is SRM again Oct 03 07:00:52 I have beagle black wireless. issue is in that it's WL led is not lit Oct 03 07:00:53 ? Oct 03 07:00:56 you'd either need to fashion a "bed of nails" out of pogo pins or solder carefully to them and tack the wires down with hot glue Oct 03 07:01:04 System Reference Manual Oct 03 07:01:22 can anyone figure out this issue?? Oct 03 07:01:48 maheen: well, is it powered? what OS are you running on it? Oct 03 07:02:18 powering a LED is as simple as "apply voltage across", but I suspect that's not the answer you're looking for Oct 03 07:02:45 Yes it is powered. I used debian 9.1 Oct 03 07:03:09 No! it is built in led Oct 03 07:03:26 it should automatically on Oct 03 07:03:48 carbon-cabron: https://github.com/beagleboard/beaglebone-black/wiki/System-Reference-Manual is the one for the black Oct 03 07:04:09 https://github.com/beagleboard/beaglebone-black/wiki/System-Reference-Manual#512_CTI_JTAG_Header is much more friendly Oct 03 07:04:36 but the footprint is completely different Oct 03 07:07:07 maheen: I do not own a BBBwireless so can't help you with that. I only have a beaglebone-white and a beaglebone-black. Of course jkridner could send me some boards for the future to allow me to help with such things. ;-) Oct 03 07:12:36 you are right. many things are so much friendly for BB Black. Oct 03 07:13:07 if i could only get my hands on those bed of nails u mentioned earlier Oct 03 07:15:55 Maybe the Octavo Systems OSD335x System-in-Package already provides some sort of emulator.. is it even possible? Oct 03 07:17:52 I wouldn't expect it to. Even the simplest FTDI usb chip (as used on the bbb-white) was a significant part of the BoM Oct 03 07:18:47 cuz the difference between Blue and Black is that the Blue has the octavo system meanwhile the Black has the TI AM3358 Oct 03 07:20:29 ok, so thats not the option Oct 03 07:21:22 the TI's CCS debugging is completely useless in BB Blues case, am i correct? Oct 03 07:21:54 how can you debug PRUs then? Oct 03 07:24:15 never done anything with those Oct 03 07:24:29 though I think most people don't use JTAG to work with those Oct 03 07:26:32 no one i talked to hasn't done anythong with PRUs Oct 03 07:26:36 :) Oct 03 07:27:40 well i really want to do some stuff in hard real time and non determinism is really unacceptable Oct 03 07:28:21 tbr, do u have a BB Black as well? Oct 03 07:29:18 yes Oct 03 07:29:31 BeagleBoard-X15 is there a camera option? Oct 03 07:29:50 where can I find more info about it? Oct 03 07:31:48 https://github.com/beagleboard/beagleboard-x15/blob/B1/BeagleBoard-X15_SRM.pdf?raw=true says there is one camera port on one of the expansion connectors Oct 03 07:32:10 for details you might need to refer to the TRM of the AM5728 Oct 03 07:33:18 There is no camera option on the AM5728 only on the AM571x and AM50x so i'm wondering how it is done Oct 03 07:35:32 you could ask on the x15 google group Oct 03 07:35:51 ok Oct 03 07:36:23 http://files.linuxgizmos.com/ti_am57x_evm_details.jpg - this shows a camera module. so if you look at the TI EVM documentation Oct 03 07:36:26 ... Oct 03 08:49:20 carbon-cabron: I'm pretty sure there are PRU debuggers. The PRU core's debug controls are all via memory-mapped registers, so there's no real advantage to debugging it via jtag Oct 03 08:50:03 i.e. jtag is in that case just used to access the pru registers (which you can also access from linux userspace via uio or /dev/mem ) Oct 03 08:52:40 ok, but sure it is nicer to see the contents of those register in a tool like CCS Oct 03 08:52:49 via jtag Oct 03 08:54:11 as you said zmatt, there should be some sort of application or binary to get the contents of the registers Oct 03 08:54:26 well, if the bb blue has an unsoldered jtag header on the bottom side (like the bb black does) you can solder it on if you really want jtag Oct 03 08:54:32 yes, there are pru debuggers Oct 03 08:55:40 in fact iirc there's more than one, but this is the first one I just found using google -> https://github.com/poopgiggle/prudebug Oct 03 08:57:23 sorry, https://sourceforge.net/projects/prudebug/ seems to be the primary site for that Oct 03 08:57:45 I think Oct 03 09:01:25 ooh, looks pretty nice Oct 03 09:01:31 thanks zmatt Oct 03 09:02:15 BB Blue indeed has an unsoldered jtag header but it is nothing like the Black's Oct 03 09:02:25 it only has 7 pins Oct 03 09:02:34 oh that sucks Oct 03 09:02:43 that means custom cable Oct 03 09:05:45 looks more like 7 test points... not even having ground or vref available Oct 03 09:06:12 (which you'd therefore need to obtain from elsewhere on the board) Oct 03 09:06:18 yuck Oct 03 09:14:06 What is the current recommended branch/tag to use on https://github.com/beagleboard/linux.git? Oct 03 09:14:50 https://imgur.com/jQX80Sy Oct 03 09:14:56 this is the back side Oct 03 09:16:54 Humpelstilzchen: depends Oct 03 09:17:05 ok but getting the Vref and GND wouldnt be much of a problem Oct 03 09:18:26 zmatt: BB Black, just want to play Oct 03 09:18:41 Havn't updated it in a while Oct 03 09:19:00 carbon-cabron: sure, although that means using jumper wires or such instead of a simple connector. also, ideally you'd want ground close to the signal lines for signal integrity reasons (although with jtag I've often managed to get away with really horrid-looking setups without any problems) Oct 03 09:19:40 Humpelstilzchen: if you just want a new kernel, apt-get install it. if you want to compile your own kernel (e.g. to customize it), I'd actually suggest one of the build-repositories Oct 03 09:20:33 Humpelstilzchen: https://github.com/RobertCNelson/ti-linux-kernel-dev is the build repo for the currently-default 4.9-ti kernel series Oct 03 09:21:56 zmatt: ok thanks Oct 03 09:24:22 carbon-cabron: one advantage of having a debugger locally on the system instead of via jtag is that it should also be a lot faster Oct 03 09:25:13 sure u right. and theres another thing i was concerned.. the breakpoints Oct 03 09:25:44 afaik only software breakpoints are supported Oct 03 09:26:07 but the prudebugger sw has them Oct 03 09:26:17 i.e. an instruction is replaced by HALT before execution and the debugger will remember what the original instruction was and replace it Oct 03 09:26:37 have u ever used this tool? Oct 03 09:26:41 prudebug Oct 03 09:27:03 no, but that's how software breakpoints are done in general. and I know pru has no support for hw breakpoints Oct 03 09:30:44 hw breakpoints? Oct 03 09:30:58 hardware breakpoints? Oct 03 09:31:10 yeah. hw breakpoints mean you can configure a breakpoint location/condition in special debug registers Oct 03 09:31:40 ok so the jtag emulator takes care of that i suppose Oct 03 09:31:44 ? Oct 03 09:32:20 pru has no hw breakpoint functionality Oct 03 09:32:53 jtag debuggers in general support use both hw breakpoints (when available) and sw breakpoints, since the number of hw breakpoints is often quite limited Oct 03 09:33:36 hw breakpoints are particularly useful on microcontrollers since you can set them in code that cannot be (easily) modified, e.g. flash memory or ROM Oct 03 09:33:54 ok got it, i am not rely familiar with how does the JTAG emulator work in details Oct 03 09:34:03 and also how the breakpoints are set Oct 03 09:34:34 realy* Oct 03 09:46:57 these are my notes (in the form of a header) on the pru core interface: https://liktaanjeneus.nl/pdsp.h.html ... it's pretty basic Oct 03 09:48:44 like I said, doing breakpoints on a pru core is entirely up to the debugger: to set a breakpoint it replaces the instruction at that location by a HALT (while remembering the original instruction). to remove the breakpoint it restores the original instruction Oct 03 09:49:49 to single-step over a breakpointed instruction, it temporarily removes the breakpoint during that single step Oct 03 09:50:16 to resume from a breakpoint, it single-steps over it and then resumes execution Oct 03 09:50:46 it's not elegant, but it works :) Oct 03 10:28:57 hello Oct 03 10:30:48 I would like to know if there is such difference between the beagle black 1C and this one on Oct 03 10:32:04 http://it.farnell.com/beagleboard/bbone-black-4g/beaglebone-black-rev-c-cortex/dp/2422228 Oct 03 10:32:11 carbon-cabron: please don't unnecessarily use private messages. and no, not really Oct 03 10:32:34 or tell me where i can buy the black 1C Oct 03 10:32:58 pavlx: 1C ? that's not a revision number used by the BBB Oct 03 10:33:32 and what it means? Oct 03 10:33:58 all currently-produced beaglebone black (including the one you linked to at farnell) are revision C Oct 03 10:34:12 ah, ok Oct 03 10:34:58 beagle should be C? Oct 03 10:35:04 you can find the revision history here: https://www.elinux.org/Beagleboard:BeagleBoneBlack#Board_Revisions_and_Changes Oct 03 10:36:25 ok, thank you, so I order it Oct 03 10:37:28 I'll go to use with my laptop t400 ibm Oct 03 10:37:45 t400 was already lenovo.. Oct 03 10:37:47 to replace EFI Oct 03 10:38:28 ?? Oct 03 10:40:53 beacause i agree to the movment of Free Software https://www.gnu.org/ https://www.fsf.org https://fsfe.org http://ffii.org http://eff.org Oct 03 10:41:09 what does a beaglebone have to do with your laptop? Oct 03 10:41:25 and i DON'T want BLOBS in my harware Oct 03 10:41:38 reflash Oct 03 10:41:42 all hardware has blobs, and the hardware itself is also proprietary Oct 03 10:42:30 pavlx: Did you heard of coreboot? Oct 03 10:42:35 (well, iirc there are completely open processors, but not something that can really compete with modern x86 or arm processors) Oct 03 10:42:53 https://libreboot.org/docs/install/t400_external.html Oct 03 10:43:08 yes Oct 03 10:43:16 a good job Oct 03 10:44:03 also, the AM3358 SoC used on the beaglebones have a closed-source bootloader in ROM (not replacable). same goes for every other ARM-based SoC that I'm familiar with Oct 03 10:44:42 all is replicable Oct 03 10:45:08 that's a different word from replacable Oct 03 10:45:32 the ROM is this case is actual ROM, not flash Oct 03 10:45:34 in the movment of free software we speak of: free software and non software Oct 03 10:46:32 *non-free Oct 03 10:46:36 what's your point? Oct 03 10:46:58 my point is to use Free Software Oct 03 10:47:52 why Texas Instruments uses non free software in ROM? Are they idiots? Oct 03 10:48:33 why would they have any motivation whatsoever to make that part open source? Oct 03 10:49:06 especially since the ability to modify it would have very limited benefit, since the code is still in ROM and cannot be changed without producing a new die mask Oct 03 10:49:27 pavlx: so you can't brick your µC Oct 03 10:49:46 if they don't do, i'll do myself Oct 03 10:50:04 pavlx: lol Oct 03 10:50:19 yes, go design and produce your own SoC, let me know how that works out Oct 03 10:50:25 * tbr hands pavlx a bucket of sand labelled "my first IC starter kit" Oct 03 10:52:22 pavlx: I wouldn't even be surprised if they *can't* release the source code to the ROM bootloader due to contractual obligations with third parties Oct 03 10:52:49 i invite to read http://ur1.ca/h1p3g/ Oct 03 10:53:17 dead link Oct 03 10:53:23 also permanent ROM is fine even with the free software zealots Oct 03 10:54:22 which contractual obligations? Oct 03 10:54:48 pavlx: note the "I wouldn't be surprised", i.e. I don't know whether this is true Oct 03 10:55:16 but when I looked at the ROM code disassembly it seemed rather... heterogeneous. like different parts were produced using different compilers and then linked together Oct 03 10:56:53 look here: https://archive.org/download/Trusted-Computing/Trusted-Computing_LAFKON_HIGH.ogv Oct 03 10:57:02 why? Oct 03 10:57:52 what is your position: Free Software or NON free software? Oct 03 10:58:34 what is your goal here: to get technical assistance on a beaglebone-related subject or to rant about your personal beliefs? Oct 03 10:58:52 pavlx: How does free software help you on a ROM? You have no way to verify it Oct 03 10:59:44 i'll decompile it Oct 03 11:00:21 pavlx: You have to read it first. How do you want to verify that the code you read is the one that gets executed? Oct 03 11:00:49 don't worry Oct 03 11:01:13 the first 128 KB of the ROM on the am335x cannot be read in the first palce Oct 03 11:01:14 *place Oct 03 11:01:41 we will do it Oct 03 11:02:02 cool, let me know when you've extracted it. I would be genuinely interested Oct 03 11:02:36 (I have extracted this area from the ROM of the related dm814x, but I was able to do that because TI fucked up the protection there) Oct 03 11:03:54 the video you linked is complete bullshit btw and doesn't provide any support for the claims it makes Oct 03 11:09:03 https://github.com/qoriq-open-source/linux-v4.1.8-sdk/blob/master/arch/arm/boot/dts/am335x-nano.dts Oct 03 11:11:37 do you have a question about that file or are you just randomly pasting links? Oct 03 11:15:42 oh well, I have other things to do anyway Oct 03 11:15:43 afk Oct 03 13:15:27 zmatt: the page looks updated, should I try it? https://elinux.org/Beagleboard:Expanding_File_System_Partition_On_A_microSD Oct 03 13:15:39 yeah I updated it Oct 03 13:17:14 thanks zmatt! Oct 03 13:20:40 zmatt: is the size here for a 16GB sd card? 15523839 Oct 03 13:21:46 zmatt: i see now Oct 03 13:29:11 zmatt: i went through the process but i still see 3.3G for /dev/mmcblk0p1 3.3G 2.9G 135M 96% / Oct 03 13:30:07 after a reboot Oct 03 13:30:46 you also did the resize2fs step ? Oct 03 13:31:01 zmatt: missed that Oct 03 13:31:06 good call Oct 03 13:31:16 (no reboot needed after that) Oct 03 13:32:14 zmatt: thanks again! Oct 03 16:15:33 I might have a stupid question, still looking for the answer - is there a BB board that has *both* wired ethernet and built-in wireless interfaces? Oct 03 16:16:03 so far, i think i've only found boards where the wired iface has been replaced with a wireless one … Oct 03 16:16:49 but i just tripped over references to the SanCloud BB Enhanced and am trying to find more detail on the "wifi/bluetooth option" Oct 03 17:17:56 ralfiboy: yeah the beaglebone enhanced has gigabit ethernet and wifi Oct 03 17:18:23 so i found a pic of it and it looks like the wifi option is really just a minicape on top? Oct 03 17:19:22 they integrated a usb hub and attached a wifi chipset to one of its ports Oct 03 17:20:23 i mostly use a wired iface for my work, but occasionally need a wireless test node and was hoping i could have it integrated into the same device w/o adding a wifi dongle. Oct 03 17:21:06 but i'm not sure i like the BBE … starting to embrace the dongle approach. Oct 03 17:21:06 :) Oct 03 17:21:24 thanks! Oct 03 17:21:30 wireless functionality can also be added using a cape, but I don't know if there's any ready-made Oct 03 17:21:52 i saw some old ones, but they look pretty old and discontinued. Oct 03 17:28:05 one for beaglebone white. :) Oct 03 17:28:51 a BBW cape may or may not be BBB-compatible Oct 03 17:29:26 i think this was, there was a link to a doc on how to make it work … but it also looked like a HUGE cape … so that's not going in my kit. Oct 03 17:29:57 heh Oct 03 17:44:49 I have a problem with a BeagleBone Black when booting from microSD card on Windows. In this case, I cannot connect to it with the IP address 192.168.7.1. I noticed that there is an issue with the Gadget Serial port (because of a yellow exclamation mark on the port in Windows Device Manager). This problem does not occurs if the board boots normally (not on the microSD). Any idea about this? Any help is greatly appreciated. Oct 03 17:52:39 what image is running on card? Oct 03 17:53:20 I very much doubt the difference is due to booting from eMMC vs booting from μSD. most likely it's due to newer or older image Oct 03 17:54:03 bbl Oct 03 18:00:23 The image is ROS Kinetic. Oct 03 18:04:08 WL led is not lit in BBBW. can anybody help on this issue ?? Oct 03 18:10:28 ? Oct 03 18:10:31 ? Oct 03 18:10:33 ? Oct 03 18:10:34 ? Oct 03 18:10:34 ? Oct 03 18:10:35 ? Oct 03 18:10:36 ? Oct 03 18:10:38 ? Oct 03 18:30:58 not on your schedule Oct 03 18:49:19 MAEW: sorry, don't know anything about ROS Oct 03 18:50:43 Doesn't sound like a ROS problem Oct 03 18:52:15 well, it is if they made the image Oct 03 18:53:03 Its probably just an ubuntu with an extra repository added Oct 03 18:53:16 MAEW: where did you get the image from? Oct 03 18:54:04 probably more a windows usb cdc problem Oct 03 18:55:57 well, that too, but apparently it's working for him with a standard debian image (which is what's presumably on eMMC) Oct 03 19:06:04 Not sure if anyone is interested, but I've created a PCB Expansion board for the PocketBeagle to breakout the second USB Port as a Host. Has Power switching and surge suppression. Also has traces for a Si7006 temperature sensor and MMA845xQ series accelerometer. Available from OSHPark. https://oshpark.com/shared_projects/IrizTrr1 Oct 03 19:09:16 zmatt: The above is based on our discussion a few days ago. Oct 03 19:11:26 jkridner: I made a Eagle Library with the Expansion Headers and board outline as a part in Eagle. I don't have anywhere to host it, but wondered if you wanted to put it up somewhere? Oct 03 19:14:45 Hi, i'm having some connection issues with my Beaglebord Green Wireless. Booting from SD using bone-debian-9.1-iot-armhf-2017-09-21-4gb.img.xc. Oct 03 19:16:47 When trying to connect to it from the PC i see the WLAN it created, connected to from the phone due to i dont have wireless on PC. That worked but it doesn't show in PCs File explorer and configuring from phone seems like an unecessary difficult way. Oct 03 19:17:37 BBGW is connected to PC through USB-cable, drivers for Win is installed, but can't access it. Oct 03 19:17:52 Humpelstilzchen: I got the image from this link: http://wiki.ros.org/kinetic/Installation/Ubuntu Oct 03 19:18:47 Jonas: So you can't connect via 192.168.7.2? Oct 03 19:20:10 MAEW: there is no download link on this page on OSRF doesn't provide images so I take it you downloaded a vanilla ubuntu? armhf image? Oct 03 19:20:17 Jonas: You should be able to SSH into it.... Oct 03 19:20:47 Morantz: From phone, yes. From PC, no. Oct 03 19:21:21 Jonas: USB from BB is to phone or PC? Oct 03 19:21:34 USB is to PC Oct 03 19:22:18 Then I think on PC you should be able to connect via SSH to 192.168.7.2 That is bound to the USB Gadget network interface. Oct 03 19:22:27 Morantz: When trying to connect from PC i use Putty, and it gets network time out Oct 03 19:22:49 (At least on a windows PC. Linux or MAC would be 192.168.6.2) Oct 03 19:24:02 I am using the same image (though on a PocketBeagle) and don't have that issue. I have never used a wireless BB, so I guess I can't help you. Sorry.... Oct 03 19:24:55 Morantz: All ok, no problem. I'm all new to this. :) Oct 03 19:25:03 (I am also using Putty...) Oct 03 19:25:21 Sorry, the image was actually downloaded from here: https://rcn-ee.com/rootfs/2017-09-21/microsd/. Oct 03 19:25:22 We all are at some point! Key is to Never Give Up!!!! lol Oct 03 19:25:42 :D Oct 03 19:26:16 Jonas: What Network is wifi? Oct 03 19:26:58 I specifically installed the version: bone-ubuntu-16.04.1-console-armhf-2017-01-23-2gb.img.xz, which doesn't exist in this link anymore. Oct 03 19:27:57 Jonas, and can you connect the PC to the same network? Oct 03 19:28:46 Morantz: I can't connect to the BBGW WLAN, i have no WLAN-connection on it (stationary computer) Oct 03 19:29:03 Morantz: Except from my phone Oct 03 19:29:33 Jonas: hmm... So the BB isn't a client? It is the host? Oct 03 19:30:25 MAEW: ok, might be that this image does not have the usb gadget enabled. I don't know this one. Can you attach your BBB to a HDMI monitor? Oct 03 19:31:51 Morantz: Yes, it creates its own WLAN for configuring purposes as i understand. I had it running earlier, on an older image, but hade some major issues upgrading when trying to upgrade through SSH. My purpose with it is to run Node:RED, and i couldn't update and get it runnig. Hence trying with the latest image. Oct 03 19:31:51 MAEW: also does your windows usb network has an IP set? Oct 03 19:33:10 Jonas: When you plug it into the PC does it open a file system on the PC? Oct 03 19:33:31 Morantz: No, not with the latest image Oct 03 19:34:06 You might have a bad USB cable then. That image DOES open a filesystem for me. Oct 03 19:34:16 Morantz: Currently flashing the SD-card to the old image to see if there is some issues with the card Oct 03 19:34:32 Your cable might not have the data lines in it. Oct 03 19:35:24 Morantz: USB-cable issues... Yeah, that could actually be it... I'll try to find another cable and see if it solves the problem. Oct 03 19:35:50 Morantz: Thanks a lot! :D Oct 03 19:36:03 Jonas: Good luck! I had the problem here. Your welcome! Oct 03 19:36:29 the SAME problem... Oct 03 19:36:51 Humpelstilzchen: I haven't tried connecting my BBB to a HDMI monitor. I will try, but what can this tell? Also, how do I check if my Windows (which is 10) has its USB network IP set. Why is this relevant? Sorry for the inconvenience because I'm not so expert in these things. Oct 03 19:37:25 Morantz: It's easy to think that a USB-cable is a USB-cable and not a charging only cable... Oct 03 19:37:45 MAEW: no windows export here either, try to open a shell (search for cmd) in it type ipconfig Oct 03 19:38:13 JOnas: Exactly! I am ordering some 4 inch USB Cable to have around... Don't want that issue again myself! Oct 03 19:39:23 the bbb is shipped with an usb cable though, is this not the case for the bbgw ? Oct 03 19:40:08 MAEW: I think the driver for the USB port gadget sets that up as it's default. You will only see in the network ports when active. Oct 03 19:41:01 MAEW: Active = Plugged in and booted.. Oct 03 19:41:36 MAEW: (HDMI) it can tell you that the Linux is up and running finished booting. Also it gives you a shell directly to the Linux when usb gadget and getty are not available Oct 03 19:45:07 ..the getty on uart0/J1 Oct 03 19:46:43 Humpelstilzchen: I'm actually sure that the Linux on the microSD is running properly because I can run some tasks (acquire data from a sensor) through the Shell. Now, I'm trying to connect to BBB via IP address through another platform (Matlab). This is where I'm stuck because of the Gadget Serial problem. Oct 03 19:47:45 aah ok Oct 03 19:49:01 MAEW: so did you check if the ip is set on both devices? Oct 03 19:51:29 Humpelstilzchen: I'm looking. This is what Windows IP Configuration says: Oct 03 19:52:11 Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : rice.edu Link-local IPv6 Address . . . . . : fe80::f015:bcb3:5472:36e1%6 IPv4 Address. . . . . . . . . . . : 10.65.64.66 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : fe80::200:5eff:fe00:20c%6 10.65.64.1 Ethernet adapter VirtualBox Host-Only Network: Connection-spe Oct 03 19:53:03 Humpelstilzchen: Sorry for that mess. I cannot find any USB! Oct 03 19:55:44 MAEW: and on BBB/Linux? (Please use a pastebin service instead of pasting in the channel) Oct 03 19:58:35 MAEW: btw why aren't you using the real ethernet nic? Oct 03 20:01:03 Humpelstilzchen: First, this is what the BBB/Linux is giving: https://pastebin.com/nETchZHb. Oct 03 20:02:15 usb0 is loaded, so looks fine on this site Oct 03 20:02:25 uhm usb0 and usb1? Oct 03 20:03:34 And this is the Windows IP Configuration: https://pastebin.com/cxUJWWCw. Oct 03 20:05:58 Again, the Gadget Serial (COM..) has a yellow exclamation mark, and I can connect to the IP address 192.168.7.2. Oct 03 20:06:28 *I cannot connect to the IP address 192.168.7.2. Oct 03 20:07:01 MAEW: Can you ping it? Oct 03 20:07:41 What do you mean ping it? Oct 03 20:08:17 ping the addr 192.168.6.2 from the windows computer Oct 03 20:08:28 Got it, give me a moment. Oct 03 20:12:24 Humpelstilzchen: This is what I get on BBB Shell: https://pastebin.com/U5MvEABL, and it keeps going. Oct 03 20:13:42 On Windows it's like this: https://pastebin.com/ANcruBMe. Oct 03 20:14:04 looks like the connection works... Oct 03 20:14:18 MAEW: what exactly are you connecting to? Oct 03 20:14:23 what service? Oct 03 20:15:02 Service like what? Oct 03 20:16:33 MAEW: When you say that you can not connect - what program do you use? Oct 03 20:17:43 Humpelstilzchen: I use Matlab. Oct 03 20:19:17 MAEW: thats really generic, can you be a little more specific, e.g. what network port does it connect to? Oct 03 20:19:20 I have everything installed. I connects perfectly without microSD, but the problem is when I boot on the miroSD. Oct 03 20:20:08 MAEW: is that a public available matlab script you are running? (link?) Oct 03 20:20:38 test Oct 03 20:20:52 zarzar: failed Oct 03 20:22:51 Humpelstilzchen: Just typing beaglebone_black('192.168.7.2') Oct 03 20:24:35 https://www.mathworks.com/help/supportpkg/beaglebone/ref/beaglebone_black.html Oct 03 20:25:55 MAEW: aah it says port 22 there, did you install package openssh-server on ubuntu? Oct 03 20:26:15 Yes it is. Oct 03 20:26:36 It actually show me that without the IP address. Oct 03 20:27:47 Do you mean installing the openssh-server package from the Shell? Oct 03 20:27:52 yes Oct 03 20:28:11 I'm not sure, I can do it now. Oct 03 20:34:17 Humpelstilzchen: Do I just enter "sudo apt-get install openssh-server" on the BBB Shell (I'm using putty). I assume that I need Internet connection to BBB, right? Oct 03 20:35:48 MAEW: yes and yes. What did you connect putty to? (What did you type in the hostname box?) Oct 03 20:38:33 Humpelstilzchen: I'm using a serial connection with Putty: COM../115200. Oct 03 20:38:45 ok Oct 03 20:39:33 MAEW: "dpkg -l openssh-server" should tell you if the package is already installed Oct 03 20:40:29 Could the openssh-server package be added to my microSD card from Ubuntu terminal, because I'm having trouble connecting the BBB to Internet? Oct 03 20:41:41 OK, it's says this: https://pastebin.com/adrFeCRm Oct 03 20:41:59 ..soo openssh-server is installed Oct 03 20:42:29 MAEW: ok lets try to open putty and connect with ssh to 192.168.7.2 port 22 Oct 03 20:42:36 OK Oct 03 20:44:50 I'm in. Oct 03 20:45:55 MAEW: did you use the username 'debian' and password 'temppwd' to login? Oct 03 20:46:53 No, I use 'root' and the password I set for ROS. Oct 03 20:47:26 MAEW: can you try the debian/temppwd login? Because this is what matlab is using according to https://de.mathworks.com/help/supportpkg/beaglebone/ref/beaglebone_black.html Oct 03 20:50:12 Humpelstilzchen: Access denied with 'debian', but work with 'ubuntu'. Oct 03 20:51:56 MAEW: ok so lets try the call from matlab with username ubuntu and password set Oct 03 20:53:28 OK. I just want to say that with either 'root' or 'ubuntu' things are working on the shell (data acquisition from the sensor). Oct 03 21:03:33 Humpelstilzchen: It's working. This is what I get: https://pastebin.com/MLQ9qQSY. Thank you! I have been trying with 'root' in the past, but it's not working. Oct 03 21:04:05 :) Oct 03 21:04:13 root is usually not allowed over ssh Oct 03 21:05:13 But I work with 'root' on Putty! Oct 03 21:06:16 MAEW: it is allowed on serial (COMx) Oct 03 21:09:21 Yes, that's true. It didn't log me in when I connected to SSH on Putty. Oct 03 21:12:59 Humpelstilzchen: What about the exclamation mark on the Gadget Serial port: https://cdn.pbrd.co/images/GNgTLBU.png? Is this problematic? Oct 03 21:13:24 https://cdn.pbrd.co/images/GNgTLBU.png Oct 03 21:14:02 https://pasteboard.co/GNgUP95.png Oct 03 21:14:25 MAEW: probably meaning that the Beagle does not give you Internet Oct 03 21:16:28 I would ignore it Oct 03 21:21:16 n8 Oct 03 21:44:47 Humpelstilzchen: Thanks a million. Oct 03 22:04:04 I have a beaglebone black wireless, I need to disable HDMI for my uses, but by modifying uEnv.txt to disable HDMI I lose the wireless functions of the BBB wireless! Is there a way to disable HDMI withOUT disabling bluetooth and wifi? Oct 03 22:11:43 https://pastebin.com/xat3dfaE is my testing software for once pass and a u-turn for my electromechical mower. Oct 03 22:11:44 ... Oct 03 22:11:55 How would you change it? Oct 03 22:12:14 I am using a BBG and Motor Bridge Cape. Oct 03 22:16:42 For instance, would you want to use Tkinter for UI or something more? I am running out of "better" ideas. Oct 03 22:34:38 Oh and to maheen: I am sorry for the, "Jump out the window off the bridge," comment. Oct 03 22:34:46 The heat of the moment and all. Sorry. Oct 03 22:36:56 ...okay! Back to the BBB! Oct 04 01:03:34 No Motor Bridge Cape support...come on community? There has to be someone with this awesome Cape. **** ENDING LOGGING AT Wed Oct 04 03:00:02 2017
