**** BEGIN LOGGING AT Thu Nov 16 03:00:02 2017 Nov 16 03:00:38 I don't think vision processing involves gigabytes of data? you can't access such volumes of data in real-time processing Nov 16 03:01:21 I think Nov 16 03:02:56 You could be right about that. Maybe just enough for the framebuffers and a few depth applications. Nov 16 03:03:24 anyway gotta split. zmatt, thanks again for the help and answering all the newb questions! :) Nov 16 03:03:38 the am57xx/dra7xx does have quite a large amount of on-chip SRAM with circular buffering support Nov 16 03:04:23 I suspect those play an important role for passing video data around between systems with low latency :) Nov 16 03:04:31 *subsystems Nov 16 03:05:08 bye.. Nov 16 05:33:46 can i format and make partition on microsd card with the help of this board Nov 16 11:05:05 Hi, I'm still having some trouble finding any packages : could it be the sources.list of my BBB wrong ? If someone is here and has an helpfull hand... Nov 16 15:15:01 hi is there a firewall on the BBB that would block ssh connections? Nov 16 15:30:08 i have a debian embedded board (beagleboneblack) that will drop SSH connections and leave a hung ssh connection until reboot of keys are regenerated Nov 16 15:37:43 Alguien sabe si hay algún proyecto de implementación de la pantalla de raspberry pi 7" para beaglebone? Nov 16 15:54:56 Hi Everyone, I have a little issue with my bbb that cannot update/upgrade packadge anymore (may be the source.list) if so does anyone knows how to fix it ? Nov 16 15:55:25 (I already try to reflash) Nov 16 16:15:31 how do i change ssh settings on BBB? there is no ~/.shh/config file or ~/.shh/known_hosts file Nov 16 16:17:30 my BBB is dropping ssh connections: error: Timeout, server ... not responding. after a few minutes I am able to reconnect Nov 16 16:37:05 does BBB IOT image use dropbear? Nov 16 16:37:28 no Nov 16 16:38:11 openssh like any normal linux system Nov 16 16:39:19 ~/.ssh/known_hosts should definitely exist if you've ever ssh'd from your beaglebone to another device Nov 16 16:40:53 it sounds like you're talking about ssh'ing *to* the bbb though, in which case it's the known_hosts on your computer that matters, not one on the bbb Nov 16 16:41:37 I don't see any plausible way for ssh config to result in dropped connections and unreachability though (and known_hosts definitely isn't related to that) Nov 16 16:41:53 sounds more like network problems Nov 16 16:48:39 does BBB IOT image use dropbear? Nov 16 16:48:43 solved: another device has the same IP address statically assigned Nov 16 16:49:08 I already said it uses openssh, not dropbear Nov 16 16:49:12 zmatt: thanks, the problem was another device has same ip address Nov 16 16:49:13 and like I said, network problems :) Nov 16 16:49:36 zmatt: i should have checked sooner Nov 16 16:49:52 dhcp server does not know about the static address usage of another device Nov 16 16:50:13 some dhcp servers are smart enough to probe ips before assigning them Nov 16 16:50:46 though to be honest, just don't use static ips... or at least don't assign them inside the range of a dhcp pool :P Nov 16 16:53:00 yea i'll have to figure that out Nov 16 17:09:25 Hello World Nov 16 17:10:29 So strange question: What is the recomended way to force the kernel to reboot during bootup? Nov 16 17:11:22 I am working on U-Boot and I need a broken kernel to test a recovery feature Nov 16 17:11:26 Ty_: reboot during bootup? why during bootup? Nov 16 17:11:42 do you not mean a Linux command? Nov 16 17:12:35 I was hoping to simulate a bad kernel image, misconfigured, bit-damage, etc Nov 16 17:13:11 looking for a low-level programmatic way? Nov 16 17:13:27 or hardware? Nov 16 17:13:31 like a module that just calls panic or something Nov 16 17:13:55 yea programmatic Nov 16 17:13:56 whose panic? u-boot's panic? Nov 16 17:14:20 linux kernel panic Nov 16 17:14:37 https://github.com/RobertCNelson/u-boot/blob/master/lib/panic.c Nov 16 17:14:58 I want U-Boot to run to completion, linux to begin to boot, then at some point a soft reset occur Nov 16 17:15:08 https://github.com/beagleboard/linux/blob/cfcb695db3511904a7976b013f22ad5333776016/kernel/panic.c Nov 16 17:15:44 big question in my mind is where you want to inject it. Nov 16 17:15:51 * jkridner is being distracted now. Nov 16 17:16:47 honestly, I don't care. Nov 16 17:17:11 change your init= to a program that will invoke a panic. Nov 16 17:17:59 That would do the job. Nov 16 17:19:05 Oh wait, if the bootloader then swaps the kernel image for another, that image will also panic no? Nov 16 17:19:35 you'd need the bootloader to pass a different init= to the kernel as well. Nov 16 17:20:05 Google: https://unix.stackexchange.com/questions/66197/how-to-cause-kernel-panic-with-a-single-command Nov 16 17:21:29 from https://unix.stackexchange.com/questions/30414/what-can-make-passing-init-path-to-program-to-the-kernel-not-start-program-as-i ... Nov 16 17:21:48 You can custom your Linux kernel and recompile it. For 4.9 kernel, Edit the function "kernel_init" in init/main.c and try to run the following line first: Nov 16 17:21:48 try_to_run_init_process("/bin/sh") Nov 16 17:21:48 In addition, It might be caused by the kernel parameters passed by BootLoader. Nov 16 17:23:22 Nice, I think I will try a custom kernel. Nov 16 17:24:11 It will work with our patch arachitecture, it will be like sending a bomb in the mail. Nov 16 17:24:20 Thank you for the insight Nov 16 18:12:58 you could write a custom init that checks the presence of a file and deletes it and panics, if it doesn't find the file, it passes it off to the real init Nov 16 18:13:37 a little easier than recompiling the kernel ... Nov 16 18:37:52 does bbb have a dns server? if so how do i disable? Nov 16 18:53:17 zmatt: I upgraded a bbg to the latest version (dogtag BeagleBoard.org Debian Image 2016-11-06), and /boot/uEnv.txt still doesn't seem to mention the PRUs. Nov 16 18:56:00 uhh, latest images is 2017-10-10 Nov 16 18:56:02 *image Nov 16 18:56:25 you grabbed the old Jessie image Nov 16 18:58:04 oh Nov 16 18:58:06 pfft Nov 16 18:58:08 I have no idea why that one is still included under recommended images... presumably there's some use for it but I don't know what Nov 16 18:58:15 "for ... blah ... beaglebone green ... blah" Nov 16 18:58:21 that's confusing Nov 16 18:58:21 the first link is the one you want Nov 16 18:58:26 gotchya Nov 16 18:58:27 thanks Nov 16 19:02:40 (even more recent testing images and flashers can be found at http://elinux.org/Beagleboard:BeagleBoneBlack_Debian ) Nov 16 19:07:06 I'll stay away from testing for now so long as what I need is here, but thanks Nov 16 19:49:56 * n8vi smiles as the uio_pruss module loads, and installs old friend am335x_pru_package Nov 16 19:50:48 I do want to learn the remoteproc way at some point, but, neat, these skills aren't obsolete Nov 16 19:57:18 Hello, any tips for reading CAN frames 1 bit at time with BBB? Nov 17 00:14:50 got a PocketBeagle, mass storage is working, I can read the start.htm etc., but network doesn't work. host system is Debian, with ifconfig I can see this on the host: https://pastebin.com/JqKDNrxM but 192.168.6.2 or 192.168.7.2 is not working Nov 17 00:16:28 minicom to /dev/ttyACM0 works, too, so I can login to the beagle Nov 17 00:25:19 ok, loooks like default password for root is not empty as written somewhere on the internet, but I can login with "debian:tmppwd" and then do a "sudo bash" to get to root Nov 17 01:24:16 works with Windows 10 as a host and the Windows drivers, I don't like Linux anyway **** ENDING LOGGING AT Fri Nov 17 03:00:03 2017
