[beagleboard] syslog 'DHCPDISCOVER on eth0' when using wireless
I am using RCN debian 8.0 jessie on a beaglebone black. I am using a usb to wifi adaptor, and my ethernet port is unused.

Re: [beagleboard] Re: archive keyring on elinux is not found
thx, robert. my /etc/dogtag said it wasn't that old: 2014-11-19. the keyring update made my apt-get update error go away. great. suggestion: add the kernel update instructions in the same doc, too. kernel update with apt-get went very smooth. I wonder whether there is a way to apt-get to most recent kernel, rather than having to know the linux-image-... details . then again, maybe this is now fixed, too. not sure if this matters, but sudo dpkg -i rcn-ee-archive-keyring_2015.01.28~bpo70%2b20150213%2b1_all.deb still complains. thanks again, robert. /iaw On Sunday, March 1, 2015 at 8:33:25 PM UTC-8, RobertCNelson wrote: On Sat, Feb 28, 2015 at 10:58 AM, ivo welch ivo...@gmail.com javascript: wrote: actually, more generic. my BBB is running Linux 7.8 (wheezy).

[beagleboard] Enable / disable watchdog timer ?
Hello all; It seem that the watchdog timer is automatically enabled when the USB-OTG port is connected to a PC. I am running the latest Debian release, and I am wondering if is possible to disable watchdog after boot. Or after a user login ? Do I use something like “close(watchdog)” in a login script ? Or is there another/better way ?? Thanks; Bill No one could make a greater mistake than he who did nothing because he could do only a little.

Basically when the USB-OTG port is connected to my PC, pulling the “power” signal low or removing the +5V supply causes the BBB to power off briefly and then re-boot. It seems to me that there must be a way to disable this, assuming that it is a “feature”. Thanks …. No one could make a greater mistake than he who did nothing because he could do only a little.

[beagleboard] Re: Enable / disable watchdog timer ?
I just tried with latest debian and ti-kernel installed. Powered up with 5V and usb otg connected to pc. Remove 5V: michiel@arm:~$ Broadcast message from root@arm (Sun Mar 1 20:38:52 2015): Power button pressed The system is going down for system halt NOW! clean shutdown and stays off. This is the pmic input driver sending an 'pwr_btn' event which is catched by acpid which does a clean shut down (see /etc/acpid/...) So this seems easy to configure. Only it doesn't react the same as yours. Now I'm going to look what you mean by watchdog (a black one? type beagle:) regards, Michiel -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Re: FFT on PRU
It's unlikely that you'll find a complete solution running on PRUSS, since PRU assembler has very limited math capability (+, -, * and boolean operators). Division is not supported (except by factors of 2) and trigonometry is far beyond the scope. But it should be possible to generate a hybrid solution with look-up tables, pre-computed on the host CPU and the PRU doing the simple math. I haven't seen such a solution yet. Happy coding, share your results! BR -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Beagleboard xM Crosscompiler
Hi there everybody, I feel amazingly stupid and I'm close to jump out of the window because of this so I'm begging you, sitting on my knees to help me out here! I am running Windows 7 64bit and also have a virtual box running ubuntu now. I will need to write a kernel module for the Beagleboard xM running embedded ubuntu. For that I would like to set up a cross compiler. There are plenty of tutorials out there how to set up eclipse with code sourcery but if I do what they tell me to do I have codesourcery in my windows path variable but in eclipse I can only choose between Cross ARM GCC-, Cross GCC- and Microsoft Visual C++-Toolchain instead of the sourcery one. If I follow other tutorials for other toolchains and what not I always come to some point where things happen that shouldn't happen according to the tutorial. As I said I'm begging you for a tutorial that helps me to install the toolchain, set it up with whatever IDE and write a hello world program to get started. Please please please prevent me from going mad!

So I tried fixing things myself but think I deleted them. Now I can't connect to the BBB at all. I was able to start it with a monitor and get a terminal, since the graffics won't load. But nothing with network works, so I don't know how to re-install anything. What can I do to get my system running again? I don't have any files that I need to keep.

[beagleboard] BBB reboot to Angstrom while running custom build OS
I currently have a Custom build OS that I load to BBB via UART serial connection. After about 1-3 Min the Beagle will reboot and load Angstrom. The OS is still in development, but is stable, and is frequently downloaded. Setup: powered: USB connected to computer Serial: tty via USB converter on the J1 serial connection downloading OS and booting BBB with bootm command OS boots and I can utilize the shell for a shot time 1-3 Min before the Beagle reboots to Angstrom Any help is greatly needed and appreciated -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

RE: [beagleboard] Re: Enable / disable watchdog timer ?
Hi Toni;
I think I have it figured out.
I have an image that works and one that doesn’t.
Watchdog Not enabled:
Linux beaglebone 3.8.13-bone47 #1 SMP Fri Apr 11 01:36:09 UTC 2014 armv7l
GNU/Linux
Watchdog enabled:
Linux beaglebone 3.8.13-bone50 #1 SMP Tue May 13 13:24:52 UTC 2014 armv7l
GNU/Linux
Image “bone47” works like yours does. Clean shutdown with no reboot and no
“watchdog enabled” boot message.
It would appear that this was changed by version “bone50” sigh
Thanks to Google, I found a code snippit, that should work.
dev = WATCHDOGDEV;
/* Once the watchdog device file is open, the watchdog will be activated by
the driver */
fd = open(dev, O_RDWR);
if (-1 == fd) {
fprintf(stderr, Error: %s\n, strerror(errno));
exit(EXIT_FAILURE);
}
/* The 'V' value needs to be written into watchdog device file to indicate
that we intend to close/stop the watchdog. Otherwise, debug message
'Watchdog timer closed unexpectedly' will be printed
*/
write(fd, V, 1);
/* Closing the watchdog device will deactivate the watchdog. */
close(fd);
==
I just have to run it after login (I think).
Later;
Bill

Ok, when I powered up with 5V and usb-otg connected to pc and I shortly press
the power button I can replicate: clean shutdown and instant reboot
Don't know where the reboot is coming from.
here's pmic:
[ 2.897350] input: tps65217_pwr_but as
/devices/ocp.3/44e0b000.i2c/i2c-0/0-0024/input/input0
wrt. watchdog: I assume you mean /dev/watchdog I don't think I have it active.
