Beaglebone watchdog timer

Hello,

I am developing an application to transfer MJPG video over the
network. The application should keep noticed a watchdog every frame. I
developed this application in BeagleBoard where I had to compile the
kernel enabling TWL4030 in order to use the watchdog.

Currently I am using the program in a BeagleBone with Angstrom and the
kernel 3.2.6+. The program works fine except for the watchdog which
doesn't do anything.

Do I have to recompile the kernel enabling any option as I had to do
when I developed our program in BeagleBoard?

Thanks,
Daniel

Hi,

I've been looking for a git source to clone the kernel,
but I hadn't have success finding one to compile with the
options specified in:
http://processors.wiki.ti.com/index.php/AM335x_PSP_WDT_Driver_User_Guide

Does anyone know where can I find one updated git source?
I have also tried the Sub-repository specified in the thirth thread of
this google group but it broke while building modules.

Can anyone provide acurate information about a git source with
configuration files?

Thanks,
Daniel

PSP release is accessible at
http://arago-project.org/git/projects/?p=linux-am33x.git;a=summary

It supposed to have support for WDT.

Hi Hiremath,

Thanks for your help. I tried the git source, but it is a Linux 3.1
branch, which has some usb issues under BeagleBone. Since I have
suffered them in my webcam application I prefer to discard it.

Also I found that http://elinux.org/BeagleBoardUbuntu#Demo_Image
talks about the usb issues regarding to 3.1 kernel.
I tried the BeagleBone git source explained in that document. It's a
3.3 Linux branch, but after building and installing it in the
BeagleBone it stucks at the begining of the boot process.

The issue I am trying to solve is that watchdog timer doesn't work in
Angstrom 3.1 not 3.2 kernels,
so I try to compile it to have one with the options specified in
http://processors.wiki.ti.com/index.php/AM335x_PSP_WDT_Driver_User_Guide

Any ideas?
Thanks

Solved. I moved from Angstrom to Ubuntu 11.10 and everything worked fine after installation, including the watchdog timer.
