WRAP Geode CPU support for HW watchdog and LED's Hi, apart from all the hype about FreeBSD 6.1 for m0n0wall, I'm working on a project based on the WRAP platform where the 4.11 based m0n0wall software is more than adequate. I was looking though for LED and HW watchdog support but couldn't find it, so I ported it back from more recent BSD versions. I've attached the required kernel changes as a patch and also provide a test program wdtest.c, which simply activates the watchdog and lets the WRAP box die after 8 seconds. The actual 'kick the dog' part in form of a watchdog daemon is still missing though. I'm still looking into how to do this best. Any feedback is of course welcome. This is a first shot at the problem and it seems to work for me, but of course limited to WRAP boards only. The other little program, led.c, allows the 3 LED's of the WRAP board (from PC Engines) to be turned off or on individually. You'll need to create the character device special file! for t! he watchdog and LED's to be set: mknod $MWROOT/dev/fido c 200 0 Any feedback is of course welcome. Best regards, Marcel

Hi,

apart from all the hype about FreeBSD 6.1 for m0n0wall, I'm working  
on a project based on the WRAP platform where the 4.11 based m0n0wall  
software is more than adequate. I was looking though for LED and HW  
watchdog support but couldn't find it, so I ported it back from more  
recent BSD versions.

I've attached the required kernel changes as a patch and also provide  
a test program wdtest.c, which simply activates the watchdog and lets  
the WRAP box die after 8 seconds. The actual 'kick the dog' part in  
form of a watchdog daemon is still missing though. I'm still looking  
into how to do this best. Any feedback is of course welcome. This is  
a first shot at the problem and it seems to work for me, but of  
course limited to WRAP boards only.

The other little program, led.c, allows the 3 LED's of the WRAP board  
(from PC Engines) to be turned off or on individually.

You'll need to create the character device special file for the  
watchdog and LED's to be set:

mknod $MWROOT/dev/fido c 200 0

Any feedback is of course welcome.

Best regards,

Marcel
