I'm posting a little more info 'cause no-one took the bait:

And now it's truly well hung.
Problem with init ? The wait reboot is compiled ? The reset vector ?

ML405 failed reboot

2008-04-24 Thread Guillaume Dargaud 
Now that my Xilinx card is operational with Kernel 2.6.24 and a 
buildroot/busybox/uClibc config, I'm getting on the application side.


First hitch: I can't do a soft reboot of the card:

# reboot
The system is going down NOW!
Sending SIGTERM to all processes
Requesting system reboot
[  434.713999] Restarting system.
[  434.7[  434.718123]   Signal: 4
[  434.718133]   Code:   30001
[  434.718144]   Addr:   c74cbdc8

And then it just hangs.
I also tried the additional -n (no sync) and -f (force) without difference.

Design problem ?
Any other way to force a reboot ?
