I have been trying to get U-Boot and Linux running on the AMCC 440EP
"Bamboo" reference board. Most U-Boot commands are working. However,
I've got problems about reset command and switch.
First, reset command does not work except after cp.b command performed
(i.e. cp.b 100000 fff80000 80000). I don't know why it works well
after cp.b command. Reboot command in Linux doesn't work neither.
U-Boot version is 1.1.3 and Linux kernel is 2.6.13. Is it related to
the same reason?
Second, the reset switch does not work. I've been confirmed that
SYSTEM_RESET line is getting pulled down when I push the reset switch.
When I try to get PIBS instead of U-Boot on the same board, the above
problems haven't happened.
Had the problems been discussed before in this list? I can't find any
of conversations about them. If so, give me the url please.
Let me know how to fix them up.
Thanks in advance,
