Hi,
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,
Youngchul Bang
