Hi, The problem due to MAC address. I fixed by reading MAC address from flash, write to FEC_ADDR_LOW/HIGH, then dhcp, boa,... just worked fine. However, if I turn off the board for a while (15s), the boot progress just hang right after u-boot transfers the control to linux.

I tried to set value to a IO port in setup_arch() (...)m68knommu/kernel/setup.c but that function has not executed. So may the problem is from bootloader or kernel? How to confirm the kernel is executed or not? Any suggestion about debugging it. Thanks in advance. _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
