Does anyone know how to solve this problem?
What does your memory map look like? Maybe you are overwriting data or code needed by U-Boot?
Also, consider problem number 1: memory errors dues to incorrect RAM initialization.
I've considered that but unless I'm missing some config item, that looks good. I've got 32MB ram: arch_number = 0x00000186 env_t = 0x00000000 boot_params = 0xC0000100 DRAM bank = 0x00000000 -> start = 0xC0000000 -> size = 0x02000000 ethaddr = 00:08:EE:00:63:B2 ip_addr = 192.168.0.13 baudrate = 115200 bps
My TEXT_BASE starts at 0xc1fc0000 and I'm loading at 0xc0f00000 (~1.2M)
