my board for mx28 has one nand flash with 128MiB and DDR2 SDRAM with 64MiB
I set what as fellow ,my logo file is :
NAND read: device 0 offset 0x200000, size 0x400000
4194304 bytes read: OK
* mem_start = 0x40000000
* mem_size = 0x04000000
* kernel: cmdline image address = 0x41600000
## format 00000000 ...
Wrong Image Format for bootm command
ERROR: can't get kernel image!
