Hi.. This is Billy Jang.
I just give a simple comment for you. This message occurred in the absent of NAND flash in the board. If you remove the flash memory in the EVM board, you can get the same message. Please check your hardware schematic and the component value. etc. In these days, I have changed the flash several times. I met your case in several times.
