Hi There,

 

 I have a custom board of and soloX and a SoloX sabre SD, both have the has a similar uboot build with only uart1 and the qspi enable. I have tried booting a simple MQX "helloworld" on my custom board and it failed. I am puzzle by this situation, because i have the same uboot setup for my SoloX sabre SD, and it work fined.

i found that the different between my custom board and the SoloX sabre SD is on the accessing the RDC register. RDC register access totally failed on my custom board.

this link below might shed some thing about the nature of my problem:
