How to change the value of CCSR on P2020RDB-PC board

Hi,

 

We got a P2020RDB-PC board, and now we want to change some configuration of it.

From P2020RM, we know we need to write to configutation, control, and status registers (CCSRs).

Now we can read the value of CCSR in the uboot by command md ffe00000+offset address.

And we try to use command mw in uboot to write to CCSR. It seems not working or the value is back to default after reset the board.

Is there a way we can change the value in CCSR permenantly? How can we do it?

Thanks in advance.

 

Regards,

Hu
