Hai Jingyang,

Thanks for the reply. we tried as you suggested with above steps but the result is same i.e not showing any values in that address .

I checked after linux boot with devmem command also.

Here i attached the steps in u-boot console.

But the same flow is working fine in xilinx board ,i'm able read the data from that address .

Regards,

Manikanta
