Hi ManthanWankar,


I was able to execute bridge enable in Uboot user space using GSRD build and can detect the same sys id from the System ID Peripheral Intel FPGA IP which connected to 0xFF200000.

If I didnt perform bridge enable, the system will reset/restart after I execute md 0xFF200000 in Uboot user space.


May I know which device tree file which you change for uboot referring to the link below:

Is it possible to compare/test with GSRD before any changes being made?



Thanks.

Regards,

Aik Eu
