Hi ManthanWankar,


Is there any error return when execute bridge enable?

If there is no error then when peform md 0xff200000, the system will reset?

Are you using the GSRD from building bootloader to test before any modification?

I can try to test the GSRD on my side but will need some time to do that.


Thanks.

Regards,

Aik Eu

    no error returned while bridge enable

    yes it will give a data abort error and the system will reset.

    yes i am using the GSRD only have changed the memory size from 1GB to 2GB else every thing is the same

    the default device tree does not have fpga bridges in it's device tree node so have added those.
