Hi ManthanWankar,


I was following the GSRD from Rocketboards to boot up from QSPI flash. The quartus version I used was the same version(23.2Pro) from Rocketboards building bootloader.


I didnt make any changes to the GSRD/GHRD but only built accordingly and flashed it into the board. I notice you have make some changes to the GHRD and the address for your sysid is different which does not start with offset 0x00000000.(When query with md in Uboot user space, it will be 0xFF200000). Seems like your case will need to query from 0xFF200140, you can try to check on that.


For troubleshooting purpose, I suggest to use the default GSRD/GHR without modification first then bridge enable and query the sys id to verify the bridge is working.


Thanks.

Regards,
