Retrieving usercode from binary configuration image

Hi Dave,

it should work to have the custom header below the regular rbf and sending the rbf address as update start address. The loaded application can retrieve the last loaded flash address from the remote update controller and retrieve the custom information below it.

Suggested reading about remote system update:

with design files (unfortunately schematic design)

also with desugn files

RSU chapter of the respective FPGA handbook. There are some detail differences in RSU controller commands, port widths etc. between devices. You can easily miss things like a required right shift of the address port. The handbook is the ultimate reference in this regard.

Best regards,
