Retrieving usercode from binary configuration image

Hello Dave,

thanks again for your comment.

I can't change the rbf header format at will because it must be understood by the hardware FPGA configuration controller. RSU controller "pof checking" is an optional consistency check step before rebooting the new application image. Originally it checks only for a header with valid CRC. Configuration with a corrupted image or an image for a different FPGA type is rejected by the hardware configuration controller anyway. But an image for a different instrument using the same FPGA type could be loaded accidentally. The additional usercode validation reduces the risk to boot a wrong image.

Alternatively, additional information can be put in an unused configuration image part. But it would require additional manipulation of image files.

Regards,

Frank
