Retrieving usercode from binary configuration image

Hey Frank,

Now I want to add usercode decoding to a remote system update package

I took a slightly different approach to validating images for the FPGAs on this board;

In this document

I describe how I use U-Boot's mkimage tool to add a header to the .RBF files. This allows me to use mkimage to get a summary of the image too.

My MAXII configuration controller also reads this header before allowing FPGA configuration, but that would be optional if you used a processor to validate the header, and then write the .RBF contents to flash.

This saves having to know anything about the .RBF format.

Cheers,

Dave
