JIC file format structure

I have a customer that wants to know how do they determine where the actual flash data begins after the header. Years ago they wrote code to use a processor to write .jic files into serial flash dev...

I'm Steve's customer. Attached is an image of my .jic file. I found a mistake in my .jic file generation. This is the corrected file and I now believe the header is 163 or 164 bytes. Can somebody tell me based on this image where the FLASH data begins? I thought that it was the first FF but this does not seem to be the case. I have tried to set up the file generation options to match the design done in 13.1.

As another data point, it appears that the FPGA is reading in the file but rejecting it based on some error in the file.

Thanks,

Jim C.

    hello ， distrub you .

    i want to look for the CRC of JIC file ,but I search for many post ，it's not a sucessful answer，see yours .jpg file , I want to ask you something 。

    THANK you
