hi. i have to calculate the crc checksums of a virtex 4 bitstream. there are two ckecksums: one direct after the configuration frames and one at the end of the bitstream. no i want to know, if all bytes are used to generate the checksum? i already implemented the an algorithm, whch works fine with an test input. but when i try to recalculate a checksum of a bitfile, it does not match ... the algorithm i use is from rocksoft:
i use it with the parameters for crc32: Poly : 04C11DB7 initial value 0xFFFFFFFF input is reflected checksum reflected on end of generation checksum xored with FFFFFFFF
maybe you can help me.
