calculation, the parallel CRC data is 120 bits wide. Before going any further into the topic of parallel CRC, I’ll briefly review modulo-2 polynomial arith- metic. A polynomial is a value expressed in the following form: where p(i) = {0,1}. Polynomial addition and subtrac- tion ope...
Another method would be to exclude the Bootloader checksum from your CRC calculation. Access to this checksum is thru a pointer Bootloader_ChecksumAccess, once again, found in file Bootloader.c. I will say, I am confused about your statement:If I disable the bootloader component in the schemati...
