Module CRCs are implemented as absolute symbols that get resolved by a linker script. We build an intermediate .o that contains an unresolved symbol for each CRC. genksysms parses this .o, calculates the CRCs and writes a linker script that "resolves" the symbols to the calcScott, can somebody from FSL test that on 32-bit and Ack it ? Thanks ! Cheers, Ben.It boots for me on e500mc and I can insert modules.
But does perf work ? :-) Cheers, Ben.
