i've got raw msp430 code extracted from a target device. i'd like to disassemble it. msp430-objdump requires the file to be in one of many file formats; e.g. symbolsrec, srec, tekhex, binary, ihex. i guess i need to write a converter, but i can only find a spec for the srec format. anyone know where i can find the spec for the other formats? or is there a converter that'll take as input my ascii hex file and a starting address and produce one of these formats?? many thanks.
