How can I get PJ2 checksums without a connected programmer, for example directly from a PJ2 file?
Environment (PJ2) checksum and HEX file checksum inside *.PJ2 file can be got by direct read from the PJ2 file (as binary image) at fixed offsets as follows (2 bytes for each, LSB first): PJ2 file checksum: 0x02 Hex file checksum: 0xA5 The Environment (PJ2) checksum and the HEX file checksum stored inside a *.PJ2 […]
