How can I get PJ2 checksums without a connected programmer, for example directly from a PJ2 file?
Answer
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 file can be obtained by reading the PJ2 file directly as a binary image.Both checksums are 2 bytes long (LSB first) and are located at the following fixed offsets:
PJ2 file checksum: offset 0x02
HEX file checksum: offset 0xA5
