CVAVR C Compiler (generates *.eep EEPROM files)
-----------------------------------------------------------
I am having great difficulty calculating the EEPROM checksum. I am assuming this is Intel Hex Format. Am I right?
If so, basically you add the 20 bytes before the checksum (16b data, 2b address, 1b record length, 1b record type). Then you do a modulus 256d. Then subtract this from 256d. Right?
MED17 functional description docs will help with overview of the EEP handler, but not the checksum routine. Usually it is best to go through the front door with coding tools rather than try to change EEPROM (actually dataflash on most Tricore) directly. Given time I could probably locate the checksum routines and reverse them, but it. This is the EEPROM IMMO OFF solution for newer ecu and cover all EDC17 and MED17 version, for AUDI VOLKSWAGEN SEAT SKODA AND MORE. WORK ON ALL EEPROM EDC17 MED17 FILES 32KB, 64KB or 128KB.

Anyone help here?
The Why: I need to make a custom EEPROM programming software, so when I change the EEPROM values I need the checksum to be calculated. Right now, I am simulating this in MS-Excel by importing a *.eep file, parsing it, and seeing if I can come up with the same checksum the compiler did.
All the checksums of line addresses greater than 256 are off by 1 (why?) and all the checksums of line addresses equal to 0 are just completely wrong.
