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?
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.
