Re: [avrdude-dev] CRC check

[idefixx]

Hi guys! 
Thanks for your help! The combination on avrdude on srecord works great! I'm 
very happy about these useful tools.
But there is one thing I'd like to ask for: If I create a .hex file that writes 
the CRC16 checksum to the last two addresses of the EEPROM, avrdude always 
rewrites the entire eeprom, instead of just writing to the desired two 
addresses. If there is data stored in the EEPROM that I must not overwrite, I 
always have to read the EEPROM content to a file first, insert the checksum 
with srecord and then write the file back to the EEPROM. Wouldn't it be 
possible to make avrdude to perform the programming only on the addresses given 
in the .hex file? Actually this should be possible, as the avrdude terminal 
mode also is able to program single memory bytes without changing other bytes.
Or, if there is a special reason to always start a programming cycle from 
address 0x0000, would it be possible to enable avrdude doing single byte 
operations similar to the terminal mode, but outside the terminal mode?
Regards.
