Hi !

My Application is using the EEPROM memory and defines some constants in it. How do i modify the makefile, that it generates the .eep file with the EEPROM values in it? With the default makefile there is no output for this file.

Regards,

Dirk

As far as I know, this is done with avr-objcopy. Don't know the section name to extract, but I'm sure you can find it with a web search.

Thanks Christian, sometimes the things are so easy...

Code: Select all

main.hex:   main.bin
   rm -f main.hex
   avr-objcopy -j .text -j .data -O ihex main.bin main.hex
   avr-objcopy -j .eeprom -O ihex main.bin main.eep

This gives you main.hex and main.eep .

Regards,

Dirk
