I'm trying to get firmware designed for 8k RAM down to 4k RAM. avr-size reports:
Program Memory Usage : 65160 bytes 46.8 % Full Data Memory Usage : 5679 bytes 69.3 % Full
I ran "avr-nm -t decimal firmware.elf" and added up all the "B" type objects, but they only come to 3828. How can I find where the rest of the RAM is being used?
This is going to be a real challenge...
