I created a modified eeprom.h file with the fix for this.  It has been submitted, but has not been integrated into WinAVR yet.
I can send it to you if you want it.  Contact me directly.

Subject: [avr-gcc-list] ATMEGA2560 Compile Question



I developed software for the ATmega2560 using an old version of WinAVR (20070525) 4.1.2, it worked fine until I reached approximately 60% of the program flash, using Optimization for size (S). I realized that I need to use the latest WinAVR (20080610) 4.3.0 so I upgraded and re-compiled. I found a lot of “out of program space errors” and resolved those by using the attribute to compile the referenced function calls in the lower .text section. The problem that I have is that the library functions such as the eeprom_write_block and printf also has this issue.


Do you have a patch which accommodates these function calls, and if not do you plan to support this?


I know there was discussions around the ATmega2560, sorry if I missed a similar question.


Many thanks.
