ATMEGA2560 Compile Question

Hi, 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. Wynand Weyers This message was checked by MailScan for WorkgroupMail. www.workgroupmail.com _______________________________________________ AVR-GCC-list mailing list AVR-GCC-list@... http://lists.nongnu.org/mailman/listinfo/avr-gcc-list |

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.
