Hello,
I have this problem. I built SD2IEC v1.2, flashed chip ATMEGA644PA by a bootloader (newboot-0.3-sw2-m644p.hex), set up fuses (low - E7, High - DA, Extended - FD).
Then I tried to load firmware (sd2iec-0.10.3-sw2-m644p.bin) from my SD card, but uploading doesnt work.
Anybody know, what could be wrong ?
Thanks,
David
