I wrote a code for atmega2561. The code's memory usage in prog memory is almost
153000 bytes.
The problem is, code doesn't work properly. the mcu getting reset or something
like this... I think compiled
code calls wrong addresses in somewhere of the memory. When I comment some of
part of text messages in the memory, the total memory usage become 126000 bytes
and the code works good....
I had also had a problem with eicall in winavr. I had fixed it like this:
EIND = 1;
asm("ldi r30,0x00");
asm("ldi r31,0xf0");
asm("eicall");
I guess avr-gcc doesn't set "EIND = 1;" for atmega2561 while compiling.
So i cannot using the other part of mega2561 (nearly 128K) because of this
BUG.
Please somebody fix it, it is very urgent...
Thanks....
