[Avrora] How to increase the RAM available

[Daniel Minder]

Hi,

Change ATMEGA128_SRAM_SIZE in avrora\sim\mcu\ATMega128.java and re-make
Avrora.

BUT: At the beginning of the init code for each AVR program the stack
pointer is set to the end of the RAM which is hardcoded. So, if the
error is caused by a stack overflow increasing the RAM size in Avrora
won't help, but you have to change the program as well. I don't know
how, but maybe the "-minit-stack=N" gcc parameter works. Or you could
try to change the RAMEND define, probably in iom128.h, which is
somewhere in the avr includes.

Best,
Daniel
