ATMEGA328p - avr_sadly_crashed #183

Closed ricardojlrufino closed 6 years ago

Running...

simavr -m atmega328p UsbConnection.ino.elf

I got this error:

CORE: *** Invalid read address PC=1cc2 SP=08e4 O=918c Address 859e out of ram (08ff) avr_sadly_crashed avr_gdb_init listening on port 1234 ^Csignal caught, simavr terminating

I compiled using Arduino IDE - Uno Board. I am sending the folder that Arduino generates with the compiled files

USBTest.tmp.zip

Well, this usually just means there is a bug in you firmware. Under this condition simavr activates the GDB backend and waits debugger connection using TCP on the localhost:1234. You can setup your IDE (Eclipse or CodeBlocks ..) to start the 'remote' debug session using this address, and then trace the situation leading to the above error.

It was what I imagined at first, but the same code is running from Arduino UNO. I think it might be some mistake to access the EEPROM, I'll investigate more calmly, trying to debug.
