Simulating Using SimulAVR && Debugging Using GDB

Open a terminal and execute the following:

simulavr -d atmega32 -f AVR_PROJECT.elf --gdbserver

In another terminal, run:

avr-gdb AVR_PROJECT.elf

In order to begin debugging using GDB, connect it with SimulAVR using the following command. Port 1212 is the default port for SimulAVR; make sure it matches the port returned by SimulAVR upon starting it.

target remote localhost:1212

Symbol Table is read by GDB by default if -g compiler flag was used to add debugging symbols.

Common GDB Commands

1. To place a breakpoint:

   break LABEL_NAME

2. To continue executing until breakpoint is reached:

   c

3. To print a variable's value (if it is a pointer for example):

   print *PTR_NAME

4. To single step in C code:

   n

5. To switch code layout from C to Assembly:

   layout asm

6. To single step in Assembly code:

   stepi

   si

7. To switch code layout back to C:

   layout src
