7.3 avr-gdb Debug (simavr)

With debug support enabled you can use avr-gdb to debug the code used in the simulator. Use the configuration window to choose between MDB (MPLABX) or GDB to debug AVR microcontrollers.

Use avr-gdb with the .elf file as the parameter:

 avr-gdb compiled_file.elf

and the command below to connect (1234 is the default port):

 target remote localhost:1234

Graphic debug mode can be made using eclipse IDE with Sloeber Arduino plugin.
