Debugging D11 firmware in Atmel studio

• Compile the D11 sketch from Arduino IDE with verbose output on compilation enabled (there is a checkbox under files/preferences to toggle it)
• The last line before uploading should be similar to

".../4.8.3-2014q1/bin/arm-none-eabi-size" -A "..../arduino_build_383249/I2C-Motor-bridge-D11.ino.elf"

• Copy the path of generated elf file
• Don't close the Arduino IDE (otherwise the temporary files will be discarded)
• Open Atmel Studio
• From File menu, select Open/Open Object file for debugging
• Paste the elf path into "Object file to debug" field
• The paths resolution should be automatic since we are compiling on the same PC.
• Enjoy 😄
