I have an Atmel board, precisely an Atmega1280. I uploaded my code on the board and I want debug it to take a look at the stack memory. I just have the mini usb cable for the communication.
I read that JTAG is also a debugger but I don't understand what exactly it is and if works with my cable.
Hence, my question is: Is there any debugger for Atmega1280 that work also with mini usb cable possibly free? If yes, what are they? Where can I find them?
