In contrast to normal use (USB only), for debugging there are two separate wiring changes to do: connecting the ISP headers connecting the JTAG header to the respective pins on the ArduinoД¬onnecting the ISP headers is straight forward: Pin1 on the Dragon connects to Pin1 on the Arduino Mega2560 and so on. this one restore the fuses to the default state. This isn't an issue because all of the afore mentioned devices have ISP capabilities, but it requires some additional steps to get back normal operation after debugging: flash a new arduino bootloader on the device, e.g. Because of that it is a necessity to use an ISP (in system programmer) to do the debugging. Additionally it seems to be required to overwrite the bootloader on the MCU. Important:** To use a JTAG Debugger in conjunction with the ATmega2560 it is required to change the fuses of the MCU. I tested debugging RIOT on the Arduino Mega 2560 using an AVR Dragon. There may be other options as well, but I can't comment on how well they work. AVR Dragon (Note: This debugger is out of production.) AVR JTAGICE mkII JTAGICE3

There are several options for this MCU/board: Atmel-ICE (Note: A version of the Atmel-ICE without case (just the naked but fully assembled PCB) is currently the most affordable option. To use the JTAG debugging on the Arduino Mega 2560 an external JTAG debugger is required. The ATmega2560 MCU supports JTAG debugging. More pins can be used for hardware interrupts using the Pin Change Interrupt feature.

We use the open avrdude tool to write the new code into the ATmega2560's flash After flashing RIOT you can without any intermediate steps just go over to flashing Arduino sketches again.ДЇlashing RIOT on the Arduino Mega2560 is quite straight forward, just connect your Arduino Mega2560 using the programming port to your host computer and type: NOTE: In case you are wondering if flashing RIOT on your Arduino Mega2560 will overwrite the Arduino bootloader: you can be reassured. It is like many Arduinos extensible by using shields. It is based on Atmel's AVR architecture and sports an ATmega2560 MCU. There are pin mappings to atmega8 and atmega 168328 as well.The Arduino Mega2560 is one of the larger Arduino boards.

External supply for arduino mega from range 7 12 volt is given with this port. The arduino mega 2560 is a microcontroller board based on the atmega2560 datasheet. Reset input a low level on this pin for longer than the 4 clock cycle will generate a reset. Below is the pin mapping for the atmega2560. See also the mapping arduino mega 2560 pin diagram.
