I brought the new arduino due board and I had written a few programs on it. Now I am having the JLink debugger from segger and I want to use it to download programs into the arduino. So first I am trying to read the bootloader from my controller then I will write and transfer programs into it using JLink. I am unable to do this. The JLINK JTAG header is 20Pin to which I had connected the pins from the arduino.I had connected the JTAG Pins as follows:
JLink Pins Due Pins
VTref(Pin 1) 3.3V Vcc
TDI (Pin 5) TDI (10 pin Debug Port pin
TMS(Pin 7) TMS (4 pin Debug Port pin 3)
TCK (Pin 9) TCK (4 pin Debug Port pin 2)
TDO (Pin 13) TDO (10 pin Debug Port pin 6)
RESET (Pin 15) Reset (4 pin Debug Port pin 4)
GND (Pin 4) GND
So my question is :
Are these connections ok?
Can anyone give me the standard 20 pin JTAG connector pinout?
Is JLink compatible with SAM3X8E?
