Segger J-Link 9-pin Cortex-M Adapter has a 10-pin debug connector specified by ARM (Key pin. physically blocked on debug connector.)

Now i have removed the blockade on pin 7 and connect it to the Arduino Due 10-pin connector (referred as JTAG).

But why is there still a the 4-pin (referred as DEBUG) connector?


Hello ctbenery,

That 4 pin header (DEBUG) is a serial wire debug protocol (SWD) connector. It is another simpler protocol that only needs the data and clock lines to talk via serial between the SAM3X8E and the debugger.

In reference to dealing with surface components on the Due, I would recommend to be very careful. It happened to me twice that a capacitors just pop up the board and where hard to find in my workbench floor :). Regards!
