how can I use the TWR-KV58F220M Boards to Debug an external Board

[weijia]

I have 2 kv58 boards, one has internal debug probe so that I can use usb port connecting to my PC to debug it. Another one needs a external debug probe to debug it. 

So I am looking for a way to debug the second board by using the first board as a debug probe as I do not have an external debug probe.

I found a nice tutorial to do what I exactly want, but it is for LCPXpresso referring below (I need know how I can config the jumper and which SWD port I can use as the below link did):

Hi weijia,

The JTAG port(J13) of TWR-KV58F220M direct connect to on board KV58. So I am afraid you can not use J13 connect to external chip.

Maybe you can disconnect J19 and J20, then use signal on Pin2 from the onboard debugger.

Best Regards,
Robin
