Hello ALl,

 

I am trying to connect J-Link probe to J19 on FDRM-K82F board, so far I cannot connect, my probe is working since i can connect to K20 MCU on same board.  I remove jumpers J6 and J7 as  J17 as well, As a desperate I also remove J8 but it cannot connect after all. I am powering using USB port (not Open SDA port).

 

Here is the output for K20 sucessful connection
