External J-LINK to flash nRF52840 DK chip

[Lewy2552]

I am currently using a J-LINK EDU Mini to try and learn how to use an external device to flash the nrf board. I am running into trouble because I have connected my external J-LINK to my debug-in pins on the board, but segger embedded studio/ J-LINK commander are both having a problem connecting to the target. What am I doing wrong?

I am sorry that I post my question on this forum because I cannot find a button to post.

I also use a J-LINK EDU mini to flash the RAK4631 board. During J-Link Commander, I cannot open file "C:\demo\seggerdemo.bin 0x0" as the video instruction.

www.segger.com/.../

How can I open that file?

Can anyone know that problem?
