Using ulink2 with nrf52840 and keil

[MOHAMED AHMED ALI MAHMOUD ELSABAGH]

I am trying to flash the blink example from SDK v15 into my custom nrf52840 board, I am using pc10056 example.

I connected my ulink2 to swdio, swclck, gnd and vcc of my custom board and I can see on my debug settings but when I try to flash I get Invalid ROM error, I tried to change 

Here are my settings

Hi,

In general we do not support U-Link, and recommend using J-Link debugger that is provided on-board on our DK. The debugger on the DK can be used for flashing and debugging external board through "debug out" port.

Maybe this thread is of any help for you?

Best regards,
Jørgen
