Cant program the development-kit board nrf52, but I'm able to program custom boards with it

[navarrocantero]

Hello guys I'm using windows (10) using parallels in a virtual machine in mac (high sierra), all in its latest version.

The board is a PCA10040 V1.1.0. with the bootloader updated to the latest version.

I'm using the latest Jlink too (V6.32d).

The problem I have is that I can not connect and program the nrf52832 chip of the development board, but I have been able to connect to my custom board, which is weird and I suspect that something is wrong with the development kit.

What I can do ? Any idea about debugging that ? Here I leave the screenshot of j-link

I have followed the tutorial of the following link without success neither.

Hi,

From the screenshot it seems like you try to use JTAG. This will not work, as the nRF5 devices only support SWD. Additionally, you might want to consider using nrfjprog instead for development, as that is more user friendly (but still a command line tool). That is part of the nRF5x-Command-Line-Tools distribution.
