nRF9160 Custom board debug issue

[Vincent44]

Hello DevZone

I am facing an issue debugging my custom board, that embeds an nRF9160. I use a JLink Base to debug the board.
I used to be able to debug with no problem, but it no longer works. Since, I am not sure why exactly (jlink updates ? VS Code ? SDK ? Toolchain ?), I started from scratch and created a dummy project, just for this troubleshoot.

I am using SDK and toolchain 2.4.2.

I created a new project, with a basic main that loop forever.
I created 2 build configurations

• One using the existing nrf9160dk_ns board.
• One using a custom board, selecting the SoC nRF9160 NON SECURE.
    I only added the following lines in prj.conf to get the compilation to succeed
      CONFIG_TRUSTED_EXECUTION_NONSECURE=y
      CONFIG_BUILD_WITH_TFM=y

In both cases, I can compile the firmware and flash my board. This means that both my JLink and PCB are working.
Trouble starts when I want to start a debug session ...

Using the build configuration of my custom board results in the following error.


If I select the build configuration with nrf9160dk_ns, I am able to launch a debug. However, this is not what I want, since this configuration contains the device tree corresponding to the DK.
