None of the apps in nrf connect works with a nrf5340 board.

Bluetooth low energy, Direct Test mode nor RSSI Viewer is working with my nRF5340DK board. For instance with RSSI Viewer it says "Error while setting up device XXXXXXXXXXXX: No firmware defined for selected device" but if i connect to the serial port i can see that the shell is running and i can run the commands given here. With the DTM app it says "No firmware defined for selected device Please make sure the device has been programmed with a supported firmware"

Hi,

RSSI only support nRF52-series, this is shown in the About section if you open the app in nRF Connect.

Regarding DTM you are looking at the wrong project, you should look at the DTM project here:
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/bluetooth/direct_test_mode/README.html#building-and-running

Hope that helps,

That is the one I'm trying to use, but for some reason i cant get it to work

west build -p auto -b nrf5340dk_nrf5340_cpunet nrf/samples/bluetooth/direct_test_mode/ && west flash

What do you do to the application core?

As you can see from above, I'm flashing it with the command "west flash". Does anything else needs to be done prior to the flashing?

Yes, please see "Note" in the link I shared earlier.
