Seems to work as intended here. Adding my board file.

devzone.nordicsemi.com/.../4643.custom_5F00_nrf5340.zip

I did the guide described here:
https://devzone.nordicsemi.com/nordic/nrf-connect-sdk-guides/b/getting-started/posts/nrf-connect-sdk-tutorial---part-3-ncs-v1-4-0#h113sk0f71cly1ckwgkkxioblcbcsge6

This is ncs v1.7, and using a nRF5340 DK that fulfill:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_nrf5340.html

I also executed first:

nrfjprog --recover --coprocessor CP_NETWORK
nrfjprog --recover

Best regards,
Kenneth

thanks for the reply. I am using the nRF5340DK for my tests. if I build with the nRF5340DK_NRF5340_CPUAPP i works fine. If I build for the custom board (which is just a copy of the nRF5340DK boards directory from Zephyr) it fails. It looks like it is not defining the network core or the HCI_RPMSG correctly

If bt_enable() never return when using the DK files, then I would instead look at hardware changes between the DK and custom board. For instance does the custom board have external 32kHz crystal?

the Tutorial is for a nRF52 board and is helpfull, but there appears to have an issue with the network core of the nRF5340.

I copied all the board files from the 5340 (secure version) into my custom board folder. Renamed the files to match the new board name. So now I have a custom board that should be identical to the zepher based 5340DK secure version.

If I use the custom board for either of the projects the outcome is the same, bt_enable() never returns. There are missing domain definitions for the network core in the custom board, I think that is the root cause of the failure. There is some other configuration file that is used when zephyr is built that is not in the board folder. I have looked though documentation and cannot find a list of the actual configuration files used when doing the first stage of the build

I suggest you follow this guide:
https://devzone.nordicsemi.com/nordic/nrf-connect-sdk-guides/b/getting-started/posts/nrf-connect-sdk-tutorial---part-3-ncs-v1-4-0#h11sk6ks1jkp1figkuq6gxw1m1rctdp0

The VSC create custom board for the nRF5340 I thin is very limited at the moment, so I recommend to instead use the nRF5340DK board files as suggested above as basis for your custom board. Then you for instance ensure that things like these are handled:
