nRF53 BLE in cpunet

[AntonD]

I am attempting to write my own nRF5340 cpunet bootloader using nRF Connect.

This code is likely to be in a medical device; so, it is crtiical to be able to recover from faults, particularly exclusively via BLE. In the case that the application (in cpuapp) is faulty, I want to be able to recover entirely from the cpunet bootloader. The cpuapp BLE behaviour doesn't compile, which isn't a big surprise as it mostly is using SoC communications from the cpuapp to the cpunet.

The questions is, is it possible to access the BLE behaviour exclusively from the cpunet core?

This worked. I just wanted to add that I needed to run/debug an application on the cpuapp core to allow debugging (as said on numerous other boards that I won't reference here).

VS Code is able to debug both cpuapp and cpunet with BLE behaviour now. Thanks!
