Hi, we are developping a medical device that receives an audio stream from a smartphone. We have a custom board connected to a different DSP than the one in the nrf5340_audio_DK, so for us does not make sense to use the provided example files (on the contrary is creating quite confusion for us).
With a standard nrf5340_DK board, and a modified example unicast server we are getting error "*** Booting nRF Connect SDK v2.9.1-60d0d6c8d42d ***
*** Using Zephyr OS v3.7.99-ca954a6216c9 ***

We have created a folder \sysbuild\ and added a conf file for the CPUNET as explained on this same forum "/sysbuild/ipc_radio/overlay-bt_hci_ipc.conf" :
this is our prj.conf:
thanks in advance for the support.
