Hi,
I got a nrf5340 pdk, and I download demo Peripheral_Heart_Rate into board, load peripheral_hr.hex into app_core and load hci_open_amp.hex into net_core. it running ok. but I erase app_core flash, compile zephyr/samples/bluetooth/beacon demo, and used tool with command 'west flash' program app_core flash, but it not work, Looks like bluetooth initialization failed, what should I do slove this problem. Thanks
