Thanks for your support! I can see printk() log messages from nRF5340 NET core after adding the following configuration to prj.conf.

CONFIG_CONSOLE=n
CONFIG_SERIAL=n
CONFIG_UART_CONSOLE=n
# logging
CONFIG_LOG=y
CONFIG_LOG_PRINTK=y
CONFIG_USE_SEGGER_RTT=y
CONFIG_LOG_BACKEND_RTT=y

I have reverted main.c and prj.conf. But bus fault still occurred. 6521.hci_rpmsg.zip is zip file of hci_rpmsg folder I use. And west_forall_git_status_2.txt is result of west forall -c "git status" command after reverted main.c and prj.conf. Which version of Ncs do you use?

Yes, I suggest you revert all changes, also the changes you made in samples/bluetooth/hci_rpmsg/src/main.c.

I have added the configuration for logging in D:\ncs\v2.3.0\zephyr\samples\bluetooth\hci_rpmsg\prj.conf. Should I remove these configuration?

I see you've made quite a few changes, but the modifications you made to the hci_rpmsg are probably the most relevant.

Can you check what's changed in this file:

modified: samples/bluetooth/hci_rpmsg/prj.conf

Please refer to west_forall_git_status.txt for result of the following command.

west forall -c "git status"

I don't understand why you get this MPU fault when you build the same project as I did. I did not get this error.

Could you run the command below to see if you have any modified files in the SDK tree?

$ west forall -c "git status"

Procedure to reproduce this issue is as follows.

1. cd D:\ncs\v2.3.0\nrf\samples\peripheral_lbs_rtt

2. west build -b nrf5340dk_nrf5340_cpuapp

3. west flash --recover

4. Launching RTT Viewer and rebooting nRF5340 board.

5. RTT Viewer shows "BUS FAULT".

Please try the sample attached below and let me know if you get the same result. Only change I made was to add the child_image->hci_rpmsg config overlay.

I have added the following configuration in prj.conf file. But I still can't see any debug messages shown on RTT Viewer.

# logging
CONFIG_LOG=y
CONFIG_LOG_MODE_IMMEDIATE=n
CONFIG_USE_SEGGER_RTT=y

Hi,

Have you enabled the logger module and RTT backend? It is not enabled by default in the hci_rpmsg sample.

Best regards,

Vidar
