RTT Viewer doesn't show any debug messages of hci_rpmsg from nRF5340 NET core

snowuyl

Procedure to reproduce this issue.
1. cd D:\ncs\v2.3.0\zephyr\samples\bluetooth\hci_rpmsg
2. west build -b nrf5340dk_nrf5340_cpunet
3. west flash
4. Lauching RTT Viewer and selecting NRF5340_XXAA_NET target device
5. RTT Viewer doesn't show any debug messages

The following are log messages of RTT Viewer. Why does it shows "Security extension: not implemented"?

    Hi,

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

    Best regards,

    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
    CONFIG_RTT_CONSOLE=y
    CONFIG_LOG_BACKEND_RTT=y
    CONFIG_UART_CONSOLE=n
    CONFIG_PRINTK=y

    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"

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

    west forall -c "git status"

    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

    ?
