1. Please help me resolve the log error that occurs with CONFIG_LOG_DEFAULT_LEVEL=4

2. I created a very simple example of log printing and it worked fine when I set CONFIG_LOG_DEFAULT_LEVEL=3.

3. When I set CONFIG_LOG_DEFAULT_LEVEL=4, the printed log shows the error message as follows:

4. The code is as follows:

    Hi,

    I am a bit confused regarding what error you see. When raising the log level you will get more log messages, and none of the messages looks like error messages. To me it looks like no errors? Please point out the specific error, and we may have a look.

    If the error is the squares that you see, then this is typically special characters or special character combinations for changing text color on certain terminals. You can turn off color codes through CONFIG_LOG_BACKEND_SHOW_COLOR=n, and/or CONFIG_LOG_INFO_COLOR_GREEN=n (in your prj.conf.)

    Regards,
    Terje

    Hi,

    One potential issue is sometimes logging may take too much time, preventing time critical operations. That may be what is happening here, especially if you are not using deferred logging mode. You can turn on deferred logging through CONFIG_LOG_MODE_DEFERRED=y.

    Regards,
    Terje

    Hi test,

    1. set  CONFIG_LOG_MODE_DEFERRED=y is ok.

    2.But how do I configure prj.conf to turn off the mpu part of the log

    Thank you for all your assistance.
    Kind regards,
    Peter.Min

    Hi,

    You can set MPU log level through the CONFIG_MPU_LOG_LEVEL_* options, where * is one of DBG, DEFAULT, ERR, INF, OFF or WRN. So for instance CONFIG_MPU_LOG_LEVEL_OFF=y should turn off all logging for MPU.

    Regards,
    Terje

    Hi tesc,

    Your suggestion is very good

    log printing is ok after the following modification

    CONFIG_MPU_LOG_LEVEL_OFF=y
    #CONFIG_MPU_LOG_LEVEL_ERR=y
    #CONFIG_MPU_LOG_LEVEL_WRN=y
    #CONFIG_MPU_LOG_LEVEL_INF=y
    #CONFIG_MPU_LOG_LEVEL_DBG=y

    CONFIG_KERNEL_LOG_LEVEL_OFF=y
    #CONFIG_KERNEL_LOG_LEVEL_ERR=y
    #CONFIG_KERNEL_LOG_LEVEL_WRN=y
    #CONFIG_KERNEL_LOG_LEVEL_INF=y
    #CONFIG_KERNEL_LOG_LEVEL_DBG=y
    Thank you for all your assistance.
    Kind regards,
    Peter.Min
