#Log Level Setting Instructions

• Log level:

  The logs on the ARM side in the DSP module are mainly divided into 7 levels:

  The log level can be set to 0, 1, 2, 3, 4, 5, 6, corresponding to Verbose, Debug, Info, Warning, Error, Critical, Never, and the default is Warning.

  The logs on the DSP side in the DSP module are mainly divided into 5 levels:

  The log level can be set to 1, 2, 3, 4, 5, corresponding to Debug, Info, Warning, Error, Always, and the default is Warning.

• Log level setting rules:

  • If the log level >= the set level, the log can be printed, otherwise it will be blocked.
  • The lower the set log level, the more information will be printed. For example: if the log level is set to 3, which is the Warning level, logs of levels 3, 4, and 5 can all be printed. The default log level of the VP module is the Warning level, which means that the following log levels can be printed: Warning, Error, and Critical.
