Logger

Logger class is used for sending log messages coming from LOG macros:

LOG_PRINTF
LOG_TRACE
LOG_DEBUG
LOG_INFO
LOG_WARN
LOG_ERROR
LOG_FATAL
LOG_CUSTOM

to a proper device (SEGGER_RTT, console output, SYSTEMVIEW) and at the same time to put them to a circular buffer.

Circular buffer has a limited size which sometimes results in losing some logs.

In such a case, proper lost message info is added to msg received from the buffer.

Dumping to a file

Logs from Circular buffer are dumped to a file named MuditaOS.log every 10 sec by EventManagerCommon timer.

Current max log file size is 50 MB (after reaching this size no more logs are dumped).

Logs can be accessed using mount_user_lfs_partition.py script from tools directory. Additionally, test/get_os_log.py script allows getting a log file from a running phone.
