Configuring Platform

The platform configurations allow for customization of platform-level OS options. These options include error handling properties and serial communication configuration settings for STDIO. They affect system level printf calls, not Serial objects, with the exception of default-serial-baud-rate.

This is the complete list of platform configuration parameters. To view all configuration parameters, run the --config -v command. Please see the configuration system documentation for details on how you may use or override these settings.

Configuration parameters
------------------------
Name: platform.all-stats-enabled
    Description: Set to 1 to enable all platform stats. When enabled the functions mbed_stats_*_get returns non-zero data. See mbed_stats.h for more information
