 To validate the bare metal target configuration, execute the Mbed OS Greentea test suite with the bare metal profile. This profile causes Greentea to skip a subset of the tests, either because the underlying functionality has not been ported to bare metal or because some tests require RTOS features (for examples, more complex tests based on multi-threading).

+Follow steps in [Running Greentea tests for bare metal profile](baremetal_usage.md#running-greantea-tests-for-bare-metal-profile). All tests should pass (or be automatically skipped).
 
 Further optimisations for targets with small flash memories:
 - Append `--profile release` to the command above. Use of the release profile helps keep some tests within the size limit.
