CMSIS Version 5

This directory contains a ported version of the upstream repository for CMSIS_5 as well as Mbed specific RTX configuration and RTOS boot source files.

The upstream source code is imported using the Python script located at tools/importer/importer.py when passed the tools/importer/cmsis_importer.json configuration file. For more information on the importer script please read tools/importer/README.md.

The directory is organised as follows:

+--cmsis
|   +-- README.md                           # The present mardown file
|   +-- device/

Two Mbed libraries live within this directory:

  • rtos from device/rtos
  • cmsis-cmsis5-rtos2 from CMSIS_5/CMSIS/RTOS2
