Freescale MQX Release Notes

Freescale Semiconductor

3.2.1 MQX RTOS Directory Structure

The RTOS files are located in the mqx subdirectory of the Freescale MQX™ RTOS installation. The

directory structure is briefly described in the picture below.

3.3 MQX MFS

This release Freescale MQX™ RTOS includes the MFS File System libraries. The MFS is based on

the version 2.20 released by ARC.

The major MFS modifications as compared to the ARC release:

‐ The compile-time configuration of the MFS is now accomplished by editing the

.../config/<board>/user_config.h file.

‐ MFS was significantly optimized for devices with limited RAM resources. In particular, MFS

now performs sector caching, not cluster caching. This generally results in better

performance with a lower RAM footprint.
