MDK MIDDLEWARE: Can Middleware work standalone without using RTOS?

Information in this knowledgebase article applies to:

• MDK v5.x
• Middleware Pack

QUESTION

I want to use Middleware library, such as Network Component, USB Component, etc., in a standalone mode without using any RTOS.

Is it possible?

ANSWER

CMSIS-RTOS RTX is used in all components of the Middleware library pack, such as networking, USB or filesystem etc., for task scheduling. The Middleware library requires a CMSIS-compliant RTOS. An application without an RTOS is not supported. The library is validated with CMSIS-RTOS RTX.

Both CMSIS-RTOS v1 (RTXv4.x) and CMSIS-RTOS v2 (RTXv5.x or later) are supported to be used with Middleware library.

The earlier RL-ARM library, such as RL-TCPNet, RL-USB etc. can work with RL-RTX or work in a standalone mode (without using RL-RTX). However, note that RL-ARM is now only under maintenance without further development. The latest RL-ARM library can be found in the latest legacy support pack.

MORE INFORMATION

• Refer to the MDK Middleware.
• Refer to RL-ARM User's Guide in the RL-ARM User's Guide (MDK v4).
• Refer to the MDK v4 Legacy Support.
• Refer to the CMSIS standard.
