I have nerver use a RTOS in a project, and the FreeRTOS is my first attempt. I want to use it on MSP430F5438 platform, but i do not know how to port it. Does someone had done this work? I need a help.

Just start with a demo and port that use the same architecture, then change the linker script for your particular part. Take care with the MSP430 and there are two MSP430 variants. You might try here too

Thanks for you suggestions. I have downloaded the demo at, and send a mail to Jhon, but no response.
MSP430F5xx’s architecture have a little differences from previous versions. So the current 430 port is little help.

I have a port.c and portmacro.h for the MSP430X 20-bit mode, using the TI CCE 3 compiler.  I did some testing on it using the TI 'F5438 eval board but no guarantees it is reliable.  You are welcome to the code as a starting point if interested.

FYI it isn’t GCC compatible.  The stack parameters for calls is different in CCE.  I’m not aware of a GCC that fully supports 20-bit addressing for the MSP430X.

I don’t have a place to make the code available to the web, but if someone volunteers to host it I can send it by email attachment.

I replied to your e-mail - you forgot something:

IAR Project for 430X - Password Request - **Plus Brief Explanation Of Project** -

You did not include the brief explanation of your project in your request.
Do you want the IAR & CCE (CCS) password(s)?
