Dear FreeRTOS Forum: I am using IAR Workbench and got the FreeRTOS demo “msp430_IAR” to build. However, this demo’s architecture is for SoftBaugh’s ES449 prototyping board. I followed the instructions on p. 161 (steps 1 – 6) of the FreeRTOS tutorial book for adapting one of the supplied demo projects. I removed all demo source files except heap_1.c and main.c and got the project to compile. However, I want to port to the MSP430FG4618 (instead ES449). So I changed the header file in FreeRTOSConfig.h from “#include <msp430x44x.h>” to “#include <msp430xG46x.h>”. Now the project will not compile. How can I get project to work on FG4618? Here are the error messages: Building configuration: RTOSDemo – Debug

The MSP430F449 uses an MSP430 core.  The MSP430FG4618 uses an MSP430X core.  The FreeRTOS download contains 2 demos for the MSP430X in the FreeRTOS/Demo/MSP430X_MSP430F5438_CCS4 and FreeRTOS/Demo/MSP430X_MSP430F5438_IAR directories respectively.  Each demo uses 3 different memory models.  There is a lot of code behind it.  The ports for these demos are found in the FreeRTOS/Source/portable/CCS4/MSP430X and FreeRTOS/Source/portable/IAR/MSP430X directories respectively. I suggest you look at one of these demos as a starting point. Regards.

So I changed the header file in FreeRTOSConfig.h from “#include <msp430x44x.h>” to “#include <msp430xG46x.h>”.
I think this might be the first error: check if it the right to get included  <msp430xG46x.h>” then check any error above, and try to edit the right folder/file which gets an error. I’ll send you more notes later. Regards,
Enri.

Hi Enrid: Thank you for your help. If you are able to send me your code, that would be great. I am using IAR Workbench IDE, but as you said, I can make the necessary changes. The reason for needing this port is that I am trying to adapt FreeRTOS for use on the MSP430fg4618/MSP430f2013 experimenter’s board. It’s not for a specific project at this time. However, I want to be able to add FreeRTOS experience to my resume, as some companies I’m looking at are interested in this. Thank you again. Regards,
Anne
