Manually implementation of FreeRTOS on FRDM-KL25Z

Hello,

I would like to implement FreeRTOS on the board FRDM-KL25Z. However, without using the RTOS from the SDK or the processor Expert. I would like to create a new project using SDK so I do not have to worry about the drivers anymore. Then the latest version, which is available for download at freertos.org, can be entered manually into the project.

I have so far proceeded as follows:

Create a new project using SDK and the included FreeRTOS (so I have the folder structure in mind)
Create new project with SDK without FreeRTOS but with the drivers for the board.
Replication of the folder structure from point 1
Insert the FreeRTOS files into the corresponding folders

However, I get a lot of error messages like Missing libraries. If I fix an error, the next one arises. Is there an instruction, which describes the best approach? Or is my approach completely wrong?

Hi Thomas,

your approach and steps are correct, and it works that way if you really want 'plain' FreeRTOS 9.0.0.

What you want is what I have on GitHub (mcuoneclipse/Examples/KDS/FRDM-KL27Z/FRDM-KL27Z_SDKv2_FreeRTOS.org at master · GitHub).

I'm not sure how familiar you are with FreeRTOS, but I think you might have used the wrong files or not updated the compiler include path settings. Have a look at above project and readme file, and hopefully this helps.

Erich
