Hi,

I’m quite new in freeRTOS and looking port for Open4/EvoPrimer. I’ve found ports for old primer1/primer2 but not for current hardware. Does anyone can help me?

Best regards

Piotr

The same FreeRTOS Cortex-M code works on all Cortex-M chips so there is no porting to do as such. All you will have to do is add the FreeRTOS files to the project. Use the FreeRTOS/Source/[compiler]/ARM\_CM3 files for Cortex-M3 or Cortex-M4 without an FPU, and FreeRTOS/Source/[compiler]/ARM\_CM4F for Cortex-M4 with an FPU.
