Build AZRTOS with CMSIS-RTOS v2 or use ThreadX calls directly

Question

Hi,

I want to know if it is best practice to mix both CMSIS_OS2 API threads and native THreadX threads in a project or should I just port old code over to native THreadX threads instead.

I'm building an embedded device using AZRTOS and STM32 Microcontroller platform. I have to port STM's cellular modem FW package to run in my application. That package is based on FREE RTOS and CMSIS_OS V1 api. After porting that functionality I will need to then use NETXDUO to run the PPP interface plus build out the application logic.

My options are

1. Converting the cellular modem interface to CMSIS_OS2 API and then use ThreadX native API for any new threads
2. Convert the cellular modem interface directly to ThreadX native API

Is option 1 best practice or should I just convert all the FreeRTOS calls to ThreadX?

Thanks

Answer 1

I would suggest converting directly to native ThreadX.

You do have a third option: use our FreeRTOS layer https://github.com/azure-rtos/threadx/tree/master/utility/rtos_compatibility_layers/FreeRTOS
