X-CUBE-ST67W61 for bare metal and/or ThreadX?

Southbranch · ‎2025-11-24

Hi,

We have the X-NUCLEO-67W61M1 (for ST67W) attached to a custom STM32U5-board. Disappointingly we just found out the whole architecture of X-CUBE-ST67W61 seems to rely on FreeRTOS while our app architecture is based on ThreadX…

A light weight bare metal approach would be highly appreciated when starting up simple testing with e.g AT-commands! Then we want to use ThreadX for an HTTP server among other things.

Any recommendations on potential work arounds using the X-CUBE-ST67W61 without switching to FreeRTOS?

Thanks in advance

Well, ST's stated strategy is to use FreeRTOS:

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Many thanks, I will check this out!

Ohh.. thanks I haven't seen that but can't really believe it, will be a mess for our project...

Seems Free RTOS also will be mixed with USBX and FileX..
