We just release OS-9 6.0 and one of the biggest changes is support for ARMv7-A series. We have BSP's for Cortex A5/A7/A8/A9 Unfortunately the
STM part you asked about is a ARM -M series. The 512K flash and 96KB of
sram is a bit to small for OS-9 on ARM. We do not currently support the
Thumb or Thumb2 instruction set. At this time we are looking at the
direction of OS-9 moving forward. This part might be a bit on the small
side for an RTOS unless you strip out some functionality.

I loved OS-9 on the coco with level 2, it was easy to learn and use, but now 20 years later I wonder if it is available for the ARM STM32f401RET6 which comes with 512k flash and 64k sram., my board also has an sd card available.
