I recommend anyone just starting with bare-metal assembly to get an STM32F0 board and write assembly programs for it. I'm just gonna plug my super small toy RTOS I wrote for Cortex-M0 a while ago.

CubeMX is the best config manager I've ever used, the clocking interface alone should be mandatory for all embedded companies.

I have still yet to really need an RTOS, even for BLE.
