“Wouldn’t it be C O O L to have a Linux prompt on the STM32F103C8T6. Not likely, however, Nuttx on the STM32F103C8T6 is about as close as you will get.
Nuttx is a RTOS which runs on a wide range of microcontrollers including the STM32F103C8T6.
To compile Nuttx for the STM32F103C8T6, a development environment needs set up with the right tools. My development OS of choice is a Linux distribution called Fedora (Fedora 29 is the current version at the time of this post).”
