Hands-On RTOS with Microcontrollers

Hardware bring-up

Hardware bring-up is the act of first powering on a custom-designed piece of hardware and performing some level of verification on it. Custom hardware will often have many differences compared to a development/evaluation board (it is custom, after all!). One area that may differ is clock hardware. STM32 clock trees are fairly complex—a single clock source feeds many different subsystems. The clock frequencies get modified along the way by multipliers and dividers. CubeMX contains a graphical wizard to help properly configure the STM32 clock tree and generate initialization code to get the chip up and running quickly.

Early firmware effort will also be required to verify the hardware is operational. It is always a good idea ...
