FreeRTOS ported version for stm32u545re microcontroller (Cortex-M33)
This repository provides a minimal and working FreeRTOS port for the STM32U545RE microcontroller based on the ARM Cortex-M33 core.
It is intended as a clean starting point for developers building low-power IoT and embedded applications on STM32U5 devices.
Example is simple switching between two tasks on serial monitor.
porting procedure:
1. modified systick handler to generate time slice with respect to cortex m33 processor.
2. modified pendSV handler to perform context switching between tasks with respect to cortex m33 processor.
3. modified supervisor call handler to determine which os service is requested to cortex m33 processor.
