The only way to make this simple blinky to work was to had the 2 lines where I put the result of HAL_GetTick() in a random char array that I don't even use. If I just toggle pin and delay, the code seems to crash on the HAL_Delay. I must precise that my blinky and my Fre...

SysTick in an STM32 will trigger an interrupt every 1 ms. If we’re using the STM32 HAL, by default, SysTick will be used for things like HAL_Delay() and HAL_GetTick(). As a result, the STM32 HAL framework gives SysTick a very high priority. However, FreeRTOS needs...
Reimplementing HAL_GetTick as in Blinky from Keil.STM32H7xx_DFP also work after the kernel is started. As I said, I think that such behavior is a design choice to keep the kernel state machine consistent until the kernel is started. FreeRTOS maintains the ports but I don't think this ...
