"WebSep 24, 2024 · Tasks that call printf() probably need more than 64 words of stack. You are probably multithreading calls to the UART driver (from the ST HAL?) and the driver likely doesn’t support that. You may need to use a mutex or change the design to share the UART output. Remember that FreeRTOS allocates each task’s TCB and stack from the heap. " - Freertos printf uart
