When first programming a New STM32L431KC, it does not program or run unless mass erase is performed first.I use IAR and STLINK/V2From IAR, I try:a) Download program - uC does not run, even after resetb) Start debugging session - Does not execute code...

I have been using printf() to output to UART for many years on a STM32L052All these projects still compile and printf() to UART, no problem.I started a NEW project with CubeMX, but now printf() does NOT print to UART.I use the same int fputc(int ch, ...

MOOC FreeRTOS on STM32 v2 - 11a Context switching at 14:00, what is the WaveFroms program shown?Is it a Scope output, or some STM app,.Any help appreciated

How can I view / display table of variables in STM32CubeMonitor, as in STM Studio?Any help appreciated

Thanks, and yes that works.The F051, L051, L052 and others does not do that.The only difference on the boards is the on the L431 I use a 32KHz resonator.Perhaps that is it.

Paul,I am still struggling to make it work.If I put breakpoints, and step over, the app does NOT crash.printf() still has NO output, but is does not crash, and the rest of the app continues.If I remove the breakpoints, the app crashes, and I cannot f...

TDK,The app actually crashes at my printf("\r\nmyString\r\n");Regards

TDK,YES - HAL_UART_Transmit(&huart1, (uint8_t *)message, string_lenght, 100);NO - Does NOT break at fputc

Re: Is there a FreeRTOS demo program, using STM32CubeMX to set up, for: STM3240G-EVAL - EVAL with STM32F407IG MCU or STM32L476G-EVAL with STM32L476ZGT6 or STM32F429IDISCOVERY with STM32F429ZIT6 Any help appreciated
