HSE is not working on STM32F411E-Discovery

Duc_Tran
Associate II

I’ve just started learning STM32 and I’m currently using the STM32F411E-Discovery board. I loaded the default code provided by the Board Selector in STM32CubeIDE and was trying to get a simple LED blink working. It works fine when using the internal HSI clock, but it doesn’t seem to work when I switch to the external HSE clock. The only different is:
HSI:

RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI;
RCC_OscInitStruct.HSIState = RCC_HSI_ON;
RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;
RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSI;
RCC_OscInitStruct.PLL.PLLM = 16;
RCC_OscInitStruct.PLL.PLLN = 336;
RCC_OscInitStruct.PLL.PLLP = RCC_PLLP_DIV4;
RCC_OscInitStruct.PLL.PLLQ = 7;


HSE:

RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE;
RCC_OscInitStruct.HSEState = RCC_HSE_ON;
RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;
RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE;
RCC_OscInitStruct.PLL.PLLM = 8;
RCC_OscInitStruct.PLL.PLLN = 336;
RCC_OscInitStruct.PLL.PLLP = RCC_PLLP_DIV4;
RCC_OscInitStruct.PLL.PLLQ = 7;

What do you mean by, "doesn’t seem to work"? Please describe the symptoms you see.

Have you used the debugger to see what's happening?

 

Does that board have a crystal for HSE, or is it clocked  from the ST-Link?

Details should be in the User Manual ...

 

I've edited you post to apply the proper source code formatting - please see How to insert source code for future reference.

See also: How to write your question to maximize your chances to find a solution.

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

There are 4 LEDs connected to PD12,13,14,15 in STM32F411E-Discovery board, i tried this with HSI, work completely fine. However, when i use HSE it not turning the LEDs on neither blinking, there is no error in debugger. I read the manual and STM32F411E-Discovery does have an 8Mhz crystal connected to PH0 of the STM32F411VE

    HAL_GPIO_WritePin(GPIOD, LD3_Pin, GPIO_PIN_SET); // Set LD3 pin high
    HAL_GPIO_WritePin(GPIOD, LD4_Pin, GPIO_PIN_SET); // Set LD4 pin high
    HAL_GPIO_WritePin(GPIOD, LD5_Pin, GPIO_PIN_SET); // Set LD5 pin high
    HAL_GPIO_WritePin(GPIOD, LD6_Pin, GPIO_PIN_SET); // Set LD6 pin high
    HAL_Delay(500); // Delay 
    HAL_GPIO_WritePin(GPIOD, LD4_Pin, GPIO_PIN_RESET); // Set LD4 pin low
    HAL_GPIO_WritePin(GPIOD, LD3_Pin, GPIO_PIN_RESET); // Set LD3 pin low
    HAL_GPIO_WritePin(GPIOD, LD6_Pin, GPIO_PIN_RESET); // Set LD4 pin low
    HAL_GPIO_WritePin(GPIOD, LD5_Pin, GPIO_PIN_RESET); // Set LD5 pin low
    HAL_Delay(500); // Delay 

  

Hello @Duc_Tran and welcome to the ST community,

Make sure all these components in the RED recatngle are available on your board:

If you are using CubeMx or CubeIDE could you please attach your ico file?

So the code correctly steps through the sequence of writes to the pins, but the LEDs don't go on/off ?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

If the DISCO board is taking it's HSE clock from the ST-LINK PBA/MCO pin then HSE needs to be configured in BYPASS mode on the F4.

Check what's failing. Are you getting a TIMEOUT on the initialization?

Tips, Buy me a coffee, or three.. PayPal Venmo
Up vote any posts that you find helpful, it shows what's working..

Yes, no errors or anything.

i was trying to fix it but still not working, the board does have all the components, here is the full code and
