HAL_TIMEOUT error from HAL_RCC_OscConfig()

Hi,

my app works fine when I use the internal clock but if I switch to external clock I obtain HAL_TIMEOUT from function HAL_RCC_OscConfig().
The external clock board schematic is:screen_3.jpg
Clock configuration is:screen_1.jpgscreen_2.jpg

The main.c is:

I don't understand what is going on, please anybody can help ?

    @Beppe101 You showed in your schematics that you are using a crystal connected to OSC_IN and OSC_OUT, right?

    Then you configure the HSE to BYPASS Clock Source, which does not expect a crystal, but an external oscillator connected to OSC_IN.

    So if you want to work with a crystal at OSC_IN/OSC_OUT, you have to set the HSE option to Crystal/Ceramic Resonator, as @Sarra.S already wrote.

    Hello @Beppe101

    This is likely caused by misconfiguring the HSE clock, if HSE is selected as the clock source in the clock configuration, under the Pinout & Configuration tab select crystal/ceramic Resonator in the high-speed clock (HSE).

    if you're supplying your clock to the MCU's RCC_OSC_IN pin, then select the BYPASS Clock Source option.

    Hi Sarra,

    thanks for your answer, as shown in picture above I selected BYPASS_Clock_Source but this does not work as expected.

    What could be the reason for issue ?

    Problem is solved by answers above, but just so you know what's going on inside the STM32:

    - BYPASS mode assumes that you feed the clock input from an active oscillator to only one pin (attention, must be the one called Pxy_OSC_IN), usually having a push-pull output and delivering (something close to a) square wave with a voltage swing from 0V to VCC.

    - the other mode called Crystal/Ceramic Resonator assumes you connect a passive crystal / quartz with the caps - as you did - which uses both pins, because internally the STM32 has its own oscillator circuit, exiting and working with the low power and small amplitude crystal.
