READ_BIT(RCC->CR, RCC_CR_HSERDY) fails with a HAL_TIMEOUT when running blinky in debug.

[lwatcdr]

While in debug I get and error in this line of code. I do not get an error when running code not in debug.

/* Wait till HSE is ready */
while (READ_BIT(RCC->CR, RCC_CR_HSERDY) == 0U)
{
if ((HAL_GetTick() - tickstart) > HSE_TIMEOUT_VALUE)
{
return HAL_TIMEOUT;
}
}

I don't know. The important thing is to get the code correct. You should verify on your board this is actually the case.

I am encountering the same mentioned problem. Could you please share the solution or any guidance on how to resolve it?

Facing the same problem here. 

I've tried setting the input frequency to 16 as suggested, but that didn't help.

Any other solutions?

PS: I've downloaded and installed the latest versions of STM32CubeIDE and STM32CubeMX today.

Here are some detail pictures of my board. I think these are the correct default settings. (I got the board from a customer. I don't think they changed anything to the jumpers.)

Never mind. Found the fix. 

The setting for HSE must be set to 'Crystel/Ceramic Resonator', just like with the LSE. 

Now I can debug my project.
