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.
