While ((PWR->D3CR & (PWR_D3CR_VOSRDY)) != PWR_D3CR_VOSRDY) _HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE1) * Configure the main internal regulator output voltage */ RCC_PeriphCLKInitTypeDef PeriphClkInitStruct So, in variant.cpp pertaining to my board I changed the old function WEAK void SystemClock_Config(void) we connect a digital clock signal instead of a crystal. The clock had to be configured to use HSE (High Speed External) oscillator set to bypass mode – i.e.
This clock is 8 MHz and is derived from a crystal.
Instead, I used STM32CubeMX and knowledge from this course (I highly recommend courses by this author) to configure the MCU to use external clock provided by the onboard STLink programmer. I could’ve tried to calibrate the oscillator, but I didn’t bother. The result was that the UART was 6% too slow. Even if I use STM32CubeProgrammer it can only connect with target if Reset mode is set to Hardware reset.It turns this Nucleo board version was configured in stm32duino to use I think the worst clock option, that is CSI, which is an internal 4 MHz RC oscillator. There is definitly something wrong with reset method.

It looks like theere is a problem with resetting target MCU. It has ST-Link v3 onboard and FW is up to date. But there is a problem with uploading/debuging.
