Issue: Failed to use external 8MHz xtal on Nucleo-F030R8
The code in SetSysClock() should auto-select clock source. But it didn't work when I tried to use 8MHz crystal.
There is a systick timer being used as timeout counter. When timeout happens in RCC configuration, the program will move on to use 8MHz crystal. But After setting the HSE, the return value of HAL_GetTick() never increases.
Then program hangs!
That may because the code of mbed reconfigured the HAL tick using a standard timer instead of systick.
