Describe the bug
Tested with blink sketch, custom board (8mhz crystal + CH340). The chip works with stm32duino 1.9.0 using "STM32F030F4 Demo Board", but when tried with any version past 1.9.0, it uploads the sketch without issues but it doesn't execute properly ie led is not blinking. Other sketches also don't work.

To Reproduce

1. Select STM32F030F4 board (8mhz HSE)
2. Upload basic blink sketch to STM32F030F4P6
3. No blinking
