According to ST AN2867 Oscillator design guide for STM32, the oscillator circuit requires a Rext resistor
There are minimal boards with stm32f030f4p6 on ebay, aliexpress... It looks that rext is missing on the schematics. It only have a crystal and 2 capacitors Do you think the board can run on HSE anyway ?
Here is the schematics http://www.uctronics.com/download/U3808-1.jpg
