STM32F030T8 code don't launch

[Jjponvv]

I have an Arduino STM32F030T8C6 board. For develop on it I use USART. When I create code where LED is blinking and push it to board nothing happens. I tried to enable or disable BOOT0 but it doesn't work. On this board PA9 and PA10 on A9 and A10. It board also have micro-usb but i can't see it like DFU device. I don't know what to do. This is my settings:
