Question

STM32F030F4P6 option byte programming

Can recognize the chip, but can not burn and read the flash problem. In this case, is the chip broken or the chip locked?

There is also a case that the chip can be identified as burning, but it cannot run the normal working program

Is this a genuine programmer? The serial number "123456" is suspect.

Can you connect over SWD?
