Hello @bbb,

Could you please provide further details : Which part number are you using ? Are you using a custom board ? Can you connect in CubeProgrammer standalone version ?

Thanks in advance,

Aziz

They make literally hundreds of "STM32", could you narrow this down a tad, and provide some context to your question.

Try jumpering / pulling BOOT0 HIGH, to VDD, will stop your broken code from running.
