Hi Peko,

If all you need is to change the option bytes on your STM32G070 board, I suggest you use the STM32CubeProgrammer software available on ST web site here .

It offers a variety of features including the option programming via a user friendly interface and easy to manipulate.

I hope this help!

Hi,

For better explanation I did attach an screenshot of the CubeProgrammer software showing the option bytes you need to modify.

All you need is to uncheck the needed option and press "Apply"

The connection of the board via the CubeProgrammer software is through ST-Link probe.
