I would to generate option byte file in hex format

[Vikas1]

@Exmple:

:020000041FFFDC

:01F800000007

:020000041FFFDC

:01F80200FF06

:020000041FFFDC

:01F80400FF04

:020000041FFFDC

:01F80600FF02

:020000041FFFDC

:01F80800FF00

:020000041FFFDC

:01F80A00FFFE

:020000041FFFDC

:01F80C00FFFC

:020000041FFFDC

:01F80E00FFFA

:00000001FF

I was able to do the same in F series with the help of STVP tool, but in G0 series it is not possible.

Which STM32G0xx part specifically

I think the G0 have the Option Bytes at 0x1FFF7800 rather than the 0x1FFFF800 range this HEX data shows for the F0 series, total 16-bytes

It might be possible to array similar records for the G0 series.

Typically an erase, and rewrite all type operation, right?

Cubeprogrammer supports this?

Not sure, not using G0 here, but Keil typically has a "Flash Algorithm" for the option byte memory when programming the devices.
