Hello @Tarun , 

If you are unable to connect to your Nucleo STM32G0B1RE board after enabling the Boot0 option byte in Flash Security, it is likely that the board is stuck in bootloader mode. To resolve this issue, you can try the following steps:

1. Disconnect the board from your computer.
2. Short the BOOT0 pin to GND using a jumper wire or a switch.
3. Reconnect the board to your computer and try to connect to it.
4. If you are able to connect to the board, you can clear the option byte by erasing the chip or using your programming software to clear the option byte.
5. Once the option byte is cleared, you can remove the jumper wire or switch from the BOOT0 pin and try to connect to the board again.

Hi Foued,

I shorted pin 7 and 8 in the image but still same error seen on the Cubeprogrammer.  Is am I missing anything?
