Hello @pGami.1 ,
Did you finally manage to resolve your issue ?
Make sure to follow the I2C configuration for accessing the bootloader as described in AN2606
The STM32G03xxx bootloader is activated by applying Pattern 11 (described in Table 2: Bootloader activation patterns) and note that STM32G030x don’t have BOOT_LOCK(bit), so consider that when using pattern 11.
