Hi kukenov.andrei,

The issue exists unfortunately but it will be fixed in next version of STM32 ST-LINK Utility.To configure option bytes you can either call the command -OB, or you can also program a hex file with the option bytes config.In your case to program Data0, create a hex file of one byte length with the value Data0 to program address 0x1FFFF804.-Syrine –
