Can not set "nBOOT_SEL" bit in STM32L011F4 MCU.

Hello, everybody.

I am developing one small application, using STM32L011F4 MCU. As I realised from datasheet, there are two ways to boot from flash memory:

1)Connect PB9-BOOT0 pin to ground;

2)Set nBOOT_SEL bit and use nBOOT0 bit instead of BOOT0 pin.

Also, datasheet says that nBOOT_SEL bit available only for Category 1 devices.

Again, according to datasheet, STM32L011F4 is category 1 device:

The problem is that I can not program nBOOT_SEL bit using ST-LINK UTILITY, it is shown in gray color and I can not check/uncheck it.

What could be the problem?

Try the STM32 Cube Programmer, it is the software they have migrated too.
