Device is under Read Out Protection?

[DBalz.1]

Hi all,

i'm tryng to connect to STM32F048T6 by STM32CubeProgrammer.

It is a virgin device, and it starts from System memory and i can see the device like STM32 Bootloader.

When i'm trying to connect using USB in the STM32CubeProgrammer a pop-up message appears reporting: "Deevice is under Read Out Protection, Do you want to disable it?"

I checked the RDP level and is set to AA, so level 0.

Do you have some ideas?

The voltage level are:

VDD = 1.8V

VDDA = 1.8V

VDDIO = 3.3V

I'm using HSI48

This is the CubeProgrammer Log

 10:14:37 : USB speed : Full Speed (12MBit/s)
 10:14:37 : Manuf. ID : STMicroelectronics

Thanks
