DFU mode read out protection

Hello, 

I am trying to connect to the STM32F072C8T6 microcontroller via USB in the STM32CubeProgrammer, however I am getting:

"Device is under read out protection ! If you want to disable RDP please reconnect with Read Unprotect enabled"

So, when I check the Read Unprotect (MCU) checkbox, I get:

"Please Power off Power on your device."

After turning the power off/on, I see the same messages. I cannot connect to the MCU via USB in the STM32CubeProgrammer.

I have tried different versions of STM32CubeProgrammer:

  • v2.16.0
  • v2.15.0
  • v.2.13.0
  • v.2.10.0
  • v.2.8.0

Moreover I tried on second computer with Windows 11 and I have the same issue.

I'm trying to connect my custom board, but I also checked another hardware board (BluePill ) with the same STM32F072C8T6 MCU and it doesn't work either.

Interestingly, using the DFU-util v0.8 program I can connect to the MCU and successfully read/write memory:
