Hello,

 

I'm posting a new message because the previous one was not answered with successful connection. 

The problem is that when MCU is populated on my board with Read-Our Protection enabled, it is not possible to connect STM32CubeProgrammer v.2.21.0 to that MCU, it becomes a brick.

This option was available in the version 2.0.0. that doesn't work on Windows 11.

How can be done two step connection: 1) full erase and 2) connection ?

 

Thanks,

Alex

Why can't you connect to the chip? What happens when you try? Show relevant error messages and screenshots to show the problem.

Hello,

The MCU is soldered on my board and I have access only to UART. The CubeProgrammer v2.21.0 on Windows  11 reports the following error. The old v2.0.0 on Windows 10 allow to make two steps: full erase and connect.

Unfortunately, the version 2.0.0. doesn't work on Windows 11.

Is this option available in CubeProgrammer v2.21.0 ?

Thanks,

Alex
