Hello, I bought a NUCLEO-F446RE Evaluation board last month. But it doesn’t work when I “RUN” or “DEBUG” in STM32CubeIDE2.1.1 environment . To solve this problem, I tried several methods supplied by GPT, I can list more information below:

Firstly, my computer is a  lenovo notebook with win11, the STM32CubeIDE version is 2.1.1, and STM32CubeProgrammer version is 2.23.0;

Secondly, the device management can list the key information showed below when I connect NUCLEO-F446RE:

Thirdly, the STM32CubeProgrammer can easily connect NUCLEO-F446RE, the figure of connecting status and log are showed below:

 However, after I closed STM32CubeProgrammer and open  STM32CubeIDE, when I click “run” or “debug”, IDE cannot connect NUCLEO-F446RE, the problem figure showed as below:

 

I feel puzzled on this issue, can you give some advice? Thanks.

Thanks for the reply by Andrew and Pavel. It really took me too much time on this problem.
I changed a PC and install these software again, the result is positive, ST-LINK can connect now, and also success to  erase, download fw etc…
ST website seems not stable these days, I cannot easily download softwares.

Are you sure it is a genuine ST-Link? 

 

after I closed STM32CubeProgrammer and open  STM32CubeIDE, when I click “run” or “debug”, IDE cannot connect NUCLEO-F446RE, the problem figure showed as below:

Is Device Manager  still showing the ST-Link as present?

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

By the serial number the ST-Link looks good.

Just be sure that you fully disconnect CubeProgrammer before trying to connect CubeIDE. Only one program can connect to ST-Link at any time, and will not find the ST-LINK if it still in use by other app. Unless you use “shared” method, which is complicated.
