Hi. My version of IDE is 1.4. My board is NUCLEO F-446RE. I've updated ST-LINK firmware without mass storage (as was proposed in another topic). Yes, I've read many other related topics but ... nothing helped. PLEASE help I'm absolutely stuck!

[OSamu.1]

Here is what I get:

The debugger uses STM32CubeProgrammerfor programming (flashing) the MCU. Looks like STM32CubeProgrammer cannot be found or the file is broken. You could check that by following the blue path in File Explorer. Try uninstalling, deleting all files under C:\ST\STM32CubeIDE_1.0.0\STM32CubeIDE\ and re-installing from scratch.

If you want more detailed analysis, you could in the Debug configuration Debugger tab enable "Log to file". This logs to a file but also increases verbosity level.

[OSamu.1]

Uninstalled, deleted ST folder and installed STM32CubeIDE 1.4.

As a result:

AV software?

[OSamu.1]

Already tried :(

[mattias norlander]

Does CubeProgrammer work in the directory if you were to load the binary directly using command-line interface? It is installed in the path that you list above. Maybe make some basic checks?

As quick-fix are you able to use OpenOCD instead?

Let us know your findings. If the bundled CubeProg CLI does not run well stand-alone either, then maybe re-install CubeIDE. Since you upgrade all the way from 1.0.0, maybe you can install 1.4.0 in parallel and see if that works...

[OSamu.1]

With openOCD it doesn't work. Unfortunately.

Thank you very much to everyone who gave me his answer. I very appreciate it. Yesterday after several tweaks I managed to stun my Windows. After reinstallation of it and installing STM32CubeIDE everything works.
