[BUG][V2.20] -noreconnect doesnt work on Windows

I recently tried to use -noreconnect via the cli on windows and it still attempted to reconnect.

I was connected via UART and programming option bytes. 

Here was the command I used:

& "C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe" -c port=COM14 br=115200 -noreconnect -ob ndbank=0x0

I see that there was fix put in for linux. Im wondering if the same bug exists on Windows.

Thanks,

Daniel

I encountered the same issue with -noreconnect still attempting to reconnect in v2.20 on Linux.

I am programming option bytes on the U575 via USB.

The command I ran and its output are included as an attachment.

I'm having the same issue when using API v2.20 on Windows.

Thanks for the confirmation and work arounds.

I assumed posting here was filing the bug with ST. Is there a different place for that?

I'm using STM32CubeProgrammer API but I don't find the command to no reconnect to device after OB programming. Could you list the procedure to do that? Thanks

Just like to echo this thread and add that the -noreconnect command still doesn't seem work for STM32CubeProgrammer v2.21.0 on Windows 11

Looking forward to a fixed release.

Thanks,
Eric
