Thank you for giving feedback to the stlink project.

NOTE: In order to offer sufficient and the best possible support, please read /CONTRIBUTING.md and follow the given instructions before submitting a ticket.

Bug reports and/or feature requests will be deleted, if they violate our contribution guidelines and if no issue-template is used! Thank you for your support.

  • I made serious effort to avoid creating duplicate or nearly similar issue

In order to allow developers to isolate and target your respective issue, please take some time to select the check boxes below and fill out each of the following items appropriate to your specific problem.

  • Programmer/board type: [STLINK V2J29S7]
  • Operating system an version: [Windows 11 21H2 22000.978]
  • stlink tools version and/or git commit hash: [v1.7.0 Release date: 2021-04-25]
  • stlink commandline tool name: [st-trace]
  • Target chip (and board, if applicable): [STM32F407VET6]

Further we kindly ask you to describe the detected problem as detailed as possible and to add debug output if available, by using the following template:

Step 1:
Begin reading a trace and then end the application using Ctrl+C

C:\STLink Tests>st-trace.exe
libusb: info [winusb_get_device_list] The following device has no driver: 'USB\VID_8087&PID_0025\6&1143EA6&0&4'
libusb: info [winusb_get_device_list] libusb will not be able to access it

2022-09-28T17:42:11 INFO trace.c: Reading Trace
Application is starting
^C

Step 2:
Reconnect. Sometimes st-trace is able to get through and it will reconnect correctly, usually I will end up with LIBUSB_ERROR_TIMEOUT error and then LIBUSB_ERROR_PIPE when I will pull USB cable out of ST-Link device

C:\STLink Tests>st-trace.exe
libusb: info [winusb_get_device_list] The following device has no driver: 'USB\VID_8087&PID_0025\6&1143EA6&0&4'

By sending termination signal using ctrl+c the st-trace.exe will be left hanging in the memory or it won't send ST-Link itself a signal to stop logging. This means that st-trace is unable to reconnect to the busy ST-Link. Pulling USB out of ST-Link and connecting it back will cause that it is possible to reconnect and log again.

Expected action: Some cleanup code, which would close / stop ST-Link logging before exiting the st-trace.exe program.

Could you recreate the issue with verbose output using the following command?
st-trace.exe -v

Could you give some information about libusb with the following command?
apt-cache policy libusb-1.0*

@simplerobot: if that’s Windows, there’s no apt-cache.

Here it is starting correctly in verbose mode. I also updated STLink via ST-Link Utility on firmware V2J33S7 to see if it will resolve the issue. It did not, but now I need to specify clock on 168MHz during st-trace start

Here it is reconnecting in verbose mode and getting stuck. I did not pulled out USB, I only let it timeout.

Here I made exactly same test with 64-bit version of binaries stlink-1.7.0-x86_64-w64-mingw32.zip release. It will get stuck as well.

Also what I see on ST-Link itself:

  • I can connect and work with it if LED of ST-Link is red or bright green
  • When will tracing start, LED will turn dim green (probably blinking very fast)
  • When I stop tracing, LED will stay dim green. Sometimes I am able to reconnect, usually this will cause that ST-Link is stuck and st-trace can't reconnect and I need to pull the USB from ST-Link and pull it back to reset it.

Additionally tested connecting directly to USB on motherboard (ST-Link is usually connected via the USB-Hub), got same issue with stuck ST-Link.

I think the problem is with the windows signal handling. I think the fix is simple, but I don't have a good way to reproduce this issue or verify the fix.

Issue details:
I believe the windows signal handler should return TRUE instead of FALSE to indicate that the signal was handled successfully. By returning FALSE, the default handler gets called which calls ExitProcess before giving our process a chance to cleanup.

Note: I believe st-util should have the same issue: windows signal handler

@simplerobot I'll have a look at it soon.
If you fancy, you may have a look at some other remaining issues. It would be great if you could help.
Some may be about to be solved, but need some additional input.

Ok, so we'd need someone to test this.
With a view on his GitHub activity, I suppose @jared52005 may no longer be available...
