ST-Link V2 Debugger- USB Communication issues after hours of use

Hello,

I am using the ST-Link V2 debugger to run on target unit tests. I have updated my windows drivers to the latest and the firmware on the debugger has been updated to the latest as well. Tests are compiled via IAR (v7.2) and then run on device via IAR command line tools using ST-Link as the debugger. This process is repeated over 8+ hours as there are a lot of tests and they need to be compiled and run in batches. I have no issues for a couple of hours but eventually the debugger stops being responsive. When it gets in this state I tried communicating with it via ST-Link Utility but I get a USB communication error message. Has anyone else experienced similar issues? Any ideas to try and get this to work consistently? Thanks, Marko #st-link #- #swd Note: this post was migrated and contained many threaded conversations, some content may be missing.

You might observe it's a thread from 2 years ago, and you're asking the guy who wrote 'I have a truly marvelous demonstration of this proposition which this margin is too narrow to contain' when he was last at the forum 5 months ago.
