ST-LINKv2 not working fine after updating

Question asked by Jose Angel Salvador on Oct 23, 2017

Hi guys, I'm new here and I need some help if possible.


I have some trouble with ST-LINK v2 device. I'm using MacBook Pro with Bootcamp running Win 10. When I start st-util from macOS console everything works fine, st-link shows me that a device is connected (now I'm testing with a STM32F103C8T6), but when I try to program it, there's an strange error which says that was unable to erase flash (I have 2 identical MCU's, working OK after updating and I have the same trouble with both of them). When I start on Win10, and load ST-LINK Utility with the GUI, I get an USB communication error, and the st-link is unable to recognise my device. Is there any solution for my problem? Is it possible to downgrade the ST-LINKv2? (I tried with an old updater, but I get an 'ST-LINK corrupt content' error.

I think and I've read is something related with the new firmware, but I'm not 100% sure. Someone can help me?
