Hi,

I’m using VisualGDB with OpenOCD and STM32 microcontrollers. This morning everything was fine, but now its no more possible to connect to the debugger (StLink V2).

If I click on the “Test OpenOCD Settings” button, I get this Message: “OpenOCD exited with code 1. Please check your settings.” But i did not change anything. The only thing I changed was a new driver for the CP2102 USB to UART Bridge Controller. I removed the driver, but I got still the same issue.
I also tried to disable the windows firewall as mentioned in another thread, but no success. Also a reinstall of VisualGDB und the STLink driver was not successful.

These are the logs:
