OpenOCD stopped working
Hi, I remember an old post with similar issue :
Some USB 3.0 Controllers (such as NEC/Renesas) have a bug that prevents the binary to be downloaded to the board.
Please, may you check you are using the latest version of the controller to fix this issue.
Note that sometimes, the device manager seems to be up to date but the issue is fixed after executing the setup provided in the zip.
It can be downloaded from :

Keep in mind that it is not possible to get both STLinkUtil and SW4STM32 connected to the target simultaneously.
