Can't debug in System workbench for STM32.
Hi, 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 also check that 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 :
