Connect to custom board STM32L053 - STLINK-V2 - SWD
Hi All,
The following information may help. It might be wise to check even if it does not fix the issue :
Some USB 3.0 Controllers (such as NEC/Renesas) have a bug that prevents the binary to be downloaded to the board (whereas ST Link Utility works well).
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 :
