µVISION DEBUGGER: Not a Genuine ST device on STM32L053R8 Board
Information in this knowledgebase article applies to:
After updating from Keil MDK V5.27, when I try to download or debug my Nucleo STM32L053R8 board, µVision returns the following error:
Not a genuine ST Device! Abort connection
I tried changing the Connect setting (Options for Target, Debug tab, Settings) to Under Reset but that didn't help.
Please change the Connect setting to with Pre-reset for this board, then save your settings. Your board should download and debug properly now.
