µVISION DEBUGGER: Update of J-Link Debugger

Information in this knowledgebase article applies to:

  • J-Link Debugger


I am using a Segger J-Link to debug my target hardware from µVision. There are connectivity issues and/or sporadic lockups.


The J-Link software you are using may be outdated for the device you are using, especially if it is a newer device. The problems you see may already be fixed in the latest J-Link firmware or driver.


Updating the Segger software is a simple process and recommended as a first step in troubleshooting. Please download and install the latest J-Link driver provided by Segger.

If your issues persist, please contact our Support Team at: Keil Product Support
