Firmware Update

The first time you connect to ULINKplus (for Flash downloading, debugging or setting up the debugger), you may receive the following message explaining that ULINKplus firmware should be updated. Your ULINKplus may be installed with either V1.x.x or V2.x.x firmware. The dialog that displays is slightly different for V1.x.x and V2.x.x:

V1.x.x Firmware

ULINKplus V1 Firmware Update Dialog

Click OK to update from V1.x.x firmware to V2.x.x firmware and complete the connection to ULINKplus.

 

  • If you do not allow the update, the ULINKplus Flash download or debug session terminates. To use the V1.x.x version of the firmware, in Options for Target - Debug, you must change the debug target driver to CMSIS-DAP Debugger. The download or debug session will then run, but without the full features of ULINKplus.

V2.x.x Firmware

ULINKplus V2 Firmware Update Dialog

Click OK to update your V2.x.x firmware and complete the connection to ULINKplus.

Manual Update

The ULINKplus adapter may also be manually re-programmed for use with other CMSIS-DAP V1.1 compliant debuggers such as DS-5.
