The VPK120 board includes an onboard system controller. A host PC resident system controller board user interface application is provided on the VPK120 Evaluation Board website. This board user interface application enables the query and control of select programmable features such as clocks, FMC functionality, and power system parameters. Users should not change the default system controller image as that could potentially cause the board damage if proper procedures are not followed. Contact support if this image needs to be updated.

A brief summary of these instructions is provided here.

  1. Ensure the Skyworks/Silicon Labs VCP USB-UART drivers are installed. See the Silicon Labs CP210x USB-to-UART Installation Guide (UG1033).
  2. Download the board user interface host PC application from the VPK120 Evaluation Board website.
  3. Connect a USB cable to VPK120 USB-UART USB-A connector (J344).
  4. Power-cycle the VPK120.
  5. Launch the board user interface application.

The board user interface application UI is shown in the following figure.
