Connecting the MCBXC88x

To use the MCBXC88x Evaluation Board with ULINK, you must:

  • Verify that the ULINK VCC jumper (inside the ULINK housing) is connected to Ext VCC.
  • Connect ULINK to the PC via a standard USB cable.
  • Connect ULINK to the JTAG connector of the MCBXC88x board.
  • Make sure that J3 - BTL is OFF.
  • Connect power to the MCBXC88x Board using a standard USB cable.

The following picture shows how to connect ULINK to the MCBXC88x Board.

ULINK and the MCBXC886 Board


  • If your application program puts the XC88x device in Power Down or Idle mode, the OCDS in the Infineon XC800 device (and subsequently the ULINK) stops working. Therefore, do not put the XC88x device device into the power saving modes during the software development cycle.
