QUESTION

I want to use ULINK2 (or ULINK-ME) to debug my Freescale Kinetis TWR-K40X256 (or TWR-K60X512) board and I have a 10-pin to 20-pin ribbon cable, but the 20-pin connector on the cable has a plastic plug inserted at pin 7, so it won't fit on the Freescale board's JTAG connector. How can I use this cable?

ANSWER

Some early 10-pin to 20-pin ULINK cables have plastic plugs installed at pin 7 on both the 10-pin and 20-pin ends. You may remove the plugs using a needle or the point of an XACTO knife. To do this:

  1. Position the point of a needle (or XACTO knife) under the exposed end of the plug.
  2. With the point of the needle touching the side of the plug, tip the needle (or XACTO knife) down. This should move the plug up and out of the connector slightly.
  3. Repeat this 3 or 4 times until the plug is out.
