In detail, you can connect each&nbsp; JTAG signal pin to 74VT244A so that the driving capability can be enhanced to enllarge the line length.</P><P>Hope it can help you</P><P>BR</P><P>Xiangjun Rong</P></BODY></HTML> Wed, 23 May 2018 02:43:03 GMT https://community.nxp.com/t5/Digital-Signal-Controllers/How-to-use-3-feet-extension-cable-for-programming-with-USB-TAP/m-p/769849#M1258 xiangjun_rong 2018-05-23T02:43:03Z Re: How to use 3 feet extension cable for programming with USB TAP? https://community.nxp.com/t5/Digital-Signal-Controllers/How-to-use-3-feet-extension-cable-for-programming-with-USB-TAP/m-p/769850#M1259 <HTML><HEAD></HEAD><BODY><P>Hi Alon</P><P>Is it the ribbon cable that you are extending?</P><P>Can you give more details on the problem?</P><P>What happens when you try to program?</P><P>Some things to try:</P><OL><LI>Try shielded ribbon cable.&nbsp; Probably with shield grounded only at your target DSC board.</LI><LI>Slow down the programming speed of the USB TAP as shown in the screenshot.&nbsp; Maybe try 500 or keep going down until it is reliable.<span class="lia-inline-image-display-wrapper" image-alt="DebugConfig_USBTAP-Properties.png"><img src="https://community.nxp.com/t5/image/serverpage/image-id/23723iF0075728C0203BBB/image-size/large?v=v2&amp;px=999" role="button" title="DebugConfig_USBTAP-Properties.png" alt="DebugConfig_USBTAP-Properties.png" /></span></LI></OL><P>Pete</P></BODY></HTML> Thu, 24 May 2018 14:21:33 GMT https://community.nxp.com/t5/Digital-Signal-Controllers/How-to-use-3-feet-extension-cable-for-programming-with-USB-TAP/m-p/769850#M1259 dynapb 2018-05-24T14:21:33Z
