In this controller TMS and SWDIO are not multiplexed. </P><P>So I have used Ulink Pro to program the controller via JTAG. However the device does not get detected via JTAG. Programming via SW is possible though. Can any one help and explain why programming via JTAG is not happening?</P></BODY></HTML> Thu, 07 Jul 2016 08:55:38 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Unable-to-program-LPC1347-using-JTAG-pins/m-p/546818#M13336 shreelaxminair 2016-07-07T08:55:38Z Re: Unable to program LPC1347 using JTAG pins. https://community.nxp.com/t5/LPC-Microcontrollers/Unable-to-program-LPC1347-using-JTAG-pins/m-p/546819#M13337 <HTML><HEAD></HEAD><BODY><P>The JTAG port provides access to boundary scan only.</P><P>CPU debugging and flash programming can be done solely through the SWD port.</P><P>This is not an SWJ-DP.</P></BODY></HTML> Thu, 07 Jul 2016 13:14:35 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Unable-to-program-LPC1347-using-JTAG-pins/m-p/546819#M13337 rolfmeeser 2016-07-07T13:14:35Z Re: Unable to program LPC1347 using JTAG pins. https://community.nxp.com/t5/LPC-Microcontrollers/Unable-to-program-LPC1347-using-JTAG-pins/m-p/546820#M13338 <HTML><HEAD></HEAD><BODY><P>Thanks for the reply.</P><P></P><P>By the way how does debugging &amp; boundary scan differ from each other?</P></BODY></HTML> Fri, 08 Jul 2016 08:31:33 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Unable-to-program-LPC1347-using-JTAG-pins/m-p/546820#M13338 shreelaxminair 2016-07-08T08:31:33Z Re: Unable to program LPC1347 using JTAG pins. https://community.nxp.com/t5/LPC-Microcontrollers/Unable-to-program-LPC1347-using-JTAG-pins/m-p/546821#M13339 <HTML><HEAD></HEAD><BODY><P>Try Wikipedia?</P><P><A href="https://en.m.wikipedia.org/wiki/Boundary_scan" title="https://en.m.wikipedia.org/wiki/Boundary_scan">Boundary scan - Wikipedia, the free encyclopedia</A> </P></BODY></HTML> Fri, 08 Jul 2016 10:42:23 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Unable-to-program-LPC1347-using-JTAG-pins/m-p/546821#M13339 thefallguy 2016-07-08T10:42:23Z Re: Unable to program LPC1347 using JTAG pins. https://community.nxp.com/t5/LPC-Microcontrollers/Unable-to-program-LPC1347-using-JTAG-pins/m-p/546822#M13340 <HTML><HEAD></HEAD><BODY><P>Ok</P></BODY></HTML> Fri, 08 Jul 2016 11:27:21 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Unable-to-program-LPC1347-using-JTAG-pins/m-p/546822#M13340 shreelaxminair 2016-07-08T11:27:21Z
