Unable to program LPC1347 using JTAG pins.

[shreelaxminair]

Hi all,

I am using LPC1347. In this controller TMS and SWDIO are not multiplexed.

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?

Try Wikipedia?

Boundary scan - Wikipedia, the free encyclopedia

Ok

The JTAG port provides access to boundary scan only.

CPU debugging and flash programming can be done solely through the SWD port.

This is not an SWJ-DP.

Thanks for the reply.

By the way how does debugging & boundary scan differ from each other?
