LPC LINK-2 error in connecting to LPC54606 using JTAG

hemanthvasista — Mon, 07 Dec 2020 13:22:00 GMT

Hello ,

I am using LPC54606 based custom board. I am unable to program using the LPC Link-2 using JTAG.

Attached is the error message in MCUexpresso and the log of the error in Redink server.

Error in MCUexpressoSchematic

Also could you confirm the schematic attached?

As common with all ARM Cortex-M parts, JTAG is not used for debug - only boundary scan. Instead it uses SWD. See

Are there any way I can use JTAG in LPC54606? I remember to have used JTAG in LPC1768/88 controllers

In case of SWD,

I would need following pins:

1. SWCLK

2. SWDIO

3. SWO

Could you confirm? Also these pins are not overlapped with JTAG pin?

There is no way to use JTAG, for debug, in LPC54606.

The document I linked in my first reply, should give you all the information you require to create your debug circuit.
