Hello,

I have connected JTAG connector J6 in LPC-Link2. When I program the target system is a message that is in the SWD.

How to switch the JTAG mode ?

There is a bug in what is reported by the debug driver. It is reporting swd regardless of what type of connection. This is fixed in the next release.

If jtag is correctly selected in the debug configuration, you will be prompted to select a core.

Changed as shown in the link on the JTAG, but still program and debugger in SWD.

When I push the icon "Program Flash" option "Conection options -> Use JTAG interface" is inactive.

What could be the cause of working only in SWD ?

BTW. I program LPC4088, which is certainly JTAG.

SWD vs JTAG is selected in the IDE - it is not something you switch physically.

When starting a debug session, The IDE will automatically select the most appropriate connection type for your target (some LPC parts are StD only, some are both SWD and JTAG, and some are JTAG only).

See http://www.lpcware.com/content/faq/lpcxpresso/launch-configuration-menu

On the Debugger tab (at the bottom of the dialog - you will need to scroll) you will see a drop-down selection box. Select the JTAG option from the drop-down.
