I picked up one of these assuming it was possible.  Should have researched this a bit further since now it doesn't appear possible.  I have a target board with a LPC822 on it I'd like to do some initial debugging on.  Can I disable the LPC824 on the eval board and run SWD, SWCLK, and Reset to my target?

Tnx,
Dave

Yes.  It works.  ;-) 
Apparently the force was with me!

Yes.  It works.  ;-)  3 small cuts on the back of the board (SWDIO, SWDCLK and RESET) and the 10 pin header plugged into my target.  I will definitely order an LPC Link 2, but at least I can work until it gets here and I don't have to pay for overnight shipping.

Apparently the force was with me!

The LPCXpresso-MAX family of boards provide a powerful and flexible development system for some of NXP's low end MCUs....
Built in CMSIS-DAP based debug probe, based on the NXP LPC11U3x MCU.  :)

That's what I was thinking.  I have to develop a small app very quickly.  I'll order the LPC link-2 but I may just hack the xpresso824 board for the weekend.  I have two of them, so... no big loss if I trash it.  I guess the only question is is if the debugger is somehow locked to the target part on the board.  I know that some of the boards from NXP's soon to be partner do that.

Schematic shows a SWD target connector  :O
If you cut the traces from target connector to the target this connector should be able to debug another target  :)

Thanks for the quick reply.  Yeah, I was in a hurry.  Ordered the wrong thing :(   Thankfully a small amount of money either way.
