SWD without target board

I'm using a LPC11C24. I have a project that compiled and ran fine on the development board and I am now trying to move it to a seperate board. I split the development board in two and connected the SWDIO, SWCLK, Reset, and ground pins of the debugger portion to the corresponding pins on the micro.

When I try to debug the project, I get an error that says "Error launching Debut/blinky.axf 03: Failed on chip setup: Ec(01). Invalid, mismatched, or unknown part:"

Is there something else I have to do with the LPC-Link before I can connect it to a chip that is not on a target board?

I'm not sure what I am doing wrong. The origional settings of the micro have not been changed from the packaging.

Did you change your MCU setting to 11C24?

Your target board is nothing special for LPC-Link.
You just have to add a power supply and connect 4 wires for SWD, Reset and GND.

That's all :)

The project should be set to the 11C24. I had a 11C24 target board and it was able to compile/debug on that board.

All I did was power up the chip, connect the 4 wires and try to debug, but I am still getting that error.

I'm going to hook up the LPC-Link back up to the target board and and see if that still works.

Did you scope VDD, SWCLK, SWDIO and Reset ?

How are clock and power on the target?

I'm just about to start laying out an 11c24 pcb, so curious if there are any gotchas (but I doubt it).

The same exact setup worked when I attached the LPC-Link back to the target board with the same project. I see information on the SDW lines that looks alright. The reset line never goes low though when I try to enter debut mode.

In the board that I am using, PIO0_1 is tied high and PIO0_3 is tied low. I don't think this should matter as PIO0_1 is high. I changed these pins to just open like it is on the target board, and I get the same results.

Sighhhh, I found the problem. I had not set up the new board myself, and I wasn't told that they changed the 11C24 out for a 11C22. Sure enough, that fixed it right away. Thanks for the help, even with the dumb mistake. Thanks Zero for the insight on SWD.
