I purchased this board (http://shop.ngxtechnologies.com/product_info.php?products_id=105) about a month ago with an LPC-Link2 debugger board. It all worked perfectly out of the box. Shortly after I changed to a different eval board, but am now switching the project back to this one. Now, however, I can't seem to run anything on the NGX board.

The LPC-Link2 lights up when connected to the computer, and the other board's power LED also lights up when that board is powered from a wall wart (just to avoid any potential com port confusion).

I am using LPCXpresso v7.9.2 and this project was made in the same version.

In LPCXpresso, when I do Debug As > NXP MCU Application (with all the debug configurations deleted), it asks me to choose which CMSIS-DAP emulator to use. It sees the LPC-Link2 and lets me continue. Once the project builds (with no errors), I get two popup windows saying:

Error reported by target

Error message from debugger back end:

I've been looking through the forums and tried everything that seemed reasonably related. I could not find any helpful information on the pages that the "Help on this error..." button takes me to (https://www.google.com/search?q=02:%20Failed%20on%20connect&sitesearch=http://www.lpcware.com/content/faq/lpcxpresso&gws_rd=ssl)

Any thoughts?
