I have had good success developing and debugging LPC1114 board.
However, now i need to program the project into the lpcexpresso for stand-alone operation.
I would first assume I need to build as release. But then instead of debugging, i need to program the board so it can be run without usb debugging connected.
I would assume I can power the LPC1114 from 3.3v on any via labelled 3.3v, but program does not run.

Where is the procedure?

To program the flash without using the debugger, read this:

If you want to completely disconnect the LPC1114 from the LPC-Link, and then to program the device, there are two methods:
1. Provide an SWD debug connector on your target board and connect the small 10-pin connector on the LPC-Link board to it. Then use the instructions above.

2. Provide a serial port on your target board and use FlashMagic to program the flash via it.

It seems my problem was feeding DC power into a 3v3 pin.
I tried feeding 5v dc power into J6-2, and all is fine with LPCexpresso running by itself. I did not need to flash the board outside of eclipse, only debug it from release build and then disconnect.
However under this condition of feeding DC 5v to j6-2, the LPC-Link side seems to be running without usb connection. But it appears to be no problem since its not doing anything to jtag signals.

This might be something useful to document for others who want to run LPCExpresso (by itself) without debug connection.
