Great to hear it's working. The board will power from either USB port, so no external supply is needed.
The DFU tool simply downloads the image to IRAM and then boots it. Once the board is power cycled or reset, the downloaded image is lost.

We are working on an update for the DFUSec tool that will allow you to burn images onto the boards SPI Flash or other external FLASH, or internal FLASH (1857).
The image would only need to be re-linked with a different execution address, inline with the SPI Flash versions of the examples and then downloaded to the board. After reset with SPI Flash boot enabled, the downloaded program would run.

You can refer my blog for more info, http://microcworld.blogspot.com/2012/06/programming-lpc4330-xplorer-using-dfu.html

The blinky code provided in NGX website can be used with this dfu tool.

thank u... i downloaded the blinky code in lpc4330. Now to run the code from internal Ram what will be the boot selection switch? whether it is same as OFF,ON,OFF,ON or some other setting?
i tried with OFF,ON,OFF,ON setting, it doesn't work... can i power the board via usb1 to run the sample blinky code or i need to use external power supply to it?

You need to use the DFU boot mode for the chip and the correct USB connector to use the DFUsec tool.
Start the tool and plug USB into the board and the "No CONN" shuold change to "High speed USB" if a device was found.

I don't have access to a LPC43xx NGX board, but I do have a 18xx board and they are probably very similar.

Try these settings: 1-off, 2-on, 3-off, 4-on
Use the USB connector next to the audio connectors for DFU boot.

I've attached a version of blinky that works on the NGX18xx that hasn't been tested on the NGX43xx, it should work on the 43xx. The is a raw binary meant to be executed from IRAM, so you'll have to use the auto-header append option of the DFUsec tool when booting this image. No guarantees on it working, but let us know if it does.

Try the DFU download tool. You can find it here: http://www.lpcware.com/content/project/dfu-downloadupload-lpcdfusec-tool

You will need to set the boot jumper block (J4) to boot up via USB. You will find the required settings in the UM.
