3. Getting 

Started

The firmware for the on-board debug probe and Windows 7/8 driver for the virtual com 
(VCOM) port are available from http://nxp.com/demoboard/om40004 under the Software 
and Tools tab (look under “Software” download types). If using Window 7 or 8, you will 
need to install the VCOM driver by running the installer program (see installation notes 
included in the package.)

The MP board is pre-programmed with a simple program to demonstrate use of the BM 
and MP boards together. Connect a micro USB cable from connector J4 to a host 
computer or power supply to power up the board and run this program. When the program 
is running, firmly press a button on the BM board to light the associated LED (i.e. X0 to 
light D0, X1 for D1, etc.)

The rest of this section describes how to set up your board for use with MCUXpresso IDE 
and/or third party tools.

3.1  Driver installation and (optional) debugger firmware update

The MP board comes pre-programmed with a CMSIS-DAP firmware image; it is not 
necessary to update the debugger firmware image, but this can be done by following the 
steps below.

1. With the board unpowered, install jumper P5.
2. Power the board. Using File Explorer (or equivalent on Mac/Linux platforms), look at 

the available drives on your system. A device called CRP_DISABLED will appear.

3. Delete the firmware.bin file on the CRP_DISABLED drive.
4. Drag and drop the firmware.bin file you downloaded from nxp.com on to the 

CRP_DISABLED drive.

5. Remove P5, unplug then repower the board.
6. The board should now enumerate on your system - allow 20-30 seconds for this to 

complete.

3.2  Using the board with MCUXpresso IDE

To use the board during a debug session in MCUXpresso IDE, connect to the host 
computer then follow the steps below. 

Note that MCUXpresso IDE has built-in knowledge of the LPC84x part family, so does not 
require any SDK installation steps. Follow the steps below to build and run a simple 
example from the LPC84x Code Bundles provided by NXP.

1. Download the latest LPC84x Code Bundle from nxp.com: 

http://www.nxp.com/products/software-and-tools/software-development-tools/softwar
e-tools/lpc800-code-bundles:LPC800-Code-Bundles.

2. Open a new workspace in the IDE.
3. In the Quickstart panel of the IDE, click in “Import a new project from the file system”
