User Manual
7. Ensuring the LPCXpresso802 is connected to the host computer, click Debug in the
Quickstart panel. The IDE will search for available debug probes. Select the debug
probe that appears for your board, then click OK. Note that the IDE will remember
your selection for the next time you debug this project, so will not prompt for this
again, unless it cannot find the board.
8. The code will execute to main. Press F8 to resume and run the program. You will now
see the User LEDs light, each color in turn.
3.2 Using LPCXpresso802 with 3rd Party IDEs
Once the board debugger firmware has been installed (as described in
Section 3.1
), to
use the board during a debug session in MCUXpresso IDE, it can be used with 3rd party
development tools. Set up will vary between Development Tools, but the board debug
probe should supported as a CMSIS-DAP probe in all cases).
Code Bundles, including sample projects for Keil MDK and IAR EWARM, are available
from NXP’s website at
http://www.nxp.com/products/software-and-tools/software-development-tools/software-to
ols/lpc800-code-bundles:LPC800-Code-Bundles. Refer to the readme files provided with
each code bundle in order to build/debug.
When using Keil MDK, install the Device Pack for the LPC802 (version 1.6 or later) before
attempting to use the board.
When using IAR EWARM, ensure that you have version 8.20.1 or later in order to have
LPC802 device family support.
3.3 Debugger firmware update (optional)
The MP board comes pre-programmed with a CMSIS-DAP firmware image; it is not
normally necessary to update the debugger firmware image, but this can be done by
following the steps below.
1. Hold down the reset button and keep it held down while applying power to the board.
Release reset. Using File Explorer (or equivalent on Mac/Linux platforms), look at the
available drives on your system. A device called CRP_DISABLED will appear.
2. Delete the firmware.bin file on the CRP_DISABLED drive.
3. Drag and drop the firmware.bin file you downloaded from nxp.com on to the
CRP_DISABLED drive.
4. Repower the board.
5. The board should now enumerate on your system - allow 20-30 seconds for this to
complete.
4. Debug
Probe
Later production LPCXpresso802 boards have been programmed with an updated
version of CMSIS-DAP, and a standard UART VCOM port. It is recommended that the
LPC11U35 firmware be updated to the latest version available on the LPCXpresso845
board page, under the Software and Tools tab. See
Section 3.3
for information on how to
update the debug probe firmware.
