3. Getting
started
The module is pre-programmed with a simple program to blink the user LED, indicating
that the target MCU is running. Connect a micro USB cable from connector J8 to a host
computer or power supply to power-up the board and run this program. For information on
how to get started with Amazon FreeRTOS, please follow the links provided at the main
board page on NXP’s website (http://www.nxp.com/demoboard/OM40007) under the
Software and Tools and/or Getting Started tabs.
Code can be downloaded and debugged on the LPC54018 MCU using a debug probe
that conforms to the standard Arm Cortex 10-pin debug connector. Amazon FreeRTOS
and MCUXpresso SDK packages are available for MCUXpresso IDE, IAR EWARM and
Keil MDK at https://mcuxpresso.nxp.com. At the Amazon FreeRTOS github site tutorials
are provided for this module (as mentioned above); although not all tool chains are shown
in the Amazon example, IAR, Keil and MCUXpresso IDE are all supported. SEGGER
Development Studio may also be used with the MCUXpresso SDK; please contact
SEGGER for more information.
The following debug probes can be used with those development and the module (check
compatibility between debug probe and IDE used):
•
LPC-Link2 (OM13054) debug probe from NXP or Embedded Artists
•
SEGGER J-link probes
•
P&E Micro probes
•
Keil ULINK2 probes
•
IAR i-Jet probes
•
Debug probe built into a baseboard, such as the OM40006 IoT Module Baseboard
(check the specific base board being used)
Other debug probes may also be supported by IAR and Keil tools; refer the websites of
these companies. For more information (check for LPC540xx family support).
