Each board’s landing page can be found at the URL https://www.nxp.com/demoboard/ where is the board’s orderable part number (OM13092, OM13098, OM13094, OM40003 or LPC54S018-EVK.) 3.2.1 Installation steps for use with MCUXpresso IDE 1.
UM11035 NXP Semiconductors LPCXpresso boards for LPC546xx/LPC540xx/LPC54S0xx families of MCUs 3.2.2 Installation steps to use Keil and IAR tools 1. Download and install LPCScrypt or the Windows drivers for LPCXpresso boards (http://www.nxp.com/lpcutilities). This will install required drivers for the board. 2. Ensure JP5 is open to force the Link2 Debug Probe to boot from internal flash. 3. Ensure jumper JP2 is fitted in position 1-2 (local target powered), and JP1 is not installed (target SWD enabled).
UM11035 NXP Semiconductors LPCXpresso boards for LPC546xx/LPC540xx/LPC54S0xx families of MCUs The Link2 Debug Probe is implemented using an LPC432x MCU (circuit reference U21), which provides a high speed USB port interface to the host computer that runs the development tools. This device is not intended for developer use, and should only be used with approved firmware images from NXP.
