Using an LPC-Link2 as an LPC4370 evaluation board

Senior Contributor I

As well as being a standalone debug probe, the LPC-Link2 can also be used as a simple LPC4370 evaluation board. The following notes may assist in such usage.


Debug connection


Make sure that you have connected the JTAG/SWD cable from your debug probe to the target LPC-Link2's connector J2 (and not J7!). Thus if you are using a two LPC-Link2s, one as the debug probe and one as the target - you need to connect J7 on the debug probe to J2 on the target.


Flash Memory


The LPC-Link2 has a 1 MB SPIFI flash (Winbond W25Q80BVSSIG) mounted on it (at address 0x14000000). You can program this in LPCXpresso using the "LPC18_43_SPIFI_GENERIC.cfx" flash driver. Make sure that you have a jumper fitted to JP1 though. The XML file in the attached can be used to set up the memory configuration of your project for this memory/flash driver.




If powering the target LPC-Link2 via USB, then we would normally suggest doing this from a powered USB hub that is not connected to your PC. This will prevent any chance of the target LPC-Link2 being seen by the tools running on the PC as a usable debug probe. If debugging the target LPC-Link2 using another LPC-Link2, then you can supply power from the debug LPC-Link2 if you fit jumper JP2 (though this is not generally recommended if you have additional hardware attached to the target LPC-Link2).


Simple example application


A simple blinky application for the LPC4370/LPC-Link2 can be found in the attached Download and save the zipfile to your local disk, then use the LPCXpresso "Quickstart Panel -> Import project(s)" option to import it into your workspace. In order to build this, you will also need to import the CMSIS_LPC43xx_DriverLib library project from the LPCXpresso examples into your workspace. For details of importing, building and debugging projects - please see the LPCXpresso User Guide, provided within the product itself.


The LPC-Link2 is also a supported target board for our LPCOpen software platform. You can download example code from our LPCOpen pages.
