LPC-Link_2

Overview

This firmware allows users to take advantage of most J-Link features like the ultra fast flash download and debugging speed or the free-to-use GDBServer, by using a low-cost LPC-Link 2 platform for developing on evaluation boards.

Key features

  • Supports all Arm-based NXP devices that are also supported by J-Link LITE [More..]
  • JTAG, SWD + SWO supported
  • Fully compatible with and same features as J-Link LITE [More..]

Getting Started with LPC-Link 2

In order to get started with LPC-Link 2 just a few steps are necessary:

  • Download LPCScrypt here.
  • To make sure that LPCscrypt uses the latest LPC-Link2 firmware, please replace the J-Link firmware images located in:
    • LPCScrypt_InstallDir\probe_firmware\LPCXpressoV2\ and
    • LPCScrypt_InstallDir\probe_firmware\LPCLink2\
  • (Files may need to be renamed after download, to match the ones in LPCScrypt)
  • Set the eval board into DFU boot mode. How is explained in the respective board manual.
  • Connect LPC-Link 2 to the PC.
  • Execute %LPCScrypt_InstallDir%\scripts\program_JLINK.cmd
  • Follow the instructions given by the script.
  • Power-cycle LPC-Link 2. It will now enumerate as a J-Link.

Limitations

The firmware making the LPC-Link 2 J-Link compatible has some limitations in contrast to an original, industry leading SEGGER J-Link:

  • May be used with ARM based NXP devices only.
  • Only debugging on evaluation boards is allowed. Debugging on custom hardware is not supported and not allowed.
  • No production flash programming support.Unlimited breakpoints in flash available for evaluation only.
  • No support is given.

By using an original SEGGER J-Link Pro, J-Link ULTRA+ or J-Link PLUS, all these limitations will be gone. Learn more about J-Link
