LPCXpresso range of development boards from NXP which include the LPC-Link 2 interface can be firmware updated to include mbed USB disk programming capabilities.

Below is a quick guide to how to carry out this update.

Requirements¶

• A Windows computer
• Download and install the latest DFU Boot drivers
• Download and install the latest NXP DFU Download utility

Instructions¶

1. Fit jumper JP3¶

2. Connect the "link" micro-B connector to the PC¶

3. Run dfusec.exe¶

• Browse to the correct Algorithm file (the correct one should be selected by default)
• Download the binary for your board from the list below, and then :
  • Browse to the binary
  • Set the parameter : "Address"
  • Set the parameter : "Size"
• Press the start button on the PC application... wait... done :-)

4. Remove the jumper JP3 and unplug/plug in the LPCXpresso¶

You should now have an mbed flash disk for drag and drop programming
