  • 2. Boot the MBED HDK into CRP DISABLED mode by shorting JP3 while connecting the USB Cable to USB1. A Image:CRP_DISABLED.png drive should appear.
  • 3. Program the Interface firmware by deleting the firmware.bin file and copy lpc11u35_vcom.bin to the CRP DISABLED disk.
  • 4. Reboot the Interface by disconnecting and reconnecting the USB1 cable without JP3 shorted.
  • 5. Finished!
