9.1.1 Bootloader Mode
The BOOT LOADER (J9) jumper allows the user to set the onboard PIC18F14K50 in bootloader mode and to
program it. One can then update the gateway with the latest driver from Semtech website or set its own
solution

using the SPI interface (see 7.1. Prototyping Area ).
By default, the jumper is not connected.
To enter in bootloader mode, shortcut the BOOT LOADER (J9) jumper and restart the PIC by unplug-plug the
SUPPLY jumper or disconnect-connect the USB cable (see
Figure 10 on page 14 ).
