HOWTO: updating the firmware of the PiVoyager

The following instructions explain how to update the firmware of the PiVoyager.

1) Remove all power sources to the PiVoyager/Raspberry Pi, both battery and USB.

2) While holding down the side button of the PiVoyager, connect back the battery to the PiVoyager.

3) The 3 indicator LEDs on the PiVoyager should blink in sequence, one after the other. Release the side button.

4) Connect USB power to the PiVoyager. The 3 indicators LEDs should continue to blink.

5) Access your Raspberry Pi command line and download the new firmware.

For example, to download the firmware released on May 30th, 2020, you can use:

wget https://www.omzlo.com/downloads/pivoyager-firmware-20200530.bin

6) Upload the new firmware to your Raspberry Pi with the command pivoyager flash write <firmware>, replacing <firmware> with the name of the downloaded file.

If all works well the output of the command should look similar to this example:

pi@raspberrypi:~ $ pivoyager flash write pivoyager-firmware-20200530.bin
Erasing pages: [############]
Writing: [#################################################################################################################################################################################]
Reading: [#################################################################################################################################################################################]
Flash content verified.
OK

7) Cleanly shutdown the Raspberry-Pi, and unplug all power sources (USB and battery).

The PiVoyager is now ready to operate with the new firmware.
