Chip computer wireless module

Chip computer wireless module

From time to time, my Chips don't survive a power failure. They have to be reflashed before they can boot again.

Steps

  1. Use a jump wire to connect GND to FEL;

  2. connect Chip to computer, the following device should appear in lsusb's output:

    Bus 001 Device 051: ID 1f3a:1010 Onda (unverified)

  3. from a checkout of https://github.com/NextThingCo/CHIP-tools, run:

    ./chip-update-firmware.sh -s

  4. remove jump wire, reboot, connect using screen /dev/ttyACM0 115200.

Note: perhaps pass -f as well to force downloading fresh image files.

Success output

Note: it's just one of the writing 'UBI'... steps that takes most of the time. There is also a long run of null bytes at the start of the ==Downloading new UBI line (== Cached UBI located == for subsequent runs).

== Reset after flash ==
== Force clean and download ==
== Server selected ==
== preparing images ==
== New image available ==
== Downloading.. ==
