Spark Photon displaying white screen & "Serial Error: Write timeout" in log

Troubleshooting
1

My original BrewPi Spark with the Photon controller is displaying a blank white screen. I’ve updated the Photon firmware to 0.7.0. I can access it via screen to run the WiFi setup. It has a valid IP address on the WiFi, and I can ping it, but i can’t communicate with it over TCP 6666. I can serial into it from the pi (docker container), but it’s giving me write errors (below). I did use the --privileged flag when creating the container so it should have access to the USB.

Any advice? Is this failed hardware?

It looks like you are not running the BrewPi application, but have the Particle factory firmware with a blank application.

Please run the following on the pi to get the latest version of the BrewPi firmware:

docker run -it --name brewpi-dfu --privileged -v ~/brewpi-data:/data --rm brewpi/brewpi-raspbian python utils/flashDfu.py --trigger

docker run -it --name brewpi-dfu --privileged -v ~/brewpi-data:/data --rm brewpi/brewpi-raspbian python utils/flashDfu.py --noreset

If you are not running this from a raspberry pi, run this instead:

docker run -it --name brewpi-dfu --privileged -v ~/brewpi-data:/data --rm brewpi/brewpi-ubuntu python utils/flashDfu.py --trigger

docker run -it --name brewpi-dfu --privileged -v ~/brewpi-data:/data --rm brewpi/brewpi-ubuntu python utils/flashDfu.py --noreset
