this is Buster Lite on RPi Zero W

The examples do work on rpi0-raspbian-stretch-edgetpu-1.9.2.img.gz (ancient OS image)

@cipy It's worth mentioning that this is an unofficial platform that we create to make earlier versions of our software easier for beginners with rpi. It is very hard to maintain this repo right now since our software stack grows far beyond jut rpi users. Also it is not a popular request anymore. The last image contains a very old version of libedgetpu runtime (11). We are now at 14, you should be able to easily use the accelerator with the getting started page: https://coral.ai/docs/accelerator/get-started

Please also check requirement section: https://coral.ai/docs/accelerator/get-started/#requirements

Thanks @Namburger

I'll try it later on RPi 3B+ and 4B

The biggest advantage with supporting RPi Zero is that Zero is very good for edge computing

[Namburger]

@cipy I see, I guess we moved away from pi0 because lack of demand. But anyhow, this image should works for the pi0 in theory, it'll just be running an older version of our library and we'll soon drop supports for older version of python. I remember seeing issues like this with our older releases but it's so long ago :) Would something like this answer: https://github.com/google-coral/edgetpu-platforms/issues/10#issuecomment-509025130 help?

Hi, same issue with the RPi0-W using Raspbian Buster May you share the makefile and Dockerfile used to compile the edgetpu for RPi0?

[hjonnala]

Closing the issue since the edgetpu is deprecated and due to lack of official support for Raspberry Pi Zero. Sorry for the inconvenience.
