Not working Khadas VIM3

[ihlej]

Board Name

Khadas VIM3

Steps

I am basing my installation procedure on this guide, even though this is not a Pi, because I cannot find anything for anything but Pi, nor any info for how anything differs for non-Pi. Colleagues of mine have supposedly successfully used this guide before.

1. sudo apt-get update
2. sudo apt-get -y upgrade
3. sudo apt-get install python3-pip
4. sudo apt install --upgrade python3-setuptools
5. pip3 install --upgrade adafruit-python-shell
6. sudo apt-get install -y i2c-tools libgpiod-dev python3-libgpiod
7. pip3 install --upgrade adafruit-blinka
8. python3
9. import board

This gives error:

I've tried forcing:

import os
os.environ["BLINKA_FORCEBOARD"] = "KHADAS_VIM3"
import board

I've tried this with both python3 and sudo python3

I managed to make this work, but it required modification of adafruit-blinka sourcecode, so I think there might be something wrong with it? I will give the details tomorrow.
