Evok do not read device configuration

christophebler

Hi !
We Are using a UniPi Neuron S103. We have upgraded our EVOK installation to the version 2.4. First We Uninstalled the old version ant afterword’s installed the new version.

If we open the UniPi Control panel there is No Device configuration loaded.

We also tried to start evok manual using :

sudo systemctl stop evok.service
sudo python /opt/evok/evok.py

this results in the Following Error message

[I 180131 10:36:52 config:78] YAML Definition loaded: L51x.yaml, type: 3, definition count 14

[I 180131 10:36:53 neuron:575] PLEASE USE A FRESH EVOK IMAGE, OR ENABLE I2C, I2C-DEV AND THE EEPROM OVERLAY

Dou you have any idea what is going on there ? Do I have a wrong firmware version ?

Thanks for your help

@christophebler How did you update to evok 2.4? This version does not exist.

Check the last two lines from the log you provided. It says that I2C is not enabled so either enable it or use a fresh UniPian or Raspbian image.

Thank you for your fast Response.

I think the version number 2.4 was a misunderstanding. I was talking about Config version 2.4. my fault.

I have solved this problem by installing a new OS Raspbian Stretch 2017-11-29. And afterword’s installed all my needed Software.

Now everything works as designed

Thank you

Christoph
