Error running install command for unipi_eprom when booting stretch

juntiedt

Hi Tomas,

I get this error above mentioned message when booting stretch after the installation of evok.
it seems to be a problem with eprom of unipi.

system Status:

How can I fix it?

@juntiedt It seems that I2C is not enabled. Could you post content of /boot/config.txt and /etc/modules and the output of lsmod command? Btw. did you restart UniPi after installation?

Hi Tomas,
hope you meant command insmod.

If I2C works, then the errors should be harmless. The modules are used for older versions of Raspbian, and as a whole don't indicate that anything is wrong by itself.

You can delete the 4 lines in /etc/modules to stop the error from cropping up.

We'll try to do it with kernel version detection during the installation, or drop the old versions altogether.

Edit: The insmod fails because the modules are compiled for an older kernel, and will only load on old Jessie
