I2C controller on PC engines APU2C4
-
How to make the controller work?
It should work on FreeBSD(I think)
If a run dmesg it doest not show up.
Can I fix this somehow? -

I am gonna connect a lcd to it and the lcdproq supports i2c.
What should i look for in dmesg?
Can you show me how it is suppose to look?
Maybe I installed nano version or something, gonna reinstall pfsense and see.
I get back after that

I reinstalled pfsense 2.4.2 now just in case.
have APU2C4 and latest compiled bios I can find which is 4.0.12 (the 4.6 version is not stable on my card).
If i take a Shell and enter: "dmesg | grep iic" I get Nothing. Shouldnt my i2c bus show up there?
-
How does ur dmesg screen look like?
What i have research it should show up there.
I just installed latest freebsd 11.1(?) just to see if it shows up but it Doesnt.
There are commands available in freebsd to test the bus and so on.I hope somebody knowing what they are talking about see this thread and shine some light on it.

It seems like you might need to load a driver if you want to use the existing tools, rather than talking to the device directly.
