I2C Interface

[FW1000]

Hello!

I am wondering whether it is possible to access the I2C interface of a mainboard with OPNsense (19.7).

Tried to load the kernel modules smbus and iic (and much more). But scanning the I2C interface with

Code Select Expand

i2c -f /dev/iic0 -s

results always in an error:

Code Select Expand

Error opening I2C controller (/dev/iic0) for scanning: No such file or directory

dmesg shows nothing about i2c (iic), etc. Nothing about loading the modules.

With Linux (Debian, CentOS, ...) it is possible to access the I2C interface of the mainboard.

What do I miss? Appreciate any comment, link ...

Thanks

Resurrecting an old topic. I'm trying to control the fan on an Edge 640 and need the I2C command to accomplish this. I can load the iicbus and iic modules, but no /dev/iicX devices are created. Anyone ever get this to work?
