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
