Title: I2C Interface
Post by: FW1000 on July 24, 2019, 01:17:16 pm

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]

i2c -f /dev/iic0 -s

results always in an error:

Code: [Select]

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
