Hardware and Performance / I2C Interface
« 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
results always in an error:
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
