I2C doesn't seem to work after reboot

#1

Hi! I’m trying to enable I2C7 bus on a ROCK 4 SE. I enabled the interface through the rsetup tool and reboot. However, I can’t see /dev/i2c-7. Any solutions?
Thanks

#2

did you use sudo as part of your i2cdetect? there is no default user access. pet peave about that here.

Hi! Even using sudo I can’t see /dev/i2c-7 device activated when I type ls -l /dev/.
