Hi,
I've added the following parameters to /boot/cmdline.txt
i2c_arm=on i2c1=on i2c0=on
but I get no /dev/i2c* entries, but dmesg shows
i2c /dev entries driver
What am I missing ?
Thanks
Phil

We need a little more info, right now I can think of 1) which device? 2) which CentOS version? 3) if it is a raspberry pi, generic kernel or rpi kernel?

yeah, one needs to enable a thing or 2-3 in a boot config file on an image.
This one here is the guide for an Ubuntu version, but I run centos on several raspberry pi boards, and seeems to work.

Hi all,
thanks for the replies, yes I was putting the entries in cmdline.txt and not config.txt, once I corrected this everything was good.
Thanks again for your help.
