Hello,
I am running Centos on a raspberry pi 2b. (I downloaded the image from: http://people.centos.org/hughesjr/armv7hl/rpi2/images/ rpi2-centos-image.img.xz ) and installed the i2c libraries and modules for i2c. [root@rpi2-2 ~]# lsmod | grep i2c
i2c_bcm2708 5006 0 i2c_dev 6027 0
From what I read that should be correct
device file is there too: crw------- 1 root root 89, 1 Dec 31 1969 i2c-1
kernel: Linux rpi2-2 3.18.14-v7+ #794 SMP PREEMPT Sun Jun 7 12:50:51 BST 2015 armv7l armv7l armv7l GNU/Linux
However, when I scan the i2c bus with 'i2cdetect -y 1' I don't see any devices (and I tried 2 that I know work).
is the I2C stuff in this kernel working? (or is there a newer kernel version?)
thanks,
Ron
P.S. I know this is an arm-dev list, but figured the I2C topic would fit better here than in a general Centos list
