i tried the second one and dont want to go for first one. Earlier there were two I2C enable by default, but in this one there seems one.
Can someone please tell me the proper steps, if I want to enable I2c in my kernel "Linux arm 4.0.1-armv7-x2 ". These devices are present root@arm:/sys/bus/i2c/devices# ls -l i2c-* lrwxrwxrwx 1 root root 0 May 25 09:52 i2c-0 -> ../../../devices/platform/ocp/ 44e0b000.i2c/i2c-0 lrwxrwxrwx 1 root root 0 May 25 09:52 i2c-2 -> ../../../devices/platform/ocp/4819c000.i2c/i2c-2 but when i do sudo i2cdetect -l there is no output. Without degrading the kernel to 3.8, Any help to enable i2c would be appreciable. Regards :)) On Tuesday, 27 January 2015 22:19:43 UTC+5:30, Graham wrote: > > I think you have three choices: > > 1.)
