Is there something I can do to test whether the i2c SMBus is at all
functional ?
Install i2c-tools [1] and try i2cdetect.
[1] http://www.lm-sensors.org/wiki/I2CTools
Ok, I included i2ctools as part of the OpenELEC build and this is now what
I get:
root ~ # ./i2cdetect -l
i2c-0 smbus SMBus I801 adapter at efa0 SMBus adapter
i2c-1 i2c Afatech AF9015 reference design I2C adapter
i2c-2 i2c NVIDIA i2c adapter 1 at 1:00.0 I2C adapter
i2c-3 i2c NVIDIA i2c adapter 2 at 1:00.0 I2C adapter
root ~ # ./i2cdetect -F 0
Functionalities implemented by /dev/i2c-0:
I2C no
SMBus Quick Command yes
SMBus Send Byte yes
SMBus Receive Byte yes
SMBus Write Byte yes
SMBus Read Byte yes
SMBus Write Word yes
SMBus Read Word yes
SMBus Process Call no
SMBus Block Write yes
SMBus Block Read yes
SMBus Block Process Call no
SMBus PEC yes
I2C Block Write yes
I2C Block Read yes
What's next ?
