I've used Buildroot to build a minimal operative system. During the configuration step with the
menuconfig utility I specified to install I2C tools. The option was is
Target Package -> Hardware handling -> i2c-tools
But when I load the corresponding module I get the following error:
$sudo modprobe i2c-dev modprobe: module i2c-dev not found in modules.dep
Furthermore, the list in the
modules.dep file is empty.
$ cat /lib/modules/$(uname -r)/modules.dep $
I have probably missed something important.
Do I have to manually copy the kernel modules from the Buildroot installation folder to the target system? How to make the i2c tools working?
