Hello Simran,

In Reloading Modules I tried the first command it works fine for me.

git/kernels/staging$ ls drivers/iio/dummy/*.ko
drivers/iio/dummy/iio_dummy_evgen.ko  drivers/iio/dummy/iio_dummy.ko

Then I tried to run second-command

git/kernels/staging$ sudo modprobe -r iio_dummy_evgen

I got the following error:-
modprobe: FATAL: Module iio_dummy_evgen not found.

  Maybe as iio_dummy_evgen is not loaded it causes this error.

I am not getting what is wrong with this.

You need to execute commands in following order

make drivers/iio/dummy/iio_dummy_evgen.ko
make drivers/iio/dummy/iio_dummy.ko

sudo modprobe iio_dummy_evgen
sudo modprobe iio_dummy

Check if they are loaded successfully with lsmod | grep "iio".

Thanks,

This is also not working. I am getting this error now:
modprobe: FATAL: Module iio_dummy_evgen not found in directory
/lib/modules/4.10.0-rc3+

I am basically trying to do the Task1 of IIO. Here is the link:-
https://kernelnewbies.org/IIO_tasks

In this task they have asked to use this:
$ insmod iio_dummy_evgen.ko

As this was not working, so I tried modprobe.

Thanks!
Simran
