I am trying the dummy-iiostream.c script from this repo. Few commands were mentioned at beginning of the script to execute. I mentioned them below :

  1. sudo modprobe industrialio
  2. sudo modprobe industrialio-configfs
  3. sudo modprobe industrialio-sw-device
  4. sudo modprobe industrialio-sw-trigger
  5. sudo modprobe iio-trig-hrtimer
  6. sudo modprobe iio_dummy

I am facing problem executing the 3rd command , here is my console output

rohith@raspberrypi:~ $ sudo modprobe industrialio
rohith@raspberrypi:~ $ sudo modprobe industrialio-configfs
rohith@raspberrypi:~ $ sudo modprobe industrialio-sw-device
modprobe: FATAL: Module industrialio-sw-device not found in directory /lib/modules/5.15.56-v8+
rohith@raspberrypi:~ $

How do I resolve this error? I am new to Linux any help would be greatly appreciated. My aim is to successfully execute all the 6 commands and run the script.

Did you successfully run the other steps in the source file?

Are you positive, that the first modules are loaded properly? (lsmod | grep -i industrialio)

Also, loadable modules have to be in the right folder. Looks like thats "/lib/modules/5.15.56-v8+" for you. Check if all needed files are present here.
