Succeeded to build the ethos-n-stack driver. I succeeded to build it using this page:
The build generates some files, one of them is the driver .ko file (ethosn.ko). I should install this driver using the command "sudo insmod ethos.ko". But when I run this command, I got this error.

Notice that I extract this error message using the command "dmesg | tail -n 20".
Would any one please explain what is the meaning of this error and how can I debug it?
I think there is a typo and your command should "insmod ethosn.ko"

If it still failing then please let me know the Linux kernel version and platform setup you're using to test the ethos-n kernel-module
Thank you for your reply.Actually this was a typo while writing the question. I am using the correct file name "ethosn.ko" When I run the command.After much debugging, I found the reason for the issue. I will post it as a reply to my original question.Thank you,
