How to copy .ko file to modules

1

I want to copy .ko file to “/lib/modules//extra” but it’s error: Read file only

can you suggest me how to copy .ko file to “wp76” module

Here is an example to make /usr/bin to be writable:

mkdir /tmp/tmp_usr_bin/;
mkdir /tmp/tmp_usr_bin_wr;
mount -t overlay overlay /usr/bin -o lowerdir=/usr/bin,upperdir=/tmp/tmp_usr_bin,workdir=/tmp/tmp_usr_bin_wr;

Maybe you can try to same.

you missed the “/” character before “lib”
