You say you understand it is read only, but this error message is
exactly the problem you are having. You cannot change things in a
directory which is on a read-only filesystem.
It appears you do not have the devtmpfs built into your kernel (the one
which comes pre-populated with lots of helpful device nodes), so you
will need to use something else, like tmpfs (which comes completely
empty, but writable).
Maybe try
mount -t tmpfs none /dev
mknod -m 666 /dev/null c 1 3
# and all the rest of your device nodes
