Write adb shell and then just write su.

Do you have root installed?
S.

Normally Android asks permission for host to (always) connect.
Next SuperSU asks to grant root access
(maybe you need to clear SuperSU table if once denied or timed out).
I have not tried M only N. And only kvim2.

Perhaps also try:
su - root
success.

i am sorry, what do you mean by " root installed"?

so you mean :
step 1: adb shell
step 2: su - root ??
but only do this , not work,
(khadas + android M)

Maybe you should try:
step 1: adb root
step 2: adb shell

Have you flashed supersu?
