Hi all, I'm new to armbian, I have a nanopi r4s SBC, and I want to know that if armbian nanopi r4s enabled(applied) `overlays-00-add-oc-opp-rk3399.patch` by default?

 

i.e. https://github.com/armbian/build/blob/master/patch/kernel/archive/rockchip64-5.10/overlays-00-add-oc-opp-rk3399.patch

 

I really need this patch to bootst up performance, otherwise I have to build armbian by myself.

OC is not enabled by default but you can simply enable is via armbian-config.

I've check the DT, the overclock patch hasn't applied to the kernel DT. it using the default clock, and in armbian-config, the maximum clock speed allowable is 1.8GHz.

 

```

        opp07 {
            opp-hz = <0x00 0x6b49d200>;
            opp-microvolt = <0x124f80>;
        };
```

Hm odd. It seems like overlay support is completely gone or I am blind...

I didn't know it could be done with armbian-config. I always did it manually in /boot/armbianEnv.txt
 

overlay_prefix=rockchip
overlays=rk3399-opp-2ghz

That is how I always did that...

Thanks you guys! @Werner, @NicoD

 

Here is how I did this:

 

```

$ sudo armbian-add-overlay rk3399-oc.dts

 

$ ls -1 /boot/overlay-user/

rk3399-oc.dtbo

 

$ cat /boot/armbianEnv.txt

verbosity=1

bootlogo=false

overlay_prefix=rockchip

rootdev=UUID=6c8153dd-e3ae-4b9c-8ea2-9c34a84bbed8

rootfstype=ext4

console=serial

usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u

user_overlays=rk3399-oc

 

$ reboot

$ sudo apt install -y armbian-config

$ sudo armbian-config # System -> CPU (Choose new CPU freq)

 

# Done

```
