Install Overlays

Install 3rd party overlay

Device Tree Overlays make it possible to support many hardware configurations with a single kernel and without the need to explicitly load or blacklist kernel modules.

You can use rsetup to manage overlays.

info

The Install 3rd party overlay feature of rsetup installs both device tree overlay files (DTBO) and source code (DTS).

Pre-compiled files from the official DTBO repository radxa/overlays can be downloaded from here.

Get radxa/overlays source code

git clone https://github.com/radxa/overlays.git
cd overlays

Load the overlay using rsetup

Select Overlays in rsetup's main interface:

Configure Device Tree Overlay
        Manage overlays
        View overlay info
        Install 3rd party overlay"
        Reset overlays
        <Ok>             <Cancel>

Then, select Install 3rd party overlay:

Configure Device Tree Overlay
        Manage overlays
        View overlay info
        Install 3rd party overlay
        Reset overlays


      <Ok>            <Cancel>

info

The following is the path to the source code of the Rexchip SOC device tree overlay file.

arch/arm64/boot/dts/rockchip/overlays/*.dts

If the SOC vendor is Amlogic, you need to replace rockchip with amlogic in the above path.

Then select the overlay you want to load, then exit rsetup, and finally reboot.

tip

You can check the parameters using cat /boot/extlinux/extlinux.conf
