=== Device Tree Overlays===

====Introduction====

This directory contains Device Tree overlays. Device Tree makes it possible
to support many hardware configurations with a single kernel and without the
need to explicitly load or blacklisr kernel modules.

On Radxa borad which uses linux5.10 kernel, you can use "rsetup" to load overlays that you want to enable, rsetup load overlays' dtbo from [[https://github.com/radxa/overlays/tree/main/arch/arm64/boot/dts/rockchip/overlays Radxa/overlay]]

===== How to enable a overlay dtbo =====

run "rsetup" command as below:
radxa@rock-4c-plus:~$ rsetup

Select the overlays you want to load with the space bar,

[*] rk3399-uart0.dtbo

Overlay with a "*" indicates that it is enabled.

===== How to use a overylay written by yourselt =====

Because of the number of products we have, writing the device tree overlay(dtbo) for each product has become a significant burden. To improve code reuse, you now need to specify metadata for dtbo to facilitate sharing of the same dtbo across different products
