I have try to add the overlay but i think Is for 5.10 kernel...I'm not very experienced so I don't know how I could do it https://github.com/radxa/kernel/blob/linux-5.10-gen-rkr3.4/arch/arm64/boot/dts/rockchip/overlay/rock-4c-plus-raspi-7inch-touchscreen.dts

Could anyone help me to enable display with Armbian? I just can’t figure out why it doesn’t work. I don’t see the backlight turning on either. What do I have to change? I have tru to add a custom dts on kernel but don't work
