How to add custom LED on rock 5t using dts and rsetup?

DeepBlack · April 3, 2026, 2:10pm

According to Radxa documentation for Rock 5T i’ve tried to add new LED

GPIO3_C1(PIN11)(3.3V) <----> Resistor (select size according to LED datasheet) <----> LED positive <----> LED Negative <----> GND(PIN9)

Create new device tree overlay file

nano ~/user_led3.dts

/dts-v1/;
/plugin/;

#include <dt-bindings/gpio/gpio.h>
#include <dt-bindings/pinctrl/rockchip.h>

/ {
    fragment@0 {
        target-path = "/";                                      /* Primary dts node to be modified */
        __overlay__ {                                           /* Add or modify the contents of these brackets */
            custom-leds{                                        /* Add custom-leds node */
                compatible = "gpio-leds";
                status = "okay";
                microsd-led {                                   /* Add icrosd-led node */
                    gpios = <&gpio3 RK_PC1 GPIO_ACTIVE_HIGH>;   /* Register GPIO3_C1 as the enable pin of microsd-led, the enable is level-pull-high by default. */
                    linux,default-trigger = "mmc1";             /* Set default trigger to mmc1(SD Card) */
                };
            };
        };
    };
};

Load using rsetup → Overlays → Install 3rd party overlay
Then
sudo reboot

It will brick the board, OS can’t boot.
It looks like this piece of documentation is for a different board.

How to add the new led using the rsetup on Rock 5T?

Dear,

@RadxaYuntian @jack
Can you help with it?

After many attempts, I managed to get it to work using Merged DTB, but it will stop working after updating the system via rsetup, but I need a stable method using rsetup to make it work:

Your new merged dts is different from your original overlay. Have you tried to use the merged definition in the overlay?

Also the boot issue could be file access problem. Attach serial cable and see what the bootloader says.

The first variant i’ve posted is from radxa docks for rock 5t (Link here)
The second variant is mine.
I tried both options with rsetup.
Both options result in the device not working (failure to boot)

There should be some additional logs after android_image_load_by_partname: Can't find part: boot. Can you try recording the serial output with asciinema?

It wasn’t the DTS issue — it was that I was using a modified OS image, and in it the partition IDs were different from what rsetup expects. Everything is working fine now.

Thanks for your help!
