The Anbernic RGxx3 is a "pseudo-device" that encompasses the following devices:
- Anbernic RG353M
- Anbernic RG353P
- Anbernic RG353V
- Anbernic RG353VS
- Anbernic RG503
The rk3566-anbernic-rgxx3.dtsi is synced with upstream Linux, but rk3566-anbernic-rgxx3.dts is a U-Boot specific devicetree that is used for all RGxx3 devices.
Via the board.c file, the bootloader automatically sets the correct fdtfile, board, and board_name environment variables so that the correct devicetree can be passed to Linux. It is also possible to simply hard-code a single devicetree in the boot.scr file and use that to load Linux as well.
The common specifications for each device are:
- Rockchip RK3566 SoC
- 2 external SDMMC slots
- 1 USB-C host port, 1 USB-C peripheral port
- 1 mini-HDMI output
- MIPI-DSI based display panel
- ADC controlled joysticks with a GPIO mux
- GPIO buttons
- A PWM controlled vibrator
- An ADC controlled button
All of the common features are defined in the devicetree synced from upstream Linux.
TODO: DSI panel auto-detection for the RG353 devices (requires porting of DSI controller driver and DSI-DPHY driver to send DSI commands to the panel).

+U-Boot for Anbernic RGxx3 Devices +=================================
+This allows U-Boot to boot the following Anbernic devices:
- Anbernic RG353M
- Anbernic RG353P
- Anbernic RG353V
- Anbernic RG353VS
- Anbernic RG503
+The correct device is detected automatically by comparing ADC values +from ADC channel 1. In the event of an RG353V, an attempt is then made +to probe for an eMMC and if it fails the device is assumed to be an +RG353VS. Based on the detected device, the environment variables +"board", "board_name", and "fdtfile" are set to the correct values +corresponding to the board which can be read by a boot script to boot +with the correct device tree.
+Please note that there are some versions of the RG353 devices with +different panels. Panel auto-detection is planned for a later date.
+Building U-Boot +---------------
+.. code-block:: bash
- $ export CROSS_COMPILE=aarch64-none-elf-
- $ export BL31=../rkbin/bin/rk35/rk3568_bl31_v1.34.elf
- $ export ROCKCHIP_TPL=../rkbin/bin/rk35/rk3568_ddr_1056MHz_v1.13.bin
- $ make anbernic-rgxx3_defconfig
- $ make
+This will build ``u-boot-rockchip.bin`` which can be written to an SD +card.
+Image installation +------------------
+Write the ``u-boot-rockchip.bin`` to an SD card offset 32kb from the +start.
+.. code-block:: bash
- $ dd if=u-boot-rockchip.bin of=/dev/mmcblk0 bs=512 seek=64
