HCL:Orange Pi 2G-IoT
The Xunlong Orange Pi 2G-IoT is a single-board computer.
Technical data
- RDA 8810PL SoC
- 1x ARM Cortex-A5 CPU
- 256 MB RAM
- 40-pin connector
Manual installation
The baudrate of the debug UART is 921600. You may need to use a tool such as minicom or picocom rather than screen.
U-Boot
Mainline U-Boot does not yet contain support for this board or SoC.
git clone https://github.com/RDA8810/u-boot-RDA8810.git make rda8810_config make
You may want to tweak include/configs/rda_config_defaults.h.
dd if=u-boot.rda of=/dev/sdX bs=512 seek=256 iflag=fullblock oflag=direct
Kernel
The 4.12 kernel does not contain support for this board and SoC.
An initial patchset was submitted for 4.14. v1
For the vendor U-Boot you will need to append the .dtb:
cat arch/arm/boot/zImage arch/arm/boot/dts/rda8810pl-orangepi-2g-iot.dtb > zImage+dtb
From the U-Boot prompt, boot similar to this:
mux_config
setenv bootargs 'earlycon'
fatload mmc 0:1 ${kernel_addr} zImage+dtb
fatload mmc 0:1 ${script_addr} rda8810pl-orangepi-2g-iot.dtb
bootz ${kernel_addr} - ${script_addr}
