| U-Boot for ODROID-N2
 | |
| ====================
 | |
| 
 | |
| ODROID-N2 is a single board computer manufactured by Hardkernel
 | |
| Co. Ltd with the following specifications:
 | |
| 
 | |
|  - Amlogic S922X ARM Cortex-A53 dual-core + Cortex-A73 quad-core SoC
 | |
|  - 4GB DDR4 SDRAM
 | |
|  - Gigabit Ethernet
 | |
|  - HDMI 2.1 4K/60Hz display
 | |
|  - 40-pin GPIO header
 | |
|  - 4 x USB 3.0 Host, 1 x USB OTG
 | |
|  - eMMC, microSD
 | |
|  - Infrared receiver
 | |
| 
 | |
| Schematics are available on the manufacturer website.
 | |
| 
 | |
| Currently the u-boot port supports the following devices:
 | |
|  - serial
 | |
|  - eMMC, microSD
 | |
|  - Ethernet
 | |
|  - I2C
 | |
|  - Regulators
 | |
|  - Reset controller
 | |
|  - Clock controller
 | |
|  - ADC
 | |
| 
 | |
| u-boot compilation
 | |
| ==================
 | |
| 
 | |
|  > export ARCH=arm
 | |
|  > export CROSS_COMPILE=aarch64-none-elf-
 | |
|  > make odroid-n2_defconfig
 | |
|  > make
 | |
| 
 | |
| Image creation
 | |
| ==============
 | |
| 
 | |
| Amlogic doesn't provide sources for the firmware and for tools needed
 | |
| to create the bootloader image, so it is necessary to obtain them from
 | |
| the git tree published by the board vendor:
 | |
| 
 | |

|  > DIR=odroid-n2
 | |
|  > git clone --depth 1 \
