4 ODROID-N2 is a single board computer manufactured by Hardkernel
5 Co. Ltd with the following specifications:
7 - Amlogic S922X ARM Cortex-A53 dual-core + Cortex-A73 quad-core SoC
10 - HDMI 2.1 4K/60Hz display
12 - 4 x USB 3.0 Host, 1 x USB OTG
16 Schematics are available on the manufacturer website.
18 Currently the u-boot port supports the following devices:
31 > export CROSS_COMPILE=aarch64-none-elf-
32 > make odroid-n2_defconfig
38 Amlogic doesn't provide sources for the firmware and for tools needed
39 to create the bootloader image, so it is necessary to obtain them from
40 the git tree published by the board vendor:
