1 U-Boot for Amlogic W400
2 =======================
4 U200 is a reference board manufactured by Amlogic with the following
7 - Amlogic S922X ARM Cortex-A53 dual-core + Cortex-A73 quad-core SoC
9 - 10/100 Ethernet (Internal PHY)
19 Schematics are available from Amlogic on demand.
21 Currently the u-boot port supports the following devices:
30 > export CROSS_COMPILE=aarch64-none-elf-
37 Amlogic doesn't provide sources for the firmware and for tools needed
38 to create the bootloader image, so it is necessary to obtain them from
39 the git tree published by the board vendor:

52 Download the latest Amlogic Buildroot package, and extract it :
53 > wget http://openlinux2.amlogic.com:8000/ARM/filesystem/Linux_BSP/buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz
54 > tar xfz buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz buildroot_openlinux_kernel_4.9_fbdev_20180706/bootloader
55 > export BRDIR=$PWD/buildroot_openlinux_kernel_4.9_fbdev_20180706
56 > export FIPDIR=$BRDIR/bootloader/uboot-repo/fip
58 Go back to mainline U-Boot source tree then :
