1 U-Boot for Amlogic SEI610
2 =========================
4 SEI610 is a customer board manufactured by SEI Robotics with the following
7 - Amlogic S905X3 ARM Cortex-A55 quad-core SoC
9 - 10/100 Ethernet (Internal PHY)
12 - 1 x FTDI USB Serial Debug Interface
22 > export CROSS_COMPILE=aarch64-none-elf-
23 > make sei610_defconfig
29 Amlogic doesn't provide sources for the firmware and for tools needed
30 to create the bootloader image, so it is necessary to obtain them from
31 the git tree published by the board vendor:

38 > git clone https://github.com/BayLibre/u-boot.git -b buildroot-openlinux-4.9-g12a-201904 amlogic-u-boot
40 > make sm1_ac200_v1_defconfig
42 > export UBOOTDIR=$PWD
44 Download the latest Amlogic Buildroot package, and extract it :
45 > wget http://openlinux2.amlogic.com:8000/ARM/filesystem/buildroot-openlinux-A113-201901.tgz
46 > tar xfz buildroot-openlinux-A113-201901.tgz buildroot-openlinux-A113-201901/bootloader
47 > export BRDIR=$PWD/buildroot-openlinux-A113-201901
48 > export FIPDIR=$BRDIR/bootloader/uboot-repo/fip
50 Go back to mainline U-Boot source tree then :
