1 U-Boot for Amlogic S400
2 =======================
4 S400 is a reference board manufactured by Amlogic with the following
7 - Amlogic A113DX ARM Cortex-A53 quad-core SoC @ 1.2GHz
16 - PCI-E M.2 Connectors
18 Schematics are available from Amlogic on demand.
20 Currently the u-boot port supports the following devices:
35 > export CROSS_COMPILE=aarch64-none-elf-
42 Amlogic doesn't provide sources for the firmware and for tools needed
43 to create the bootloader image, so it is necessary to obtain them from
44 the git tree published by the board vendor:

57 Go back to mainline U-boot source tree then :
60 > cp $FIPDIR/axg/bl2.bin fip/
61 > cp $FIPDIR/axg/acs.bin fip/
62 > cp $FIPDIR/axg/bl21.bin fip/
