U-Boot for Amlogic W400 ======================= U200 is a reference board manufactured by Amlogic with the following specifications: - Amlogic S922X ARM Cortex-A53 dual-core + Cortex-A73 quad-core SoC - 2GB DDR4 SDRAM - 10/100 Ethernet (Internal PHY) - 1 x USB 3.0 Host - eMMC - SDcard - Infrared receiver - SDIO WiFi Module - MIPI DSI Connector - Audio HAT Connector - PCI-E M.2 Connector Schematics are available from Amlogic on demand. Currently the u-boot port supports the following devices: - serial - Ethernet - Regulators - Clock controller u-boot compilation ================== > export ARCH=arm > export CROSS_COMPILE=aarch64-none-elf- > make w400_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: > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz > tar xvfJ gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz > tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz > export PATH=$PWD/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux/bin:$PWD/gcc-linaro-arm-none-eabi-4.8-2013.11_linux/bin:$PATH > git clone https://github.com/BayLibre/u-boot.git -b buildroot-openlinux-20180418 amlogic-u-boot > cd amlogic-u-boot > make g12b_w400_v1_defconfig > make > export UBOOTDIR=$PWD Download the latest Amlogic Buildroot package, and extract it : > wget http://openlinux2.amlogic.com:8000/ARM/filesystem/Linux_BSP/buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz > tar xfz buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz buildroot_openlinux_kernel_4.9_fbdev_20180706/bootloader > export BRDIR=$PWD/buildroot_openlinux_kernel_4.9_fbdev_20180706 > export FIPDIR=$BRDIR/bootloader/uboot-repo/fip Go back to mainline U-Boot source tree then : > mkdir fip > wget https://github.com/BayLibre/u-boot/releases/download/v2017.11-libretech-cc/blx_fix_g12a.sh -O fip/blx_fix.sh > cp $UBOOTDIR/build/scp_task/bl301.bin fip/ > cp $UBOOTDIR/build/board/amlogic/g12b_w400_v1/firmware/acs.bin fip/ > cp $BRDIR/bootloader/uboot-repo/bl2/bin/g12b/bl2.bin fip/ > cp $BRDIR/bootloader/uboot-repo/bl30/bin/g12b/bl30.bin fip/ > cp $BRDIR/bootloader/uboot-repo/bl31_1.3/bin/g12b/bl31.img fip/ > cp $FIPDIR/g12b/ddr3_1d.fw fip/ > cp $FIPDIR/g12b/ddr4_1d.fw fip/ > cp $FIPDIR/g12b/ddr4_2d.fw fip/ > cp $FIPDIR/g12b/diag_lpddr4.fw fip/ > cp $FIPDIR/g12b/lpddr4_1d.fw fip/ > cp $FIPDIR/g12b/lpddr4_2d.fw fip/ > cp $FIPDIR/g12b/piei.fw fip/ > cp $FIPDIR/g12b/aml_ddr.fw fip/ > cp u-boot.bin fip/bl33.bin > sh fip/blx_fix.sh \ fip/bl30.bin \ fip/zero_tmp \ fip/bl30_zero.bin \ fip/bl301.bin \ fip/bl301_zero.bin \ fip/bl30_new.bin \ bl30 > sh fip/blx_fix.sh \ fip/bl2.bin \ fip/zero_tmp \ fip/bl2_zero.bin \ fip/acs.bin \ fip/bl21_zero.bin \ fip/bl2_new.bin \ bl2 > $FIPDIR/g12b/aml_encrypt_g12b --bl30sig --input fip/bl30_new.bin \ --output fip/bl30_new.bin.g12a.enc \ --level v3 > $FIPDIR/g12b/aml_encrypt_g12b --bl3sig --input fip/bl30_new.bin.g12a.enc \ --output fip/bl30_new.bin.enc \ --level v3 --type bl30 > $FIPDIR/g12b/aml_encrypt_g12b --bl3sig --input fip/bl31.img \ --output fip/bl31.img.enc \ --level v3 --type bl31 > $FIPDIR/g12b/aml_encrypt_g12b --bl3sig --input fip/bl33.bin --compress lz4 \ --output fip/bl33.bin.enc \ --level v3 --type bl33 > $FIPDIR/g12b/aml_encrypt_g12b --bl2sig --input fip/bl2_new.bin \ --output fip/bl2.n.bin.sig > $FIPDIR/g12b/aml_encrypt_g12b --bootmk \ --output fip/u-boot.bin \ --bl2 fip/bl2.n.bin.sig \ --bl30 fip/bl30_new.bin.enc \ --bl31 fip/bl31.img.enc \ --bl33 fip/bl33.bin.enc \ --ddrfw1 fip/ddr4_1d.fw \ --ddrfw2 fip/ddr4_2d.fw \ --ddrfw3 fip/ddr3_1d.fw \ --ddrfw4 fip/piei.fw \ --ddrfw5 fip/lpddr4_1d.fw \ --ddrfw6 fip/lpddr4_2d.fw \ --ddrfw7 fip/diag_lpddr4.fw \ --ddrfw8 fip/aml_ddr.fw \ --level v3 and then write the image to SD with: > DEV=/dev/your_sd_device > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1 > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444
