4 Khadas VIM is an Open Source DIY Box manufactured by Shenzhen Wesion
5 Technology Co., Ltd with the following specifications:
7 - Amlogic S905X ARM Cortex-A53 quad-core SoC @ 1.5GHz
11 - HDMI 2.0 4K/60Hz display
13 - 2 x USB 2.0 Host, 1 x USB 2.0 Type-C OTG
16 - SDIO Wifi Module, Bluetooth
17 - Two channels IR receiver
19 Currently the u-boot port supports the following devices:
34 > export CROSS_COMPILE=aarch64-none-elf-
35 > make khadas-vim_defconfig
41 Amlogic doesn't provide sources for the firmware and for tools needed
42 to create the bootloader image, so it is necessary to obtain them from
43 the git tree published by the board vendor:
45 > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
46 > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
47 > tar xvfJ gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
48 > tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
49 > 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:$PATH
50 > git clone https://github.com/khadas/u-boot -b Vim vim-u-boot
53 > make CROSS_COMPILE=aarch64-none-elf-
54 > export FIPDIR=$PWD/fip
56 Go back to mainline U-Boot source tree then :
59 > cp $FIPDIR/gxl/bl2.bin fip/
60 > cp $FIPDIR/gxl/acs.bin fip/
61 > cp $FIPDIR/gxl/bl21.bin fip/
62 > cp $FIPDIR/gxl/bl30.bin fip/
63 > cp $FIPDIR/gxl/bl301.bin fip/
64 > cp $FIPDIR/gxl/bl31.img fip/
65 > cp u-boot.bin fip/bl33.bin
67 > $FIPDIR/blx_fix.sh \
76 > python $FIPDIR/acs_tool.pyc fip/bl2.bin fip/bl2_acs.bin fip/acs.bin 0
78 > $FIPDIR/blx_fix.sh \
87 > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin
88 > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl31.img
89 > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl33.bin
90 > $FIPDIR/gxl/aml_encrypt_gxl --bl2sig --input fip/bl2_new.bin --output fip/bl2.n.bin.sig
91 > $FIPDIR/gxl/aml_encrypt_gxl --bootmk \
92 --output fip/u-boot.bin \
93 --bl2 fip/bl2.n.bin.sig \
94 --bl30 fip/bl30_new.bin.enc \
95 --bl31 fip/bl31.img.enc \
96 --bl33 fip/bl33.bin.enc
98 and then write the image to SD with:
100 > DEV=/dev/your_sd_device
101 > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
102 > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444
