4 Khadas VIM2 is an Open Source DIY Box manufactured by Shenzhen Wesion
5 Technology Co., Ltd with the following specifications:
7 - Amlogic S912 ARM Cortex-A53 octo-core SoC @ 1.5GHz
10 - 10/100/1000 Ethernet
11 - HDMI 2.0 4K/60Hz display
13 - 2 x USB 2.0 Host, 1 x USB 2.0 Type-C OTG
17 - SDIO Wifi Module, Bluetooth
18 - Two channels IR receiver
20 Currently the u-boot port supports the following devices:
35 > export CROSS_COMPILE=aarch64-none-elf-
36 > make khadas-vim2_defconfig
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:
46 > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
47 > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz

49 > tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
50 > 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:$PATH
51 > git clone https://github.com/khadas/u-boot -b khadas-vim-v2015.01 vim-u-boot
53 > make kvim2_defconfig
55 > export FIPDIR=$PWD/fip
57 Go back to mainline U-Boot source tree then :
60 > cp $FIPDIR/gxl/bl2.bin fip/
61 > cp $FIPDIR/gxl/acs.bin fip/
62 > cp $FIPDIR/gxl/bl21.bin fip/
63 > cp $FIPDIR/gxl/bl30.bin fip/
64 > cp $FIPDIR/gxl/bl301.bin fip/
65 > cp $FIPDIR/gxl/bl31.img fip/
66 > cp u-boot.bin fip/bl33.bin
68 > $FIPDIR/blx_fix.sh \
77 > python $FIPDIR/acs_tool.pyc fip/bl2.bin fip/bl2_acs.bin fip/acs.bin 0
79 > $FIPDIR/blx_fix.sh \
88 > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin
89 > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl31.img
90 > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl33.bin
91 > $FIPDIR/gxl/aml_encrypt_gxl --bl2sig --input fip/bl2_new.bin --output fip/bl2.n.bin.sig
92 > $FIPDIR/gxl/aml_encrypt_gxl --bootmk \
93 --output fip/u-boot.bin \
94 --bl2 fip/bl2.n.bin.sig \
95 --bl30 fip/bl30_new.bin.enc \
96 --bl31 fip/bl31.img.enc \
97 --bl33 fip/bl33.bin.enc
99 and then write the image to SD with:
101 > DEV=/dev/your_sd_device
102 > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
103 > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444
