The Khadas vim2 derive from amlogic s912 reference design (Q200). This patch moves the khadas-vim2 board support to a generic Q200 board, while keeping a dedicated defconfig to customize the names and device tree. Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>

|
|
|
|
Q200 is a reference board manufactured by Amlogic with the following
|
|
specifications:
|
|
|
|
- Amlogic S912 ARM Cortex-A53 octo-core SoC @ 1.5GHz
|
|
- ARM Mali T860 GPU
|
|
- 2/3GB DDR4 SDRAM
|
|
- 10/100/1000 Ethernet
|
|

|
|
|
|
U-Boot compilation
|
|
==================
|
|
|
|
> export ARCH=arm
|
|
> export CROSS_COMPILE=aarch64-none-elf-
|
|
> make khadas-vim2_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:$PATH
|
|
> git clone https://github.com/BayLibre/u-boot.git -b n-amlogic-openlinux-20170606 amlogic-u-boot
|
|
> cd amlogic-u-boot
|
|
> make gxm_q200_v1_defconfig
|
|
> make
|
|
> export FIPDIR=$PWD/fip
|
|
|
|
Go back to mainline U-Boot source tree then :
|
|
> mkdir fip
|
|
|
|
> cp $FIPDIR/gxl/bl2.bin fip/
|
|
> cp $FIPDIR/gxl/acs.bin fip/
|
|
> cp $FIPDIR/gxl/bl21.bin fip/
|
|
> cp $FIPDIR/gxl/bl30.bin fip/
|
|
> cp $FIPDIR/gxl/bl301.bin fip/
|
|
> cp $FIPDIR/gxl/bl31.img fip/
|
|
> cp u-boot.bin fip/bl33.bin
|
|
|
|
> $FIPDIR/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
|
|
|
|
> python $FIPDIR/acs_tool.pyc fip/bl2.bin fip/bl2_acs.bin fip/acs.bin 0
|
|
|
|
> $FIPDIR/blx_fix.sh \
|
|
fip/bl2_acs.bin \
|
|
fip/zero_tmp \
|
|
fip/bl2_zero.bin \
|
|
fip/bl21.bin \
|
|
fip/bl21_zero.bin \
|
|
fip/bl2_new.bin \
|
|
bl2
|
|
|
|
> $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin
|
|
> $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl31.img
|
|
> $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl33.bin
|
|
> $FIPDIR/gxl/aml_encrypt_gxl --bl2sig --input fip/bl2_new.bin --output fip/bl2.n.bin.sig
|
|
> $FIPDIR/gxl/aml_encrypt_gxl --bootmk \
|
|
--output fip/u-boot.bin \
|
|
--bl2 fip/bl2.n.bin.sig \
|
|
--bl30 fip/bl30_new.bin.enc \
|
|
--bl31 fip/bl31.img.enc \
|
|
--bl33 fip/bl33.bin.enc
|
|
|
|
and then write the image to SD with:
|
|
|
|
> DEV=/dev/your_sd_device
|
|
> dd if=fip/u-boot.bin.sd.bin of=$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
