U-Boot for WeTek Core2
|
|
======================
|
|
|
|
WeTek Core2 is an Android STB based on the Q200 reference design with
|
|
the following specifications:
|
|
|
|
- Amlogic S912 ARM Cortex-A53 octo-core SoC @ 1.5GHz
|
|
- ARM Mali T820 GPU
|
|
- 3GB DDR4 SDRAM
|
|
- 10/100 Realtek RTL8152 Ethernet (internal USB)
|
|
- HDMI 2.0 4K/60Hz display
|
|
- 2x USB 2.0 Host, 1x USB 2.0 OTG (internal)
|
|
- 32GB eMMC
|
|
- microSD
|
|
- SDIO Wifi Module, Bluetooth
|
|
- Two channel IR receiver
|
|
|
|
U-Boot compilation
|
|
------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ export CROSS_COMPILE=aarch64-none-elf-
|
|
$ make wetek-core2_defconfig
|
|
$ make
|
|
|
|
Image creation
|
|
--------------
|
|
|
|
Amlogic does not provide sources for the firmware or the tools needed
|
|
to create the bootloader image, and WeTek has not publicly shared the
|
|
precompiled FIP binaries. However the public Khadas VIM2 sources also
|
|
work with the Core2 box so we can use the Khadas git tree:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ 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/khadas/u-boot -b khadas-vim-v2015.01 vim-u-boot
|
|
$ cd vim-u-boot
|
|
$ make kvim2_defconfig
|
|
$ make
|
|
$ export FIPDIR=$PWD/fip
|
|
|
|
Go back to mainline U-Boot source tree then:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ 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
|
|
|
|
then write the image to SD with:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ 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
|
