- 2 x USB 2.0 Host, 1 x USB 2.0 Device
- 16GB/32GB/64GB eMMC
- 2MB SPI Flash
- microSD
- SDIO Wifi Module, Bluetooth
- IR receiver
U-Boot compilation
------------------
.. code-block:: bash
$ 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:
.. 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/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 :
.. 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
and 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
