- 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
