U-Boot Compilation
|
|
------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ export CROSS_COMPILE=aarch64-none-elf-
|
|
$ make p201_defconfig
|
|
$ make
|
|
|
|
U-Boot Signing with Pre-Built FIP repo
|
|
--------------------------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ git clone https://github.com/LibreELEC/amlogic-boot-fip --depth=1
|
|
$ cd amlogic-boot-fip
|
|
$ mkdir my-output-dir
|
|
$ ./build-fip.sh p201 /path/to/u-boot/u-boot.bin my-output-dir
|

|
U-Boot Manual Signing
|
|
---------------------
|
|
|
|
Amlogic does not provide sources for the firmware and tools needed to create a bootloader
|
|
image but sources have been shared by Linux development contractor, Baylibre:
|
|
|
|
.. 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 gxb_p201_v1_defconfig
|
|
$ make
|
|
$ export FIPDIR=$PWD/fip
|
|
|
|
Go back to mainline U-Boot source tree then :
|
|
|
|
.. code-block:: bash
|
|
|
|
$ mkdir fip
|
|
|
|
$ cp $FIPDIR/gxb/bl2.bin fip/
|
|
$ cp $FIPDIR/gxb/acs.bin fip/
|
|
$ cp $FIPDIR/gxb/bl21.bin fip/
|
|
$ cp $FIPDIR/gxb/bl30.bin fip/
|
|
$ cp $FIPDIR/gxb/bl301.bin fip/
|
|
$ cp $FIPDIR/gxb/bl31.img fip/
|
|
$ cp u-boot.bin fip/bl33.bin
|
|
$ wget https://github.com/LibreELEC/amlogic-boot-fip/raw/master/nanopi-k2/bl1.bin.hardkernel fip/bl1.bin.hardkernel
|
|
$ chmod +x fip/bl1.bin.hardkernel
|
|
$ wget https://github.com/LibreELEC/amlogic-boot-fip/raw/master/nanopi-k2/aml_chksum fip/aml_chksum
|
|
$ chmod +x fip/aml_chksum
|
|
|
|
$ $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/fip_create --bl30 fip/bl30_new.bin \
|
|
--bl31 fip/bl31.img \
|
|
--bl33 fip/bl33.bin \
|
|
fip/fip.bin
|
|
|
|
$ cat fip/bl2_new.bin fip/fip.bin >fip/boot_new.bin
|
|
|
|
$ $FIPDIR/gxb/aml_encrypt_gxb --bootsig \
|
|
--input fip/boot_new.bin \
|
|
--output fip/u-boot.bin
|
|
|
|
Then write U-Boot to SD or eMMC with:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ DEV=/dev/boot_device
|
|
$ dd if=fip/u-boot.bin of=fip/u-boot.bin.gxbb bs=512 conv=fsync
|
|
$ dd if=fip/u-boot.bin of=fip/u-boot.bin.gxbb bs=512 seek=9 skip=8 count=87 conv=fsync,notrunc
|
|
$ dd if=/dev/zero of=fip/u-boot.bin.gxbb bs=512 seek=8 count=1 conv=fsync,notrunc
|
|
$ dd if=bl1.bin.hardkernel of=fip/u-boot.bin.gxbb bs=512 seek=2 skip=2 count=1 conv=fsync,notrunc
|
|
$ ./aml_chksum fip/u-boot.bin.gxbb
|
|
$ dd if=fip/u-boot.gxbb of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
|
|
$ dd if=fip/u-boot.gxbb of=$DEV conv=fsync,notrunc bs=1 count=440
