|
|
====================
|
|
|
|
NanoPi-K2 is a single board computer manufactured by FriendlyElec
|
|
with the following specifications:
|
|
|
|

|
|
- ARM Mali 450 GPU
|
|
- 2GB DDR3 SDRAM
|
|
- Gigabit Ethernet
|
|
- HDMI 2.0 4K/60Hz display
|
|
- 40-pin GPIO header
|
|
- 4 x USB 2.0 Host, 1 x USB OTG
|
|

U-Boot compilation
|
|
------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ export CROSS_COMPILE=aarch64-none-elf-
|
|
$ make nanopi-k2_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 libretech-cc amlogic-u-boot
|
|
$ git clone https://github.com/friendlyarm/u-boot.git -b nanopi-k2-v2015.01 amlogic-u-boot
|
|
$ cd amlogic-u-boot
|
|
$ sed -i 's/aarch64-linux-gnu-/aarch64-none-elf-/' Makefile
|
|
$ sed -i 's/arm-linux-/arm-none-eabi-/' arch/arm/cpu/armv8/gxb/firmware/scp_task/Makefile
|
|
$ make nanopi-k2_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
|
|
|
|
$ $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
|
|
|
|
$ $FIPDIR/fip_create \
|
|
--bl30 fip/bl30_new.bin \
|
|
--bl31 fip/bl31.img \
|
|
--bl33 fip/bl33.bin \
|
|
fip/fip.bin
|
|
|
|
$ 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
|
|
|
|
$ 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
|
|
|
|
and then write the image to SD with:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ DEV=/dev/your_sd_device
|
|
$ dd if=fip/u-boot.bin of=$DEV conv=fsync,notrunc bs=512 seek=1
