| U-Boot for Amlogic P212
 | |
| =======================
 | |
| 
 | |
| P212 is a reference board manufactured by Amlogic with the following
 | |
| specifications:
 | |
| 
 | |
|  - Amlogic S905X ARM Cortex-A53 quad-core SoC @ 1.5GHz
 | |
|  - ARM Mali 450 GPU
 | |
|  - 2GB DDR3 SDRAM
 | |
|  - 10/100 Ethernet
 | |
|  - HDMI 2.0 4K/60Hz display
 | |
|  - 2 x USB 2.0 Host
 | |
|  - eMMC, microSD
 | |
|  - Infrared receiver
 | |
|  - SDIO WiFi Module
 | |
|  - CVBS+Stereo Audio Jack
 | |
| 
 | |
| Schematics are available from Amlogic on demand.
 | |
| 
 | |
| U-Boot compilation
 | |
| ------------------
 | |
| 
 | |
| .. code-block:: bash
 | |
| 
 | |
|     $ export CROSS_COMPILE=aarch64-none-elf-
 | |
|     $ make p212_defconfig
 | |
|     $ make
 | |
| 
 | |
| Image creation
 | |
| --------------
 | |
| 
 | |
| For simplified usage, pleaser refer to :doc:`pre-generated-fip` with codename `p212`
 | |
| 
 | |
| 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 gxl_p212_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
 | |
| 
 | |
|     $ $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
