U-Boot for Amlogic P201
|
||||
=======================
|
||||
|
||||
P201 is a reference board manufactured by Amlogic with the following
|
||||
specifications:
|
||||
|
||||
- Amlogic S905 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.
|
||||
|
||||
Currently the u-boot port supports the following devices:
|
||||
- serial
|
||||
- eMMC, microSD
|
||||
- Ethernet
|
||||
- I2C
|
||||
- Regulators
|
||||
- Reset controller
|
||||
- Clock controller
|
||||
- USB Host
|
||||
- ADC
|
||||
|
||||
u-boot compilation
|
||||
==================
|
||||
|
||||
> export ARCH=arm
|
||||
> export CROSS_COMPILE=aarch64-none-elf-
|
||||
> make p201_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:
|
||||
|
||||
> 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 :
|
||||
> 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
|
||||
> $FIPDIR/gxl/aml_encrypt_gxl --bootmk \
|
||||
--output fip/u-boot.bin \
|
||||
--bl2 fip/bl2.n.bin.sig \
|
||||
--bl30 fip/bl30_new.bin.enc \
|
||||
--bl31 fip/bl31.img.enc \
|
||||
--bl33 fip/bl33.bin.enc
|
||||
|
||||
and then write the image to SD with:
|
||||
|
||||
> DEV=/dev/your_sd_device
|
||||
> dd if=fip/u-boot.bin.sd.bin of=$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
