This adds platform code for the Amlogic P212 reference board based on a Meson GXL (S905X) SoC with the Meson GXL configuration. This initial submission only supports UART and MMC/SDCard, support for the internal Ethernet PHY in Work In Progress.

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. |
||||
|
||||
Currently the u-boot port supports the following devices: |
||||
- serial |
||||
- eMMC, microSD |
||||
|
||||
u-boot compilation |
||||
================== |
||||
|
||||
> export ARCH=arm |
||||
> export CROSS_COMPILE=aarch64-none-elf- |
||||
> make p212_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: |
||||

||||
> 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 : |
||||
> mkdir fip |
||||
|
||||
> cp $FIPDIR/gxl/bl2.bin fip/ |
||||
> cp $FIPDIR/gxl/acs.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_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 |

--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 |
