  2. U-Boot for Amlogic P201
  3. =======================
  4. P201 is a reference board manufactured by Amlogic with the following
  5. specifications:
  6. - Amlogic S905 ARM Cortex-A53 quad-core SoC @ 1.5GHz
  7. - ARM Mali 450 GPU
  8. - 2GB DDR3 SDRAM
  9. - 10/100 Ethernet
  10. - HDMI 2.0 4K/60Hz display
  11. - 2 x USB 2.0 Host
  12. - eMMC, microSD
  13. - Infrared receiver
  14. - SDIO WiFi Module
  15. - CVBS+Stereo Audio Jack
  16. Schematics are available from Amlogic on demand.
  17. U-Boot compilation
  18. ------------------
  19. .. code-block:: bash
  20. $ export CROSS_COMPILE=aarch64-none-elf-
  21. $ make p201_defconfig
  22. $ make
  23. Image creation
  24. --------------
  25. Amlogic doesn't provide sources for the firmware and for tools needed
  26. to create the bootloader image, so it is necessary to obtain them from
  27. the git tree published by the board vendor:
  28. .. code-block:: bash
  29. $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
  30. $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
  31. $ tar xvfJ gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
  32. $ tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
  33. $ 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
  34. $ git clone https://github.com/BayLibre/u-boot.git -b n-amlogic-openlinux-20170606 amlogic-u-boot
  35. $ cd amlogic-u-boot
  36. $ make gxb_p201_v1_defconfig
  37. $ make
  38. $ export FIPDIR=$PWD/fip
  39. Go back to mainline U-boot source tree then :
  40. .. code-block:: bash
  41. $ mkdir fip
  42. $ cp $FIPDIR/gxl/bl2.bin fip/
  43. $ cp $FIPDIR/gxl/acs.bin fip/
  44. $ cp $FIPDIR/gxl/bl21.bin fip/
  45. $ cp $FIPDIR/gxl/bl30.bin fip/
  46. $ cp $FIPDIR/gxl/bl301.bin fip/
  47. $ cp $FIPDIR/gxl/bl31.img fip/
  48. $ cp u-boot.bin fip/bl33.bin
  49. $ $FIPDIR/blx_fix.sh \
  50. fip/bl30.bin \
  51. fip/zero_tmp \
  52. fip/bl30_zero.bin \
  53. fip/bl301.bin \
  54. fip/bl301_zero.bin \
  55. fip/bl30_new.bin \
  56. bl30
  57. $ $FIPDIR/acs_tool.pyc fip/bl2.bin fip/bl2_acs.bin fip/acs.bin 0
  58. $ $FIPDIR/blx_fix.sh \
  59. fip/bl2_acs.bin \
  60. fip/zero_tmp \
  61. fip/bl2_zero.bin \
  62. fip/bl21.bin \
  63. fip/bl21_zero.bin \
  64. fip/bl2_new.bin \
  65. bl2
  66. $ $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin
  67. $ $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl31.img
  68. $ $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl33.bin
  69. $ $FIPDIR/gxl/aml_encrypt_gxl --bl2sig --input fip/bl2_new.bin --output fip/bl2.n.bin.sig
  70. $ $FIPDIR/gxl/aml_encrypt_gxl --bootmk \
  71. --output fip/u-boot.bin \
  72. --bl2 fip/bl2.n.bin.sig \
  73. --bl30 fip/bl30_new.bin.enc \
  74. --bl31 fip/bl31.img.enc \
  75. --bl33 fip/bl33.bin.enc
  76. and then write the image to SD with:
  77. .. code-block:: bash
  78. $ DEV=/dev/your_sd_device
  79. $ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
  80. $ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444
