  3. =======================
  4. Q200 is a reference board manufactured by Amlogic with the following
  5. specifications:
  6. - Amlogic S912 ARM Cortex-A53 octo-core SoC @ 1.5GHz
  7. - ARM Mali T860 GPU
  8. - 2/3GB DDR4 SDRAM

  10. - HDMI 2.0 4K/60Hz display
  11. - 2 x USB 2.0 Host, 1 x USB 2.0 Device
  12. - 16GB/32GB/64GB eMMC
  13. - 2MB SPI Flash
  14. - microSD
  15. - SDIO Wifi Module, Bluetooth
  16. - IR receiver
  17. U-Boot compilation
  18. ------------------
  19. .. code-block:: bash
  20. $ export CROSS_COMPILE=aarch64-none-elf-
  21. $ make khadas-vim2_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 gxm_q200_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. $ python $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
