  1. U-Boot for ODROID-C2
  2. ====================
  3. ODROID-C2 is a single board computer manufactured by Hardkernel
  4. Co. Ltd with the following specifications:
  5. - Amlogic S905 ARM Cortex-A53 quad-core SoC @ 2GHz
  6. - ARM Mali 450 GPU
  7. - 2GB DDR3 SDRAM
  8. - Gigabit Ethernet
  9. - HDMI 2.0 4K/60Hz display
  10. - 40-pin GPIO header
  11. - 4 x USB 2.0 Host, 1 x USB OTG
  12. - eMMC, microSD
  13. - Infrared receiver
  14. Schematics are available on the manufacturer website.
  15. Currently the u-boot port supports the following devices:
  16. - serial
  17. - eMMC, microSD
  18. - Ethernet
  19. - I2C
  20. - Regulators
  21. - Reset controller
  22. - Clock controller
  23. - ADC
  24. u-boot compilation
  25. ==================
  26. > export ARCH=arm
  27. > export CROSS_COMPILE=aarch64-none-elf-
  28. > make odroid-c2_defconfig
  29. > make
  30. Image creation
  31. ==============
  32. Amlogic doesn't provide sources for the firmware and for tools needed
  33. to create the bootloader image, so it is necessary to obtain them from
  34. the git tree published by the board vendor:
  35. > DIR=odroid-c2
  36. > git clone --depth 1 \
  37. https://github.com/hardkernel/u-boot.git -b odroidc2-v2015.01 \
  38. $DIR
  39. > $DIR/fip/fip_create --bl30 $DIR/fip/gxb/bl30.bin \
  40. --bl301 $DIR/fip/gxb/bl301.bin \
  41. --bl31 $DIR/fip/gxb/bl31.bin \
  42. --bl33 u-boot.bin \
  43. $DIR/fip.bin
  44. > $DIR/fip/fip_create --dump $DIR/fip.bin
  45. > cat $DIR/fip/gxb/bl2.package $DIR/fip.bin > $DIR/boot_new.bin
  46. > $DIR/fip/gxb/aml_encrypt_gxb --bootsig \
  47. --input $DIR/boot_new.bin \
  48. --output $DIR/u-boot.img
  49. > dd if=$DIR/u-boot.img of=$DIR/u-boot.gxbb bs=512 skip=96
  50. and then write the image to SD with:
  51. > DEV=/dev/your_sd_device
  52. > BL1=$DIR/sd_fuse/bl1.bin.hardkernel
  53. > dd if=$BL1 of=$DEV conv=fsync bs=1 count=442
  54. > dd if=$BL1 of=$DEV conv=fsync bs=512 skip=1 seek=1
  55. > dd if=$DIR/u-boot.gxbb of=$DEV conv=fsync bs=512 seek=97
