  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. u-boot compilation
  20. ==================
  21. > export ARCH=arm
  22. > export CROSS_COMPILE=aarch64-none-elf-
  23. > make odroid-c2_defconfig
  24. > make
  25. Image creation
  26. ==============
  27. Amlogic doesn't provide sources for the firmware and for tools needed
  28. to create the bootloader image, so it is necessary to obtain them from
  29. the git tree published by the board vendor:
  30. > DIR=odroid-c2
  31. > git clone --depth 1 \
  32. https://github.com/hardkernel/u-boot.git -b odroidc2-v2015.01 \
  33. $DIR
  34. > $DIR/fip/fip_create --bl30 $DIR/fip/gxb/bl30.bin \
  35. --bl301 $DIR/fip/gxb/bl301.bin \
  36. --bl31 $DIR/fip/gxb/bl31.bin \
  37. --bl33 u-boot.bin \
  38. $DIR/fip.bin
  39. > $DIR/fip/fip_create --dump $DIR/fip.bin
  40. > cat $DIR/fip/gxb/bl2.package $DIR/fip.bin > $DIR/boot_new.bin
  41. > $DIR/fip/gxb/aml_encrypt_gxb --bootsig \
  42. --input $DIR/boot_new.bin \
  43. --output $DIR/u-boot.img
  44. > dd if=$DIR/u-boot.img of=$DIR/u-boot.gxbb bs=512 skip=96
  45. and then write the image to SD with:
  46. > DEV=/dev/your_sd_device
  47. > BL1=$DIR/sd_fuse/bl1.bin.hardkernel
  48. > dd if=$BL1 of=$DEV conv=fsync bs=1 count=442
  49. > dd if=$BL1 of=$DEV conv=fsync bs=512 skip=1 seek=1
  50. > dd if=$DIR/u-boot.gxbb of=$DEV conv=fsync bs=512 seek=97
