  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. - Ethernet
  18. u-boot compilation
  19. ==================
  20. > export ARCH=arm
  21. > export CROSS_COMPILE=aarch64-none-elf-
  22. > make odroid-c2_defconfig
  23. > make
  24. Image creation
  25. ==============
  26. Amlogic doesn't provide sources for the firmware and for tools needed
  27. to create the bootloader image, so it is necessary to obtain them from
  28. the git tree published by the board vendor:
  29. > DIR=odroid-c2
  30. > git clone --depth 1 \
  31. https://github.com/hardkernel/u-boot.git -b odroidc2-v2015.01 \
  32. $DIR
  33. > $DIR/fip/fip_create --bl30 $DIR/fip/gxb/bl30.bin \
  34. --bl301 $DIR/fip/gxb/bl301.bin \
  35. --bl31 $DIR/fip/gxb/bl31.bin \
  36. --bl33 u-boot.bin \
  37. $DIR/fip.bin
  38. > $DIR/fip/fip_create --dump $DIR/fip.bin
  39. > cat $DIR/fip/gxb/bl2.package $DIR/fip.bin > $DIR/boot_new.bin
  40. > $DIR/fip/gxb/aml_encrypt_gxb --bootsig \
  41. --input $DIR/boot_new.bin \
  42. --output $DIR/u-boot.img
  43. > dd if=$DIR/u-boot.img of=$DIR/u-boot.gxbb bs=512 skip=96
  44. and then write the image to SD with:
  45. > DEV=/dev/your_sd_device
  46. > BL1=$DIR/sd_fuse/bl1.bin.hardkernel
  47. > dd if=$BL1 of=$DEV conv=fsync bs=1 count=442
  48. > dd if=$BL1 of=$DEV conv=fsync bs=512 skip=1 seek=1
  49. > dd if=$DIR/u-boot.gxbb of=$DEV conv=fsync bs=512 seek=97
