5 Co. Ltd with the following specifications:
7 - Amlogic S905 ARM Cortex-A53 quad-core SoC @ 2GHz
11 - HDMI 2.0 4K/60Hz display
13 - 4 x USB 2.0 Host, 1 x USB OTG
17 Schematics are available on the manufacturer website.
19 Currently the u-boot port supports the following devices:
28 > export CROSS_COMPILE=aarch64-none-elf-
29 > make odroid-c2_defconfig
35 Amlogic doesn't provide sources for the firmware and for tools needed
36 to create the bootloader image, so it is necessary to obtain them from
37 the git tree published by the board vendor:
40 > git clone --depth 1 \
41 https://github.com/hardkernel/u-boot.git -b odroidc2-v2015.01 \
43 > $DIR/fip/fip_create --bl30 $DIR/fip/gxb/bl30.bin \
44 --bl301 $DIR/fip/gxb/bl301.bin \
45 --bl31 $DIR/fip/gxb/bl31.bin \
48 > $DIR/fip/fip_create --dump $DIR/fip.bin
49 > cat $DIR/fip/gxb/bl2.package $DIR/fip.bin > $DIR/boot_new.bin
50 > $DIR/fip/gxb/aml_encrypt_gxb --bootsig \
51 --input $DIR/boot_new.bin \
52 --output $DIR/u-boot.img
53 > dd if=$DIR/u-boot.img of=$DIR/u-boot.gxbb bs=512 skip=96
55 and then write the image to SD with:
57 > DEV=/dev/your_sd_device
58 > BL1=$DIR/sd_fuse/bl1.bin.hardkernel
59 > dd if=$BL1 of=$DEV conv=fsync bs=1 count=442
60 > dd if=$BL1 of=$DEV conv=fsync bs=512 skip=1 seek=1
61 > dd if=$DIR/u-boot.gxbb of=$DEV conv=fsync bs=512 seek=97
