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:
32 > export CROSS_COMPILE=aarch64-none-elf-
33 > make odroid-c2_defconfig
39 Amlogic doesn't provide sources for the firmware and for tools needed
40 to create the bootloader image, so it is necessary to obtain them from
41 the git tree published by the board vendor:
44 > git clone --depth 1 \
45 https://github.com/hardkernel/u-boot.git -b odroidc2-v2015.01 \
47 > $DIR/fip/fip_create --bl30 $DIR/fip/gxb/bl30.bin \
48 --bl301 $DIR/fip/gxb/bl301.bin \
49 --bl31 $DIR/fip/gxb/bl31.bin \
52 > $DIR/fip/fip_create --dump $DIR/fip.bin
53 > cat $DIR/fip/gxb/bl2.package $DIR/fip.bin > $DIR/boot_new.bin
54 > $DIR/fip/gxb/aml_encrypt_gxb --bootsig \
55 --input $DIR/boot_new.bin \
56 --output $DIR/u-boot.img
57 > dd if=$DIR/u-boot.img of=$DIR/u-boot.gxbb bs=512 skip=96
59 and then write the image to SD with:
61 > DEV=/dev/your_sd_device
62 > BL1=$DIR/sd_fuse/bl1.bin.hardkernel
63 > dd if=$BL1 of=$DEV conv=fsync bs=1 count=442
64 > dd if=$BL1 of=$DEV conv=fsync bs=512 skip=1 seek=1
65 > dd if=$DIR/u-boot.gxbb of=$DEV conv=fsync bs=512 seek=97
