U-Boot compilation
|
|
------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ export CROSS_COMPILE=aarch64-none-elf-
|
|
$ make odroid-c2_defconfig
|
|
$ make
|
|
|
|
Image creation
|
|
--------------
|
|
|
|
For simplified usage, pleaser refer to :doc:`pre-generated-fip` with codename `odroid-c2`
|
|
|
|
Amlogic doesn't provide sources for the firmware and for tools needed
|
|
to create the bootloader image, so it is necessary to obtain them from
|
|
the git tree published by the board vendor:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ DIR=odroid-c2
|
|
$ git clone --depth 1 \
|
|
https://github.com/hardkernel/u-boot.git -b odroidc2-v2015.01 \
|
|
$DIR
|
|
$ $DIR/fip/fip_create --bl30 $DIR/fip/gxb/bl30.bin \
|
|
--bl301 $DIR/fip/gxb/bl301.bin \
|
|
--bl31 $DIR/fip/gxb/bl31.bin \
|
|
--bl33 u-boot.bin \
|
|
$DIR/fip.bin
|
|
$ $DIR/fip/fip_create --dump $DIR/fip.bin
|
|
$ cat $DIR/fip/gxb/bl2.package $DIR/fip.bin > $DIR/boot_new.bin
|
|
$ $DIR/fip/gxb/aml_encrypt_gxb --bootsig \
|
|
--input $DIR/boot_new.bin \
|
|
--output $DIR/u-boot.img
|
|
$ dd if=$DIR/u-boot.img of=$DIR/u-boot.gxbb bs=512 skip=96
|
|
|
|
and then write the image to SD with:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ DEV=/dev/your_sd_device
|
|
$ BL1=$DIR/sd_fuse/bl1.bin.hardkernel
|
|
$ dd if=$BL1 of=$DEV conv=fsync bs=1 count=442
|
|
$ dd if=$BL1 of=$DEV conv=fsync bs=512 skip=1 seek=1
|
|
$ dd if=$DIR/u-boot.gxbb of=$DEV conv=fsync bs=512 seek=97
