U-Boot compilation
|
|
------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ export CROSS_COMPILE=aarch64-none-elf-
|
|
$ make jethub_j80_defconfig
|
|
$ make
|
|
|
|
Image creation
|
|
--------------
|
|
|
|
For simplified usage, pleaser refer to :doc:`pre-generated-fip` with codename `jethub-j80`
|
|
|
|
Amlogic doesn't provide sources for the firmware and for tools needed
|
|
to create the bootloader image, so it is necessary to obtain binaries
|
|
from the git tree published by the board vendor:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ git clone https://github.com/jethome-ru/jethub-aml-tools jethub-u-boot
|
|
$ cd jethub-u-boot
|
|
$ export FIPDIR=$PWD
|
|
|
|
Go back to mainline U-Boot source tree then :
|
|
|
|
.. code-block:: bash
|
|
|
|
$ mkdir fip
|
|
|
|
$ cp $FIPDIR/j80/bl2.bin fip/
|
|
$ cp $FIPDIR/j80/acs.bin fip/
|
|
$ cp $FIPDIR/j80/bl21.bin fip/
|
|
$ cp $FIPDIR/j80/bl30.bin fip/
|
|
$ cp $FIPDIR/j80/bl301.bin fip/
|
|
$ cp $FIPDIR/j80/bl31.img fip/
|
|
$ cp u-boot.bin fip/bl33.bin
|
|
|
|
$ $FIPDIR/blx_fix.sh \
|
|
fip/bl30.bin \
|
|
fip/zero_tmp \
|
|
fip/bl30_zero.bin \
|
|
fip/bl301.bin \
|
|
fip/bl301_zero.bin \
|
|
fip/bl30_new.bin \
|
|
bl30
|
|
|
|
$ python $FIPDIR/acs_tool.pyc fip/bl2.bin fip/bl2_acs.bin fip/acs.bin 0
|
|
|
|
$ $FIPDIR/blx_fix.sh \
|
|
fip/bl2_acs.bin \
|
|
fip/zero_tmp \
|
|
fip/bl2_zero.bin \
|
|
fip/bl21.bin \
|
|
fip/bl21_zero.bin \
|
|
fip/bl2_new.bin \
|
|
bl2
|
|
|
|
$ $FIPDIR/j80/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin
|
|
$ $FIPDIR/j80/aml_encrypt_gxl --bl3enc --input fip/bl31.img
|
|
$ $FIPDIR/j80/aml_encrypt_gxl --bl3enc --input fip/bl33.bin --compress lz4
|
|
$ $FIPDIR/j80/aml_encrypt_gxl --bl2sig --input fip/bl2_new.bin --output fip/bl2.n.bin.sig
|
|
$ $FIPDIR/j80/aml_encrypt_gxl --bootmk \
|
|
--output fip/u-boot.bin \
|
|
--bl2 fip/bl2.n.bin.sig \
|
|
--bl30 fip/bl30_new.bin.enc \
|
|
--bl31 fip/bl31.img.enc \
|
|
--bl33 fip/bl33.bin.enc
|
|
|
|
and then write the image to SD/eMMC with:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ DEV=/dev/your_sd_device
|
|
$ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
|
|
$ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444
