U-Boot for JetHub J100 (A113X)
|
|
==============================
|
|
|
|
JetHome Jethub D1 (http://jethome.ru/jethub-d1) is a home automation controller device
|
|
manufactured by JetHome with the following specifications:
|
|
|
|
- Amlogic A113X (ARM Cortex-A53) quad-core up to 1.5GHz
|
|
- no video out
|
|
- 512MB/1GB DDR3 or 2GB DDR4 SDRAM
|
|
- 8/16/32GB eMMC flash
|
|
- 1 x USB 2.0
|
|
- 1 x 10/100Mbps ethernet
|
|
- WiFi / Bluetooth one from:
|
|
- AMPAK AP6255 (Broadcom BCM43455) IEEE 802.11a/b/g/n/ac, Bluetooth 4.2

U-Boot Compilation
|
|
------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ export CROSS_COMPILE=aarch64-none-elf-
|
|
$ make jethub_j100_defconfig
|
|
$ make
|
|
|
|
U-Boot Signing with Pre-Built FIP repo
|
|
--------------------------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ git clone https://github.com/LibreELEC/amlogic-boot-fip --depth=1
|
|
$ cd amlogic-boot-fip
|
|
$ mkdir my-output-dir
|
|
$ ./build-fip.sh jethub-j100 /path/to/u-boot/u-boot.bin my-output-dir
|
|
|
|
U-Boot Manual Signing
|
|
---------------------
|
|
|
|
Amlogic does not provide sources for the firmware and tools needed to create a bootloader
|
|
image so it is necessary to obtain binaries from sources 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 the mainline U-Boot source tree then:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ mkdir fip
|
|
|
|
$ cp $FIPDIR/j100/bl2.bin fip/
|
|
$ cp $FIPDIR/j100/acs.bin fip/
|
|
$ cp $FIPDIR/j100/bl21.bin fip/
|
|
$ cp $FIPDIR/j100/bl30.bin fip/
|
|
$ cp $FIPDIR/j100/bl301.bin fip/
|
|
$ cp $FIPDIR/j100/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
|
|
|
|
$ $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/j100/aml_encrypt_axg --bl3sig --input fip/bl30_new.bin \
|
|
--output fip/bl30_new.bin.enc \
|
|
--level v3 --type bl30
|
|
$ $FIPDIR/j100/aml_encrypt_axg --bl3sig --input fip/bl31.img \
|
|
--output fip/bl31.img.enc \
|
|
--level v3 --type bl31
|
|
$ $FIPDIR/j100/aml_encrypt_axg --bl3sig --input fip/bl33.bin --compress lz4 \
|
|
--output fip/bl33.bin.enc \
|
|
--level v3 --type bl33
|
|
$ $FIPDIR/j100/aml_encrypt_axg --bl2sig --input fip/bl2_new.bin \
|
|
--output fip/bl2.n.bin.sig
|
|
$ $FIPDIR/j100/aml_encrypt_axg --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 --level v3
|
|
|
|
Then write U-Boot to SD or eMMC with:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ DEV=/dev/boot_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=440
|
