U-Boot for Beelink GT-King Pro
==============================
The Shenzen AZW (Beelink) GT-King Pro is based on the Amlogic W400 reference
board with an S922X-H chip.
- 4GB LPDDR4 RAM
- 64GB eMMC storage
- 10/100/1000 Base-T Ethernet
- AP6356S Wireless (802.11 a/b/g/n/ac, BT 4.1)
- HDMI 2.1 video
- Analogue audio output
- 1x RS232 port
- 2x USB 2.0 port
- 2x USB 3.0 ports
- IR receiver
- 1x SD card slot
- 1x Power on/off button
Beelink do not provide public schematics, but have been willing
to share them with known distro developers on request.
U-Boot compilation
------------------
.. code-block:: bash
$ export CROSS_COMPILE=aarch64-none-elf-
$ make beelink-gtkingpro_defconfig
$ make
Image creation
--------------
Amlogic does not provide sources for the firmware and for tools needed
to create the bootloader image. Beelink have provided the Amlogic "SDK"
in their forums, but the u-boot sources included result in 2GB RAM being
detected. The following FIPs were generated with newer private sources
and give correct (4GB) RAM detection:
https://github.com/LibreELEC/amlogic-boot-fip/tree/master/beelink-s922x
NB: Beelink use a common board config for GT-King, GT-King Pro and the
GS-King-X model, hence the "beelink-s922x" name.
For simplified usage, pleaser refer to :doc:`pre-generated-fip` with codename `beelink-s922x`
.. code-block:: bash
$ wget https://github.com/LibreELEC/amlogic-boot-fip/archive/master.zip
$ unzip master.zip
$ export FIPDIR=$PWD/amlogic-boot-fip/beelink-s922x
Go back to the mainline U-Boot source tree then:
.. code-block:: bash
$ mkdir fip
$ cp $FIPDIR/* fip/
$ cp u-boot.bin fip/bl33.bin
$ sh fip/blx_fix.sh \
fip/bl30.bin \
fip/zero_tmp \
fip/bl30_zero.bin \
fip/bl301.bin \
fip/bl301_zero.bin \
fip/bl30_new.bin \

$ sh fip/blx_fix.sh \
fip/bl2.bin \
fip/zero_tmp \
fip/bl2_zero.bin \

fip/bl21_zero.bin \
fip/bl2_new.bin \

$ fip/aml_encrypt_g12b --bl30sig --input fip/bl30_new.bin \
--output fip/bl30_new.bin.g12a.enc \
--level v3
$ fip/aml_encrypt_g12b --bl3sig --input fip/bl30_new.bin.g12a.enc \
--output fip/bl30_new.bin.enc \
--level v3 --type bl30
$ fip/aml_encrypt_g12b --bl3sig --input fip/bl31.img \
--output fip/bl31.img.enc \

$ fip/aml_encrypt_g12b --bl3sig --input fip/bl33.bin --compress lz4 \
--output fip/bl33.bin.enc \
--level v3 --type bl33
$ fip/aml_encrypt_g12b --bl2sig --input fip/bl2_new.bin \
--output fip/bl2.n.bin.sig
$ fip/aml_encrypt_g12b --bootmk \
--output fip/u-boot.bin \

and then write the image to SD 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
