+
+U-Boot Compilation
+------------------
+
+.. code-block:: bash
+
+ $ export CROSS_COMPILE=aarch64-none-elf-
+ $ make videostrong-kii-pro_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 wetek-play2 /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 and Videostrong has not publicly shared the U-Boot sources
+needed to build FIP binaries for signing. However you can use the WeTek
+Play2 binaries from the amlogic-boot-fip repo as the WeTek Play2 and the
+Videostrong KII Pro share the same RAM chips.
+
+.. code-block:: bash
+
+ $ git clone https://github.com/LibreELEC/amlogic-boot-fip --depth=1
+ $ cd amlogic-boot-fip/wetek-play2
+ $ export FIPDIR=$PWD
+
+Go back to the mainline U-Boot source tree then:
+
+.. code-block:: bash
+
+ $ mkdir fip
+ $ cp $FIPDIR/bl2.bin fip/
+ $ cp $FIPDIR/acs.bin fip/
+ $ cp $FIPDIR/bl21.bin fip/
+ $ cp $FIPDIR/bl30.bin fip/
+ $ cp $FIPDIR/bl301.bin fip/
+ $ cp $FIPDIR/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/fip_create --bl30 fip/bl30_new.bin \
+ --bl31 fip/bl31.img \
+ --bl33 fip/bl33.bin \
+ fip/fip.bin
+ $ sed -i 's/\x73\x02\x08\x91/\x1F\x20\x03\xD5/' fip/bl2.bin
+ $ python3 $FIPDIR/acs_tool.py 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
+ $ cat fip/bl2_new.bin fip/fip.bin > fip/boot_new.bin
+ $ $FIPDIR/aml_encrypt_gxb --bootsig \
+ --input fip/boot_new.bin
+ --output fip/u-boot.bin
+
+Then write U-Boot to SD or eMMC with:
+
+.. code-block:: bash
+
+ $ DEV=/dev/boot_device
+ $ dd if=fip/u-boot.bin of=fip/u-boot.bin.gxbb bs=512 conv=fsync
+ $ dd if=fip/u-boot.bin of=fip/u-boot.bin.gxbb bs=512 seek=9 skip=8 count=87 conv=fsync,notrunc
+ $ dd if=/dev/zero of=fip/u-boot.bin.gxbb bs=512 seek=8 count=1 conv=fsync,notrunc
+ $ dd if=bl1.bin.hardkernel of=fip/u-boot.bin.gxbb bs=512 seek=2 skip=2 count=1 conv=fsync,notrunc
+ $ ./aml_chksum fip/u-boot.bin.gxbb
+ $ dd if=fip/u-boot.bin.gxbb of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
+ $ dd if=fip/u-boot.bin.gxbb of=$DEV conv=fsync,notrunc bs=1 count=440
