Get the Source and prebuild binary
==================================

  > mkdir ~/evb_rk3229
  > cd ~/evb_rk3229
  > git clone git://git.denx.de/u-boot.git
  > git clone https://github.com/OP-TEE/optee_os.git
  > git clone https://github.com/rockchip-linux/rkbin.git
  > git clone https://github.com/rockchip-linux/rkdeveloptool.git

Compile the OP-TEE
===============

  > cd optee_os
  > make clean
  > make CROSS_COMPILE=arm-none-eabi- PLATFORM=rockchip-rk322x
  Get tee-raw.bin in this step, copy it to U-Boot root dir:
  > cp out/arm-plat-rockchip/core/tee-raw.bin ../u-boot/tee.bin

Compile the U-Boot
==================

  > cd ../u-boot
  > make evb-rk3229_defconfig
  > TEE=tee.bin CROSS_COMPILE=arm-linux-gnueabihf- make

  Get u-boot-rockchip.bin in this step.

Compile the rkdeveloptool
=======================
  Follow instructions in latest README
  > cd ../rkdeveloptool
  > autoreconf -i
  > ./configure
  > make
  > sudo make install

  Get rkdeveloptool in you Host in this step.

Both origin binaries and Tool are ready now, choose either option 1 or
option 2 to deploy U-Boot.

Flash the image to eMMC
=======================
Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
  > cd ..
  > rkdeveloptool/rkdeveloptool db rkbin/rk32/rk322x_loader_v1.04.232.bin
  > rkdeveloptool/rkdeveloptool wl 64 u-boot/u-boot-rockchip.bin
  > rkdeveloptool/rkdeveloptool rd

Flash the image to SD card
==========================
  > dd if=u-boot/u-boot-rockchip.bin of=/dev/sdb seek=64

You should be able to get U-Boot log message with OP-TEE boot info:
