Introduction
============
RK3399 key features we might use in U-Boot:
* CPU: ARMv8 64bit Big-Little architecture,
* Big: dual-core Cortex-A72
* Little: quad-core Cortex-A53
* IRAM: 200KB
* DRAM: 4GB-128MB dual-channel
* eMMC: support eMMC 5.0/5.1, suport HS400, HS200, DDR50
* SD/MMC: support SD 3.0, MMC 4.51
* USB: USB3.0 typc-C port *2 with dwc3 controller
* USB2.0 EHCI host port *2
* Display: RGB/HDMI/DP/MIPI/EDP
evb key features:
* regulator: pwm regulator for CPU B/L
* PMIC: rk808
* debug console: UART2
In order to support Arm Trust Firmware(ATF), we can use either SPL or
miniloader from rockchip to do:
* do DRAM init
* load and verify ATF image
* load and verify U-Boot image
Here is the step-by-step to boot to U-Boot on rk3399.
Get the Source and prebuild binary
==================================
> mkdir ~/evb_rk3399
> cd ~/evb_rk3399
> git clone https://github.com/ARM-software/arm-trusted-firmware.git
> git clone https://github.com/rockchip-linux/rkbin.git
> git clone https://github.com/rockchip-linux/rkdeveloptool.git
Compile the ATF
===============
> cd arm-trusted-firmware
> make realclean
> make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31
Or you can get the bl31.elf directly from Rockchip:
cp rkbin/rk33/rk3399_bl31_v1.00.elf ../u-boot/bl31.elf
Get bl31.elf in this step, copy it to U-Boot root dir:
> cp bl31.elf ../u-boot/
Compile the U-Boot
==================
> cd ../u-boot
> export ARCH=arm64
> export CROSS_COMPILE=aarch64-linux-gnu-
> make evb-rk3399_defconfig
for firefly-rk3399, use below instead:
> make firefly-rk3399_defconfig
> make
> make u-boot.itb
Get spl/u-boot-spl.bin and u-boot.itb 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.
Package the image
=================
Package the image for U-Boot SPL(option 1)
--------------------------------
> cd ..
> tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin idbspl.img
Get idbspl.img in this step.
Package the image for Rockchip miniloader(option 2)
------------------------------------------
> cd ..
> cp arm-trusted-firmware/build/rk3399/release/bl31.elf rkbin/rk33
> ./rkbin/tools/trust_merger rkbin/tools/RK3399TRUST.ini
> ./rkbin/tools/loaderimage --pack --uboot u-boot/u-boot-dtb.bin uboot.img
Get trust.img and uboot.img in this step.
Flash the image to eMMC
=======================
Flash the image with U-Boot SPL(option 1)
-------------------------------
Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
> rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin
> rkdeveloptool wl 64 u-boot/idbspl.img
> rkdeveloptool wl 0x4000 u-boot/u-boot.itb
> rkdeveloptool rd
Flash the image with Rockchip miniloader(option 2)
----------------------------------------
Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
> rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin
> rkdeveloptool ul rkbin/rk33/rk3399_loader_v1.08.106.bin
> rkdeveloptool wl 0x4000 u-boot/uboot.img
> rkdeveloptool wl 0x6000 u-boot/trust.img
> rkdeveloptool rd
You should be able to get U-Boot log in console/UART2(baurdrate 1500000)
