When building U-Boot we select the architecture via Kconfig and not ARCH being passed in via the environment or make cmdline.

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 type-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 ATF
|
|
===========
|
|
|
|
> cd arm-trusted-firmware
|
|
> make realclean
|
|
> make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31
|
|
|
|
Get bl31.elf in this step, copy it to U-Boot root dir:
|
|
> cp build/rk3399/release/bl31/bl31.elf ../u-boot/
|
|
|
|
Or you can get the bl31.elf directly from Rockchip:
|
|
> cp rkbin/rk33/rk3399_bl31_v1.00.elf ../u-boot/bl31.elf
|
|
|
|
|
|
Compile U-Boot
|
|
==============
|
|
|
|
> cd ../u-boot
|
|
> 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 rkdeveloptool
|
|
=====================
|
|
|
|
Get rkdeveloptool installed on your Host in this step.
|
|
|
|
Follow instructions in latest README, example:
|
|
> cd ../rkdeveloptool
|
|
> autoreconf -i
|
|
> ./configure
|
|
> make
|
|
> sudo make install
|
|
|
|
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)
