Add mention of a prerequisite needed to build the image. Also adjust the English wording in a few places. Ideally this should move to using binman to produce images, and avoid the manual steps.

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 Get some prerequisites ====================== You need the Python elftools.elf.elffile library for make_fit_atf.py to work: > sudo apt-get install python-pyelftools 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 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 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) For more detail, please reference to: http://opensource.rock-chips.com/wiki_Boot_option
