4RK3399 key features we might use in U-Boot:
5* CPU: ARMv8 64bit Big-Little architecture,
6* Big: dual-core Cortex-A72
7* Little: quad-core Cortex-A53
8* IRAM: 200KB
9* DRAM: 4GB-128MB dual-channel
10* eMMC: support eMMC 5.0/5.1, suport HS400, HS200, DDR50
11* SD/MMC: support SD 3.0, MMC 4.51
12* USB: USB3.0 type-C port *2 with dwc3 controller
13* USB2.0 EHCI host port *2
14* Display: RGB/HDMI/DP/MIPI/EDP
15
16evb key features:
17* regulator: pwm regulator for CPU B/L
18* PMIC: rk808
19* debug console: UART2
20
21In order to support Arm Trust Firmware(ATF), we can use either SPL or
22miniloader from rockchip to do:
23* do DRAM init
24* load and verify ATF image
25* load and verify U-Boot image
26
27Here is the step-by-step to boot to U-Boot on rk3399.
28
29Get the Source and prebuild binary
30==================================
31
32 > mkdir ~/evb_rk3399
33 > cd ~/evb_rk3399
34 > git clone https://github.com/ARM-software/arm-trusted-firmware.git
35 > git clone https://github.com/rockchip-linux/rkbin.git
36 > git clone https://github.com/rockchip-linux/rkdeveloptool.git
37
38
39Compile ATF
40===========
41
42 > cd arm-trusted-firmware
43 > make realclean
44 > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31
45
46 Get bl31.elf in this step, copy it to U-Boot root dir:
47 > cp build/rk3399/release/bl31/bl31.elf ../u-boot/
48
49 Or you can get the bl31.elf directly from Rockchip:
50 > cp rkbin/rk33/rk3399_bl31_v1.00.elf ../u-boot/bl31.elf
51
52
53Compile U-Boot
54==============
55
56 > cd ../u-boot
57 > export ARCH=arm64
58 > export CROSS_COMPILE=aarch64-linux-gnu-
59 > make evb-rk3399_defconfig
60 for firefly-rk3399, use below instead:
61 > make firefly-rk3399_defconfig
62 > make
63 > make u-boot.itb
64
65 Get spl/u-boot-spl.bin and u-boot.itb in this step.
66
67Compile rkdeveloptool
68=====================
69
70Get rkdeveloptool installed on your Host in this step.
71
72Follow instructions in latest README, example:
73 > cd ../rkdeveloptool
74 > autoreconf -i
75 > ./configure
76 > make
77 > sudo make install
78
79Both origin binaries and Tool are ready now, choose either option 1 or
80option 2 to deploy U-Boot.
81
82Package the image
83=================
84
85Package the image for U-Boot SPL(option 1)
86--------------------------------
87 > cd ..
88 > tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin idbspl.img
89
90 Get idbspl.img in this step.
91
92Package the image for Rockchip miniloader(option 2)
93------------------------------------------
94 > cd ..
95 > cp arm-trusted-firmware/build/rk3399/release/bl31.elf rkbin/rk33
96 > ./rkbin/tools/trust_merger rkbin/tools/RK3399TRUST.ini
97 > ./rkbin/tools/loaderimage --pack --uboot u-boot/u-boot-dtb.bin uboot.img
98
99 Get trust.img and uboot.img in this step.
100
101Flash the image to eMMC
102=======================
103
104Flash the image with U-Boot SPL(option 1)
105-------------------------------
106Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
107 > rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin
108 > rkdeveloptool wl 64 u-boot/idbspl.img
109 > rkdeveloptool wl 0x4000 u-boot/u-boot.itb
110 > rkdeveloptool rd
111
112Flash the image with Rockchip miniloader(option 2)
113----------------------------------------
114Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
115 > rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin
116 > rkdeveloptool ul rkbin/rk33/rk3399_loader_v1.08.106.bin
117 > rkdeveloptool wl 0x4000 u-boot/uboot.img
118 > rkdeveloptool wl 0x6000 u-boot/trust.img
119 > rkdeveloptool rd
120
121You should be able to get U-Boot log in console/UART2(baurdrate 1500000)
