18Introduction
19============
20
21Rock960 board family consists of Rock960 (Consumer Edition) and
22Ficus (Enterprise Edition) 96Boards featuring Rockchip RK3399 SoC.
23
24Common features implemented on both boards:
25 * CPU: ARMv8 64bit Big-Little architecture,
26 * Big: dual-core Cortex-A72
27 * Little: quad-core Cortex-A53
28 * IRAM: 200KB
29 * eMMC: 16/32GB eMMC 5.1
30 * PMU: RK808
31 * SD/MMC
32 * Display: HDMI/DP/MIPI
33 * Low Speed Expansion Connector
34 * High Speed Expansion Connector
35
36Additional features of Rock960:
37 * DRAM: 2GB/4GB LPDDR3 @ 1866MHz
38 * 1x USB 3.0 type A, 1x USB 2.0 type A (host mode only),
39 1x USB 3.0 type C OTG
40
41Additional features of Ficus:
42 * DRAM: 2GB/4GB DDR3 @ 1600MHz
43 * Ethernet
44 * 2x USB 3.0 type A, 2x USB 2.0 type A (host mode only),
45 1x USB 3.0 type C OTG
46
47Here is the step-by-step to boot to U-Boot on Rock960 boards.
48
49Get the Source and prebuild binary
50==================================
51
52 > git clone https://github.com/96rocks/rkbin.git
53 > git clone https://github.com/rockchip-linux/rkdeveloptool.git
54
55Compile the U-Boot
56==================
57
58 > cd ../u-boot
59 > cp ../rkbin/rk33/rk3399_bl31_v1.00.elf ./bl31.elf
60 > export CROSS_COMPILE=aarch64-linux-gnu-
61 > make rock960-rk3399_defconfig
62 > make
63
64Compile the rkdeveloptool
65=========================
66
67Follow instructions in latest README
68 > cd ../rkdeveloptool
69 > autoreconf -i
70 > ./configure
71 > make
72 > sudo make install
73
74Package the image
75=================
76
77Package the image for U-Boot SPL(option 1)
78--------------------------------
79 > cd ..
80 > tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin idbspl.img
81
82 Get idbspl.img in this step.
83
84Package the image for Rockchip miniloader(option 2)
85------------------------------------------
86 > cd ../rkbin
87 > ./tools/loaderimage --pack --uboot u-boot/u-boot-dtb.bin uboot.img 0x200000
88
89 > ../u-boot/tools/mkimage -n rk3399 -T rksd -d rk3399_ddr_933MHz_v1.08.bin idbloader.img
90 > cat ./rk33/rk3399_miniloader_v1.06.bin >> idbloader.img
91
92 Get uboot.img and idbloader.img in this step.
93
94Bootloader storage options
95==========================
96
97There are a few different storage options for the bootloader.
98This document explores two of these: eMMC and removable SD/MMC.
99
100Flash the image to eMMC
101=======================
102
103Flash the image with U-Boot SPL(option 1)
104-------------------------------
105Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
106 > rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin
107 > rkdeveloptool wl 64 u-boot/idbspl.img
108 > rkdeveloptool wl 0x4000 u-boot/u-boot.itb
109 > rkdeveloptool rd
110
111Flash the image with Rockchip miniloader(option 2)
112----------------------------------------
113Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
114 > rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin
115 > rkdeveloptool wl 0x40 idbloader.img
116 > rkdeveloptool wl 0x4000 uboot.img
117 > rkdeveloptool wl 0x6000 ./img/rk3399/trust.img
118 > rkdeveloptool rd
119
120Create a bootable SD/MMC
121========================
122
123The idbspl.img contains the first stage, and the u-boot.img the second stage.
124As explained in the Rockchip partition table reference [1], the first stage
125(aka loader1) start sector is 64, and the second stage start sector is 16384.
126
127Each sector is 512 bytes, which means the first stage offset is 32 KiB,
128and the second stage offset is 8 MiB.
129
130Note: the second stage location is actually not as per the spec,
131but defined by the SPL. Mainline SPL defines an 8 MiB offset for the second
132stage.
133
134Assuming the SD card is exposed by device /dev/mmcblk0, the commands
135to write the two stages are:
136
137 > dd if=idbspl.img of=/dev/mmcblk0 bs=1k seek=32
138 > dd if=u-boot.itb of=/dev/mmcblk0 bs=1k seek=8192
139
140Setting up the kernel and rootfs is beyond the scope of this document.
141
142And that is it
143==============
144
145You should be able to get U-Boot log in console/UART2(baurdrate 1500000)
