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:

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

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 ARCH=arm64
61 > export CROSS_COMPILE=aarch64-linux-gnu-
62 > make rock960-rk3399_defconfig
63 > make

65Compile the rkdeveloptool
66=========================
67
68Follow instructions in latest README
69 > cd ../rkdeveloptool
70 > autoreconf -i
71 > ./configure
72 > make
73 > sudo make install
74
75Package the image
76=================
77
78Package the image for U-Boot SPL(option 1)
79--------------------------------
80 > cd ..
81 > tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin idbspl.img
82
83 Get idbspl.img in this step.
84
85Package the image for Rockchip miniloader(option 2)
86------------------------------------------
87 > cd ../rkbin
88 > ./tools/loaderimage --pack --uboot u-boot/u-boot-dtb.bin uboot.img 0x200000
89
90 > ../u-boot/tools/mkimage -n rk3399 -T rksd -d rk3399_ddr_933MHz_v1.08.bin idbloader.img
91 > cat ./rk33/rk3399_miniloader_v1.06.bin >> idbloader.img
92
93 Get uboot.img and idbloader.img in this step.
94
95Bootloader storage options
96==========================
97
98There are a few different storage options for the bootloader.
99This document explores two of these: eMMC and removable SD/MMC.
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 wl 0x40 idbloader.img
117 > rkdeveloptool wl 0x4000 uboot.img
118 > rkdeveloptool wl 0x6000 ./img/rk3399/trust.img
119 > rkdeveloptool rd
120
121Create a bootable SD/MMC
122========================
123
124The idbspl.img contains the first stage, and the u-boot.img the second stage.
125As explained in the Rockchip partition table reference [1], the first stage
126(aka loader1) start sector is 64, and the second stage start sector is 16384.
127
128Each sector is 512 bytes, which means the first stage offset is 32 KiB,
129and the second stage offset is 8 MiB.
130
131Note: the second stage location is actually not as per the spec,
132but defined by the SPL. Mainline SPL defines an 8 MiB offset for the second
133stage.
134
135Assuming the SD card is exposed by device /dev/mmcblk0, the commands
136to write the two stages are:
137
138 > dd if=idbspl.img of=/dev/mmcblk0 bs=1k seek=32
139 > dd if=u-boot.itb of=/dev/mmcblk0 bs=1k seek=8192
140
141Setting up the kernel and rootfs is beyond the scope of this document.
142
143And that is it
144==============
145
146You should be able to get U-Boot log in console/UART2(baurdrate 1500000)
