21Rock960 board family consists of Rock960 (Consumer Edition) and
22Ficus (Enterprise Edition) 96Boards featuring Rockchip RK3399 SoC.
23
24Common features implemented on both boards:

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),

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
64  > make u-boot.itb
65
66Compile the rkdeveloptool
67=========================
68
69Follow instructions in latest README
70  > cd ../rkdeveloptool
71  > autoreconf -i
72  > ./configure
73  > make
74  > sudo make install
75
76Package the image
77=================
78
79Package the image for U-Boot SPL(option 1)
80--------------------------------
81  > cd ..
82  > tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin idbspl.img
83
84  Get idbspl.img in this step.
85
86Package the image for Rockchip miniloader(option 2)
87------------------------------------------
88  > cd ../rkbin
89  > ./tools/loaderimage --pack --uboot u-boot/u-boot-dtb.bin uboot.img 0x200000
90
91  > ../u-boot/tools/mkimage -n rk3399 -T rksd -d rk3399_ddr_933MHz_v1.08.bin idbloader.img
92  > cat ./rk33/rk3399_miniloader_v1.06.bin >> idbloader.img
93
94  Get uboot.img and idbloader.img in this step.
95
96Bootloader storage options
97==========================
98
99There are a few different storage options for the bootloader.
100This document explores two of these: eMMC and removable SD/MMC.
101
102Flash the image to eMMC
103=======================
104
105Flash the image with U-Boot SPL(option 1)
106-------------------------------
107Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
108  > rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin
109  > rkdeveloptool wl 64 u-boot/idbspl.img
110  > rkdeveloptool wl 0x4000 u-boot/u-boot.itb
111  > rkdeveloptool rd
112
113Flash the image with Rockchip miniloader(option 2)
114----------------------------------------
115Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
116  > rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin
117  > rkdeveloptool wl 0x40 idbloader.img
118  > rkdeveloptool wl 0x4000 uboot.img
119  > rkdeveloptool wl 0x6000 ./img/rk3399/trust.img
120  > rkdeveloptool rd
121
122Create a bootable SD/MMC
123========================
124
125The idbspl.img contains the first stage, and the u-boot.img the second stage.
126As explained in the Rockchip partition table reference [1], the first stage
127(aka loader1) start sector is 64, and the second stage start sector is 16384.
128
129Each sector is 512 bytes, which means the first stage offset is 32 KiB,
130and the second stage offset is 8 MiB.
131
132Note: the second stage location is actually not as per the spec,
133but defined by the SPL. Mainline SPL defines an 8 MiB offset for the second
134stage.
135
136Assuming the SD card is exposed by device /dev/mmcblk0, the commands
137to write the two stages are:
138
139  > dd if=idbspl.img of=/dev/mmcblk0 bs=1k seek=32
140  > dd if=u-boot.itb of=/dev/mmcblk0 bs=1k seek=8192
141
142Setting up the kernel and rootfs is beyond the scope of this document.
143
144And that is it
145==============
146
147You should be able to get U-Boot log in console/UART2(baurdrate 1500000)
