21 Rock960 board family consists of Rock960 (Consumer Edition) and
22 Ficus (Enterprise Edition) 96Boards featuring Rockchip RK3399 SoC.
24 Common features implemented on both boards:
25 * CPU: ARMv8 64bit Big-Little architecture,
26 * Big: dual-core Cortex-A72
27 * Little: quad-core Cortex-A53
29 * eMMC: 16/32GB eMMC 5.1
32 * Display: HDMI/DP/MIPI
33 * Low Speed Expansion Connector
34 * High Speed Expansion Connector
36 Additional 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),
41 Additional features of Ficus:
42 * DRAM: 2GB/4GB DDR3 @ 1600MHz
44 * 2x USB 3.0 type A, 2x USB 2.0 type A (host mode only),
47 Here is the step-by-step to boot to U-Boot on Rock960 boards.
49 Get the Source and prebuild binary
50 ==================================
52 > git clone https://github.com/96rocks/rkbin.git
53 > git clone https://github.com/rockchip-linux/rkdeveloptool.git
59 > cp ../rkbin/rk33/rk3399_bl31_v1.00.elf ./bl31.elf
61 > export CROSS_COMPILE=aarch64-linux-gnu-
62 > make rock960-rk3399_defconfig
66 Compile the rkdeveloptool
67 =========================
69 Follow instructions in latest README
79 Package the image for U-Boot SPL(option 1)
80 --------------------------------
82 > tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin idbspl.img
84 Get idbspl.img in this step.
86 Package the image for Rockchip miniloader(option 2)
87 ------------------------------------------
89 > ./tools/loaderimage --pack --uboot u-boot/u-boot-dtb.bin uboot.img 0x200000
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
94 Get uboot.img and idbloader.img in this step.
96 Bootloader storage options
97 ==========================
99 There are a few different storage options for the bootloader.
100 This document explores two of these: eMMC and removable SD/MMC.
102 Flash the image to eMMC
103 =======================
105 Flash the image with U-Boot SPL(option 1)
106 -------------------------------
107 Power 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
113 Flash the image with Rockchip miniloader(option 2)
114 ----------------------------------------
115 Power 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
122 Create a bootable SD/MMC
123 ========================
125 The idbspl.img contains the first stage, and the u-boot.img the second stage.
126 As 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.
129 Each sector is 512 bytes, which means the first stage offset is 32 KiB,
130 and the second stage offset is 8 MiB.
132 Note: the second stage location is actually not as per the spec,
133 but defined by the SPL. Mainline SPL defines an 8 MiB offset for the second
136 Assuming the SD card is exposed by device /dev/mmcblk0, the commands
137 to write the two stages are:
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
142 Setting up the kernel and rootfs is beyond the scope of this document.
147 You should be able to get U-Boot log in console/UART2(baurdrate 1500000)
