4 The RK3399-Q7 (Puma) is a system-on-module featuring the Rockchip
5 RK3399 in a Qseven-compatible form-factor.
8 * CPU: ARMv8 64bit Big-Little architecture,
9 * Big: dual-core Cortex-A72
10 * Little: quad-core Cortex-A53
12 * DRAM: 4GB-128MB dual-channel
15 * GbE (onboard Micrel KSZ9031) Gigabit ethernet PHY
17 * USB3.0 dual role port
18 * 2x USB3.0 host, 1x USB2.0 host via onboard USB3.0 hub
19 * Display: HDMI/eDP/MIPI
20 * Camera: 2x CSI (one on the edge connector, one on the Q7 specified CSI ZIF)
21 * NOR Flash: onboard SPI NOR
22 * Companion Controller: onboard additional Cortex-M0 microcontroller
27 Here is the step-by-step to boot to U-Boot on rk3399.
29 Get the Source and build ATF/Cortex-M0 binaries
30 ===============================================
32 > git clone git://git.theobroma-systems.com/arm-trusted-firmware.git
33 > git clone git://git.theobroma-systems.com/rk3399-cortex-m0.git
38 > cd arm-trusted-firmware
39 > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31
40 > cp build/rk3399/release/bl31.bin ../u-boot
42 Compile the M0 firmware
43 =======================
45 > cd ../rk3399-cortex-m0
46 > make CROSS_COMPILE=arm-cortex_m0-eabi-
47 > cp rk3399m0.bin ../u-boot
53 > make CROSS_COMPILE=aarch64-linux-gnu- puma-rk3399_defconfig all
58 > tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin spl.img
59 > make CROSS_COMPILE=aarch64-linux-gnu- u-boot.itb
64 Copy the SPL to offset 32k and the FIT image containing the payloads
65 (U-Boot proper, ATF, M0 Firmware, devicetree) to offset 256k on a SD
68 > dd if=spl.img of=/dev/sdb seek=64
69 > dd if=u-boot.itb of=/dev/sdb seek=512
71 After powering up the board (with the inserted SD card), you should see
72 a U-Boot console on UART0 (115200n8).
