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 binary
30 ===================================
32 > git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
37 > cd trusted-firmware-a
38 > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31
39 > cp build/rk3399/release/bl31/bl31.elf ../u-boot/bl31.elf
45 > make CROSS_COMPILE=aarch64-linux-gnu- puma-rk3399_defconfig all
50 The SPL image for SD-Card/eMMC is readily available in idbloader.img at the
51 root of U-Boot after compilation.
53 Creating an SPL image for SPI-NOR:
54 > tools/mkimage -n rk3399 -T rkspi -d spl/u-boot-spl.bin idbloader-spi.img
59 Copy the SPL to offset 32k for SD/eMMC, offset 0 for NOR-Flash and the FIT
65 > dd if=idbloader.img of=/dev/sdb seek=64
66 > dd if=u-boot.itb of=/dev/sdb seek=512
71 rkdeveloptool allows to flash the on-board eMMC via the USB OTG interface with
72 help of the Rockchip loader binary.
