Introduction
============
The RK3399-Q7 (Puma) is a system-on-module featuring the Rockchip
RK3399 in a Qseven-compatible form-factor.
RK3399-Q7 features:
* CPU: ARMv8 64bit Big-Little architecture,
* Big: dual-core Cortex-A72
* Little: quad-core Cortex-A53
* IRAM: 200KB
* DRAM: 4GB-128MB dual-channel
* eMMC: onboard eMMC
* SD/MMC
* GbE (onboard Micrel KSZ9031) Gigabit ethernet PHY
* USB:
* USB3.0 dual role port
* 2x USB3.0 host, 1x USB2.0 host via onboard USB3.0 hub
* Display: HDMI/eDP/MIPI
* Camera: 2x CSI (one on the edge connector, one on the Q7 specified CSI ZIF)
* NOR Flash: onboard SPI NOR
* Companion Controller: onboard additional Cortex-M0 microcontroller
* RTC
* fan controller
* CAN
Here is the step-by-step to boot to U-Boot on rk3399.
Get the Source and build ATF binary
===================================
> git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
Compile the ATF
===============
> cd trusted-firmware-a
> make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31
> cp build/rk3399/release/bl31/bl31.elf ../u-boot/bl31.elf
Compile the U-Boot
==================
> cd ../u-boot
> make CROSS_COMPILE=aarch64-linux-gnu- puma-rk3399_defconfig all
Flash the image
===============
Copy u-boot-rockchip.bin to offset 32k for SD/eMMC.
Copy u-boot-rockchip-spi.bin to offset 0 for NOR-flash.
SD-Card
-------
> dd if=u-boot-rockchip.bin of=/dev/sdb seek=64
eMMC
----
rkdeveloptool allows to flash the on-board eMMC via the USB OTG interface with
help of the Rockchip loader binary.
> git clone https://github.com/rockchip-linux/rkdeveloptool
> cd rkdeveloptool
> autoreconf -i && ./configure && make
> git clone https://github.com/rockchip-linux/rkbin.git
> cd rkbin
> ./tools/boot_merger RKBOOT/RK3399MINIALL.ini
> cd ..
> ./rkdeveloptool db rkbin/rk3399_loader_v1.25.126.bin
> ./rkdeveloptool wl 64 ../u-boot-rockchip.bin
NOR-Flash
---------
rkdeveloptool allows to flash the on-board SPI via the USB OTG interface with
help of the Rockchip loader binary.
> git clone https://github.com/rockchip-linux/rkdeveloptool
> cd rkdeveloptool
> autoreconf -i && ./configure && make
> git clone https://github.com/rockchip-linux/rkbin.git
> cd rkbin
> ./tools/boot_merger RKBOOT/RK3399MINIALL_SPINOR.ini
> cd ..
> ./rkdeveloptool db rkbin/rk3399_loader_spinor_v1.25.114.bin
> ./rkdeveloptool ef
> ./rkdeveloptool wl 0 ../u-boot-rockchip-spi.bin
