| * 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. |
| |
