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 Package the image ================= The SPL image for SD-Card/eMMC is readily available in idbloader.img at the root of U-Boot after compilation. Creating an SPL image for SPI-NOR: > tools/mkimage -n rk3399 -T rkspi -d spl/u-boot-spl.bin idbloader-spi.img Flash the image =============== Copy the SPL to offset 32k for SD/eMMC, offset 0 for NOR-Flash and the FIT image to offset 256k. SD-Card ------- > dd if=idbloader.img of=/dev/sdb seek=64 > dd if=u-boot.itb of=/dev/sdb seek=512 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 ../idbloader.img > ./rkdeveloptool wl 512 ../u-boot.itb 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 ../idbloader-spi.img > ./rkdeveloptool wl 512 ../u-boot.itb
