- 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/Cortex-M0 binaries
- ===============================================
- > git clone git://git.theobroma-systems.com/arm-trusted-firmware.git
- > git clone git://git.theobroma-systems.com/rk3399-cortex-m0.git
- Compile the ATF
- ===============
- > cd arm-trusted-firmware
- > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31
- > cp build/rk3399/release/bl31.bin ../u-boot/bl31-rk3399.bin
- Compile the M0 firmware
- =======================
- > cd ../rk3399-cortex-m0
- > make CROSS_COMPILE=arm-cortex_m0-eabi-
- > cp rk3399m0.bin ../u-boot
- Compile the U-Boot
- ==================
- > cd ../u-boot
- > make CROSS_COMPILE=aarch64-linux-gnu- puma-rk3399_defconfig all
- Package the image
- =================
- Creating a SPL image for SD-Card/eMMC
- > tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin spl_mmc.img
- Creating a SPL image for SPI-NOR
- > tools/mkimage -n rk3399 -T rkspi -d spl/u-boot-spl.bin spl_nor.img
- Create the FIT image containing U-Boot proper, ATF, M0 Firmware, devicetree
- > make CROSS_COMPILE=aarch64-linux-gnu- u-boot.itb
- Flash the image
- ===============
- Copy the SPL to offset 32k for SD/eMMC, offset 0 for NOR-Flash and the FIT
- image to offset 256k card.
- SD-Card
- -------
- > dd if=spl_mmc.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
- > ./rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin
- > ./rkdeveloptool wl 64 ../spl_mmc.img
- > ./rkdeveloptool wl 512 ../u-boot.itb
- NOR-Flash
- ---------
- Writing the SPI NOR Flash requires a running U-Boot. For the sake of simplicity
- we assume you have a SD-Card with a partition containing the required files
- ready.
- > load mmc 1:1 ${kernel_addr_r} spl_nor.img
- > sf probe
- > sf erase 0 +$filesize
- > sf write $kernel_addr_r 0 ${filesize}
- > load mmc 1:1 ${kernel_addr_r} u-boot.itb
- > sf erase 0x40000 +$filesize
- > sf write $kernel_addr_r 0x40000 ${filesize}
- Reboot the system and you should see a U-Boot console on UART0 (115200n8).
