| 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). |
