| 2 | |
| 3 | Get the Source and build ATF |
| 4 | ============================ |
| 5 | |
| 6 | > git clone git://git.theobroma-systems.com/arm-trusted-firmware.git |
| 7 | > cd arm-trusted-firmware |
| 8 | > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3368 bl31 |
| 9 | > cp build/rk3368/release/bl31.bin ../u-boot/bl31-rk3368.bin |
| 10 | |
| 11 | Configure U-Boot |
| 12 | ================ |
| 13 | |
| 14 | > cd ../u-boot |
| 15 | > make lion-rk3368_defconfig |
| 16 | |
| 17 | Build the TPL/SPL stage |
| 18 | ======================= |
| 19 | |
| 20 | > make CROSS_COMPILE=aarch64-unknown-elf- ARCH=arm |
| 21 | > tools/mkimage -n rk3368 -T rksd -d tpl/u-boot-tpl.bin spl-3368.img |
| 22 | > cat spl/u-boot-spl-dtb.bin >> spl-3368.img |
| 23 | |
| 24 | Build the full U-Boot and a FIT image including the ATF |
| 25 | ======================================================= |
| 26 | |
| 27 | > make CROSS_COMPILE=aarch64-unknown-elf- ARCH=arm u-boot.itb |
| 28 | |
| 29 | Write to a SD-card |
| 30 | ================== |
| 31 | |
| 32 | > dd if=spl-3368.img of=/dev/sdb seek=64 |
| 33 | > dd if=u-boot.itb of=/dev/sdb seek=512 |
| 34 | |
| 35 | |
| 36 | If everything went according to plan, you should see the following |
| 37 | output on UART0: |
| 38 | |
| 39 | <debug_uart> U-Boot TPL board init |
| 40 | Trying to boot from BOOTROM |
| 41 | Returning to boot ROM... |
