Download ARM Trusted Firmware
Rockchip ATF
Rockchip do not provide the ATF source code, you can find the ATF binaries in rkbin repository.
Upstream ATF
Get the source code from github:
git clone https://github.com/ARM-software/arm-trusted-firmware.git
Supported Devices
Upstream ARM Trusted Firmware support Rockchip SoCs:
RK3328
RK3368
Build ATF
Here is a mk-atf.sh script to build ATF.
$ cat mk-atf.sh #!/bin/bash make realclean CFLAGS='-gdwarf-2' \ CROSS_COMPILE=aarch64-linux-gnu- \ make PLAT=rk3399 DEBUG=0 ERROR_DEPRECATED=1 bl31
Because there is a blob of code for cortex-M0 in rk3399 ATF, so you need a compiler for it. Install it by:
sudo apt-get install gcc-arm-none-eabi
We can get bl31.elf bl31.bin when build completed.
Note: The latest version ATF(including rockchip version and upstream version) bl31.elf instead of bl31.bin, the bl31.bin is not available now.
Install ATF
Using U-Boot SPL FIT image
Copy the trust binary(optee.bin or bl31.elf) to u-boot root directory and rename it to tee.bin(armv7) or bl31.elf(armv8). Use below command to get u-boot.itb.
make u-boot.itb
The output u-boot.itb is a its based package including u-boot-nodtb.bin, board.dtb, and trust binaries which can be load by SPL.
Using Rockchip miniloader
Alternatively, you can use Rockchip miniloader and U-Boot instead which do not need SPL.
The ATF is loaded by miniloader, so it should be package to known format for miniloader
trust_merger rk_tools/RKTRUST/RK3399TRUST.ini trust.img
According to the partitions definition, write trust.img to offset 0x6000.
