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:
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=1 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.bin when build completed.
Install ATF
Using U-Boot SPL FIT image
Upstream U-Boot SPL support for ATF still WIP.
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 know format for miniloader
trust_merger rk_tools/RKTRUST/RK3399TRUST.ini atf.img
According to the partitions definition, write to atf.img offset 0x6000.
