Download ARM Trusted Firmware
Get the source code from github:
git clone https://github.com/ARM-software/arm-trusted-firmware.git
Supported Devices[edit]
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, 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 complete.
Install ATF
Using U-Boot SPL FIT image
Using Rockchip miniloader
Alternatively, you can use Rockchip miniloader and U-Boot instead which do not need SPL.
The ATF is load by miniloader, so it should be package to know format for minloader
trust_merger rk_tools/RKTRUST/RK3399TRUST.ini atf.img
According to the partitions definition, write to atf.img offset 0x6000.
