Booting on RK3399[Please note, mail behalf by sjg at google.com]

[Piotr Lobacz]

Hi all,
i also have a firefly-rk3399 and got problems booting atf >= 1.4 with
whatever optee i use. Only rockchip blob is working for me. I know that i'm
doing something wrong but dunno what. The command for building atf is:
 
# make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 LOG_LEVEL=40 DEBUG=0
CRASH_REPORTING=1 SPD=opteed bl31

and i only generate uboot.img and trust.img using rockchip build.sh script
with command

# ./buid.sh uboot

Rockchip has added this trust_merger app to their u-boot source code. The
build.sh script builds u-boot and executes make.sh script from u-boot which
runs trust_merger. But for some reason it does not work atf >= 1.4. I don't
know what exectly but what i can tell, i do not see any logs from bl31. For
atf 1.3 with rockchip bl32 blob i can see logs:

No find bl30.bin

And this is what i get for 2.3 atf version:

find part:trust OK. first_lba:0x6000.

No find bl30.bin

U-Boot 2017.09 (Nov 11 2020 - 10:27:07 +0100)

Model: Firefly-RK3399 Board
PreSerial: 2
DRAM:  3.8 GiB
Sysmem: init
Relocation Offset is: f5beb000
Using default environment

There is no NOTICE or INFO log. The bl32 blob is the same so i suspect for
99% that bl31 was not initialized.

Can anybody help me solving this issue? Because currently i'm with no more
ideas and this is really frustrating...

Best Regards
