Any thoughts on how to debug it?
I couldn't get upstream TF-A to work. Here is how I am building it:
make CROSS_COMPILE=aarch64-linux-gnu- PLAT=tegra TARGET_SOC=t186 DEBUG=1 all
then I build tos.img as following:
./gen_tos_part_img.py bl31.bin JetPack_4.2_Linux_P3310/Linux_for_Tegra/bootloader/tos.img
(try to)flash as following:
./flash.sh -k secure-os jetson-tx2 mmcblk0p1
However, I can't get flashing to work as soon as tos.img from R32.1 is
replaced with my build. Is upstream TF-A supposed to work with R32.1?
Alternatively, I can do the testing this week if you provide me any TF-A debug builds.
Thanks,
Yousaf
