How to check the image size of ATF (ARM Trusted firmware) in TX2?
When ATF is running, how much memory does it take up?

hello 18810758767,

may I know what’s the actual use-case?
it’s bl31.bin of your arm-trusted-firmware, however, it’s actually used by script file, gen_tos_part_img.py to create tos.img and flash to secure-os partition.

Thanks for your reply!

Yes, I have generated bl31.bin, lk.bin, and generated tos.img with gen_tos_part_img.py.
But if I want to know how much memory ATF will occupy at runtime, how can I check the runtime memory size of ATF in TX2?

hello 18810758767,

you may check CBoot logs for the details of allocations.
you’re able to modify tegra186-mb1-bct-misc-si-l4t.cfg for TX2 to increase the tzdram size (TOS memory region).
please also check this thread as see-also, Topic 186972.
thanks
