Hi,
I am trying to implement programs in TEE on Trusty that applies to Jetson Xavier NX, Jetson AGX Xavier series, and Jetson TX2 series devices. And I want to store some confidential data in secure world (TEE), which may consume large memories (in GB). Is that possible ? By manifests for Trusted Applications, I am able to reset TRUSTY_APP_CONFIG_MIN_HEAP_SIZE and TRUSTY_APP_CONFIG_MIN_STACK_SIZE. Here comes the question : what are the maximal heap size and stack size for a TA ? I have read the architecture of Trusty from here, which didn’t solve my problem.
Please point out my possible misunderstandings.
Thanks in advance !
Hi,
Thanks a lot !
Could you please introduce a bit more about how to increase TOS memory ? Is that an operation from software side or an extensional service/hardware ?
Thanks.
I think that I misunderstood your last answer. So the TOS memory mentioned above is actually controlled by the configuration if carveout.tzdram.size, am I right ?
Another small question about max size of per port buffer in tipc connection, is it fixed to 4096B? Because I tried to increase it to 8192B, which failed to create the port.
Thanks !
