Do you see and trace print to the console? Like:
[+] TA create
[+] TA open session

No I did not get those info.
This is the full console output:

Actually, I didn't test this on 3.7.0. We do have tutorial to run it in 3.4.0 on QEMU: https://github.com/mesalock-linux/rust-optee-trustzone-sdk/wiki/Getting-started-with-OPTEE-for-QEMU-ARMv8

If 3.7 still follow the GlobalPlatform API, the library should be okay. Another thing you may try is to increase the TEE RAM size since Rust's code is later than C and we didn't do any optimization.

[ShaleXIONG]

I see cool ! I will try on 3.4.0. The hello_world TA from rust is around 100K, while the same TA from C is around 80K. I doubt it is the problem off TEE RAM but I will try that too.

Hi, any update on this issue?

[ShaleXIONG]

I was busy with other things. I have tested the 3.7 on QEMU, which works, but did not find a time to try further, e.g. 3.4 on Rpi or increase the TEE RAM size. I will post here if I get any update.

I'm closing this issue. Feel free to reopen it if you have any update. Thanks.
