> I am also leaning towards supporting `no_std` TAs (target: `aarch64-unknown-none`) for OP-TEE given there are many crates supporting `no_std` features too. We only need heap support and rest APIs are provided by GP internal APIs. I would like to hear from `incubator-teaclave-trustzone-sdk` project maintainers if they are aware of any gaps here. I have some experience with what need to implement: 1) heap support: We Can implement a simple global memory allocator which just call C function malloc,realloc and free 2) GP APIs: just use FFI to wrap C GP-APIs 3) panic handler: Can implement a simple panic handler which just call panic functions provided by OP-TEE (like TEE_Panic) > One of the difference I saw with `aarch64-unknown-teeos` is the threading support in TAs which isn't supported for OP-TEE based TAs. So if we really need to support `std` library then it should be a different target. Yes -- This is an automated message from the Apache Git Service.
