gpoulios opened a new pull request, #3069:
URL: https://github.com/apache/nuttx-apps/pull/3069
## Summary
Add an example app that opens a session with the device pseudo-TA and
enumerates the available devices (prints their UUIDs only).
The example showcases:
- opening the OP-TEE client driver
- printing its version
- opening a session
- allocating shared memory
- registering shared memory
- invoking a function to the TA referencing the shared memory
- closing the session
Enabled with CONFIG_EXAMPLES_OPTEE.
## Impact
No impact other than showcasing usage of the TEE driver and perhaps enabling
quick testing.
## Testing
Tested on an NXP i.MX93 running:
- TF-A: version v2.10.0, tag `lf-6.6.52_2.2.0`
- OP-TEE OS: revision 4.4 (60beb308810f9561), tag `lf-6.6.52_2.2.0`
- NuttX master, commit <TO BE PROVIDED SOON> with `CONFIG_DEV_OPTEE_SMC64`
- NuttX configs `imx93-evk:nsh` and `imx93-evk:knsh`
```
Available devices:
