I'm building an Yocto image using on a Var-som-mx8m-nano with Scarthgap. (https://dev.variscite.com/var-som-mx8m-nano/mx8mn-yocto-scarthgap-6.6.52_2.2.0-v1.1/yocto-build-rele...)
I've followed this guide: https://community.nxp.com/t5/i-MX-Processors/Building-optee-examples-and-trusted-Apps-in-Yocto-bitba...
Although this answer is old, I've added the Optee-examples version 4.7, and populated the .bb file with the information found in that link. The local.conf file I edited according to the official docs since the advice on the answer is depreciated.
However, the rest of the optee files are version 4.4. If I try to bitbake optee-examples without adding the .bb file, I get an error saying there's no target.
I ran bitbake -DDD optee-examples
I get the following error:

I am stuck:
- there is no * file in the location /home/optee/var-fsl-yocto/build_xwayland/tmp/work/imx8mn_var_som-poky-linux/optee-examples/4.7.0/build/ta/*'
- I don't know what type of file it's looking for to create one
- It doesn't solve the do_install error either
Any help is appreciated.

Please try to keep the versions consistent. The default BSP includes an optee file and example recipes for reference.

Thanks! If the default bsp includes optee examples, how would I access those without bitbake optee-examples? My goal is to use the examples to help build a TA for a use case I have.

To add on, since I can't edit my original reply. All the other optee files I was able to build successfully.So if there's a way to access the optee examples if they are included, that would be optimal.
There's something within Scarthgap that really doesn't like optee-examples. I was able to find the 4.4 version of optee-examples and I still got an error:
| install: cannot stat '/home/optee/var-fsl-yocto/build_xwayland/tmp/work/imx8mn_var_som-poky-linux/optee-examples/4.4.0/build/ta/*': No such file or directory
