Re: [TF-M] Generated files location - TF-M

      Hi Andrej,
Thanks for reporting this. It looks like the dependency on TFM_TEST_PATH matters. We need to define something for managing these generated files.

Hi,
FYI:
For Windows (not Liniux) users, the command have to be:
...
set TFM_TEST_PATH=../tf-m-tests/test
python tools/tfm_parse_manifest_list.py -m tools/tfm_manifest_list.yaml -f tools/tfm_generated_file_list.yaml -o <output> ...
Also, all required Python modules have to be installed before (PyYAML, Jinja2)
Best regards,
Andrej Butok

Hi,
As an intermediate step, we've made a modification to the file generation code so that file can be generated without cmake being run.
This generation can be run by:
```
python3 tools/tfm_parse_manifest_list.py -m tools/tfm_manifest_list.yaml -f tools/tfm_generated_file_list.yaml -o <output dir> ```
Which will output the files into the specified output directory. if the `-o` flag is not provided then the files will be generated into the TFM source tree.
Note that this method still requires knowledge of the location of some dependencies, as this cannot be provided by cmake. When run in standalone mode, these paths are gathered from environment variables, and generation will fail if those variables are not set. Thus:
```
env TFM_TEST_PATH=$(realpath ../tf-m-tests/test) python3 tools/tfm_parse_manifest_list.py -m tools/tfm_manifest_list.yaml -f tools/tfm_generated_file_list.yaml
```

Hi Anton
If it's not possible to avoid a file generation now, it's good to have pre-generated files for a most typical configuration (l2, IPC etc.).
As I mentioned before, ideally to use TFM as a real component/framework without generation of any source code.
BUT If you believe, this requirement breaks a TFM concept, just tell us.
Thanks,
Andrej

Hi Andrej,
Essentially, do you mean to move the files back to code tree and synch them with templates manually as it was ?
Cheers,
Anton

Hi Anton,
Another option:
3. Avoid the mandatory on-the-fly generation.
    Try to make TFM a component/framework, which is configurable by compile & run time parameters.
Thanks,
Andrej

Hi,
Some source files in TF-M are templated and generated inside /<build_dir>/generated/ on the fly as a part of build process. This guaranty consistency between templates and generated but might make a trouble for IDE, where not all source files exist at the first run.
I see 2 options for solution:
1.  Explicitly generate those files via cmake as a part of IDE project creation (1 time action)
  2.  Relay on CMSIS Pack for IDE, where generated files must be presents Any alternative thoughts?
Anton
