Hi Antonio, Ken, Miklos,
Currently, we use a preprocessor flag `TFM_MULTI_CORE_TOPOLOGY` to comment the veneer sections in the templates in multi-core topology. Each time before building, we have to run the Python script to generate new link script/scatter file with veneer disabled, to replace the existing ones. It becomes more inconvenient as the number of developers and users on feature-twincpu branch grows.
As Chris proposed on https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Freview.tru..., does it also make sense to directly update the "generated" linker script/scatter file as well, on feature-twincpu branch? `TFM_MULTI_CORE_TOPOLOGY` will be a common flag used in multi-core topology and will help resolve our urgent problem. If the final improvement solution is completed on master branch, we will update the feature branch accordingly when merging it back to master branch.
Please let me know if there is a better option for feature-twincpu branch. Thank you.
Best regards, Hu Ziji

Hi Chris,
you are right, that file is autogenerated from the template file but both are kept under source control. The reason for this is that the autogenerated file is not created at build time but by manually running the tfm_parse_manifest_list.py, which has to be run every time something in the manifest is changed, and the resulting autogenerated file is committed under source control as well.
On the other hand, the build system could be modified to run the parsers at build time so that the autogenerated files wouldn't have to be stored in source control, and we could keep only the template. These two alternatives are both equally valid in my view, but if there is strong consensus for the other we can discuss.
Thanks, Antonio

Can somebody please help me understand this? $ ls platform/ext/common/armclang/ tfm_common_s.sct tfm_common_s.sct.template $ ls platform/ext/common/gcc tfm_common_s.ld tfm_common_s.ld.template In both directories, both files are under source control, but the non-template files say that they're auto-generated: /*********** WARNING: This is an auto-generated file. Do not edit! ***********/
It's unusual to see both the source file and the artifact under source control.
It seems that they're generated by tools/tfm_parse_manifest_list.py, but that doesn't seem to be run as part of the build, so when is it run?
Thanks,
Chris

Hi Andrej,
Could you help to tell the name of the file you don't want to be removed? So that we can estimate what is important for IDE projects and how we could help on that.
An introduction of how your IDE integrate with TF-M code is also welcome. Would you share this to us?
Thanks.
-Ken

Hi Ken,
Could you help to tell the name of the file you don't want to be removed?
So, any .c,.h,.inc and linker file which may be used during compilation. An IDE project (ARM Kei, MCUx, IAR etc.) assumes a fixed set of existing files.
Thanks, Andrej
