Pack sizes

EF: Pack size issue not blocking today. See a big diversity in packs. Modularity is interesting and small packs are a good design pattern. Don’t see how we put a hard limit - good topic for discussion and to provide some examples of good practice.

User stories

FR: User-stories implementation proposal: https://github.com/Open-CMSIS-Pack/Open-CMSIS-Pack/issues/43#issuecomment-976522084

Keywords

EF: Related to workspace discussion and keyword processing. Keep the most general ones related to workspace settings.

RK: Suggest to give it a go and see how it behaves. Just want default settings that make sense.

EF: Same as discussion about defining multiple boards in one solution - question about diversity in solutions.

RK: Feature rich solution at the moment - get feedback on how easy it is to implement.

Progress

FR: cprj are the output - can you remind which file is the input?

Non secure code is in the same directory as the secure code in the example

JK: CMSE library is created - called by the non-secure part. Have a common header file.

FR: If we want to deliver the non-secure project - want to deliver the header file and library. Want to have it in a separate folder.

RK: Think the dependency needs review.

Are you asking to separate the library from the output folder

FR: Need to deliver the header separately. My point is really only how to deliver the Non-Secure-Callable : i would like to keep it separated from the Secure. But this does not challenge the global flow.

RK: Understood - needs review

LM: Where are the linker scripts? Can I have the full view from the solution?

DB: Part of the startup. Components have configuration files. See it as part of the resources.

FR: How to leverage clayer?

DB: Need to merge the contents of it. Have an intermediate source directory where we can combine all the layers.

FR: Can be by reference - not copying?

JK: Ultimately it’s about the config files.

FR: Build types? How do you make the decision?

RK: Will be debug and optimisation

Complex Reference Software

FR: To me so many packs is a bit frightening and I am not sure it highlights the user-stories. I think we will focus more on packs than something else. Alternatives from my side: https://github.com/Open-CMSIS-Pack/Open-CMSIS-Pack/issues/43#issuecomment-976522084
