Support for TrustZone and MultiCore

Quick question.

 

I am working on two projects:

  • One is a dual-core project, and uses the STM32H755 and CMSIS-RTOS v2 over Free RTOS. 
    • I often have to debug two boards simultaneously.

  • Another project is using STM32H573. This uses TrustZone and ThreadX (on the non-secure side).

Both are currently managed via ST Cube IDE (Eclipse based of course) and debugging is already quite "complex".

I can see advantages with VS Code, but moreover, I would not be surprised if the VS Code route becomes the de-facto standard some day (purely speculative of course), so I think I may need to start looking at it.

Before I do, my question to the community is whether the VS Code option is yet mature enough for dual core and TrustZone projects?

Many thanks in advance,

Nick

There is one snag - when I try to convert the project, I get the following error:

STM32CubeIDE multi-context and multi-core projects are not supported yet.

Maybe there is another way to migrate dual-core projects?

Hi @NickO,

Yes that's one of the listed limitations with our current converter version. We're actively working on it though.
