Hi Thomas,

Are you building from the master branch or feature-twincpu? I'm assuming the latter because psoc6 support hasn't yet made it back to the master branch. Which config(s) did you try to build? The feature-twincpu branch is being built pretty regularly for psoc6 (with both clang and gcc), so it should work. There's a document at platform/ext/target/psoc6//cypress_psoc_6_spec.rst detailing exactly how to build.

If you can send the details of exactly what commands you're executing and what results you're getting, somebody should be able to help.

Chris

I have been tasked with making the twincpu feature work with the IAR toolchain, and I started out trying to build it with clang and gcc but it seems there's some issues with it.

I tried using the psoc6 target, but it appears that none of the v6/v7 targets are supported in configs/ConfigDefault.cmake. If I add that the build then fails with a complaint about "Armv6-M/Armv7-M can only support multi-core TF-M now." from tfm_arch_v6m_v7m.h, due to TFM_MULTI_CORE_TOPOLOGY not being set, but that appears to be set in one of the cmake files so I guess something is currently broken.

Is this a known issue and is there are known fix?

/Thomas
