Looking at this a bit further it is indeed a serious issue, since most modern applications are going to want to make use of the FPU. This prevents the FPU from being used inside NS interrupts as well.
I’m not sure if there are currently any change requests that identify or fix this problem (I’ll look), but it’s something that should have some sort of test on the NS side, for sure.
Do you mind filing the details on TF-M’s phabricator and it can more easily be tracked there?
Thanks for bringing this up, Kevin
