Hi Kevin,
Do you know any real (not academic) MCU application where L3 isolation is required? People ask, but I have nothing to tell. Even for L2 is difficult to find something, for most of cases L1 is enough.
Thanks, Andrej

Hi all,
We've finished the PoC of isolation level 3 along with the new TFM HAL on the feature branch. And now we are migrating the patches to master branch by cherry-picking, squashing and refining.
Here are the several topics ongoing parallel:

More patches will be coming soon, will keep you update-to-date. Please help on reviews, thanks.

Hi,
A new branch created for two repos 'TF-M/tf-m-tests' and 'TF-M/trusted-firmware-m', this feature branch is for isolation related patches merging. The POC patches would come in following days, first platform would be AN521. If you want to try this branch, please:
IMPORTANT: Checkout 'feature-isoaltion-level3' branch for both 'TF-M/tf-m-tests' and 'TF-M/trusted-firmware-m'.
