Hi all,

As the isolation level 3 PoC targets for AN521 and MUSCA_B1 only at the first stage, two level-3-specific linker script files are created for these two platforms.

And the common linker scripts are not changed now.

This would avoid affecting the platforms who do not support isolation level 3 with a big changed linker script.

The patch for specific linker scripts can be found here:

Best Regards,

Kevin

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:

And the HAL API docs:

Docs: Design of the TF-M isolation HAL

More patches will be coming soon, will keep you update-to-date.

Please help on reviews, thanks.

Best Regards,

Kevin
