Hi All,

We will merge this patch (https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/2147/) to TF-M during the day. It adds the cbor 1.0.0 Python package to the list of tools that are required to build TF-M. Once it is merged, this package has to be installed in the build environment, otherwise the builds will fail. The cbor package can be installed with the following command: pip3 install --user cbor (or manually after downloading the package from here: https://pypi.org/project/cbor/).

Regards, David Vincze
