MSPM33C321A-Q1: CMSE lib + example projects

HS FAE Germany

Part Number: MSPM33C321A-Q1
Other Parts Discussed in Thread: LP-MSPM33C321A

Hello,
customer wants to use the TrustZone and read the MSPM33C Security User's Guide SLUUDG7.
Will we offer the CMSE lib?
Do we offer TrustZone examples?

Hi Holger

Yes, we offer both the Cortex-M Security Extensions (CMSE) mechanisms and specific TrustZone software examples.

Here is what you need to know regarding the support provided for the MSPM33C:

1. CMSE Support

The tiarmclang compiler toolchain included with the MSPM33 SDK natively supports Armv8-M Cortex-M Security Extensions (CMSE). software-dl.ti.com/.../index.html

Rather than requiring a standalone pre-compiled static library, compiler intrinsics and attributes are built right into the compilation system.
To use CMSE mechanisms in your source files, developers simply include the <arm_cmse.h> header file and activate CMSE flags inside the tiarmclang compiler settings. https://software-dl.ti.com/codegen/docs/tiarmclang/rel2_1_0_LTS/compiler_manual/cortex_m_security_extensions/index.html

2. TrustZone Examples

The MSPM33 Software Development Kit (SDK) includes specialized Trusted Firmware-M (TF-M) project examples built specifically for the MSPM33C architecture. https://dev.ti.com/tirex/explore/node?node=A__AE4rG5bvDO.mJC0shMUzIg__MSPM33-SDK__4L387NB__LATEST

These examples demonstrate how to create isolated codespaces using secure and non-secure application partitioning.
You can find reference templates such as tfm_empty_ns within the MSPM33 SDK Examples Guide tailored to evaluate on the LP-MSPM33C321A LaunchPad.
