HI,we are interested in a guide to a clear workflow of integrating CubeMX-generated code for U5 into TFM-based application.In particular:1. We have trustzone-enabled CubeMX-generated app with Azure RTOS and TouchGFX. The IDE and compiler are IAR. We...
Hi,In our application, we want to authenticate our IoT devices in Azure IoT Hub using X509 certificates with the help of STSAFE-A110. The application is written in Zephyr RTOS and is using the MbedTLS library for the TLS part. Using the in-tree Zephy...
Hi Team,I am working on project in which we are implementing Secure software upgrade feature using SBSFU. locally I am building SBSFU package, but our project follows different process. To meet that I need to build SBSFU package in TeamCity.could any...
