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,Is there any way to reset SFLP "Game vector" readings at runtime, once SFLP enabled?For instance, after few minutes of SFLP run, it reports (after quaternion to Euler conversion) YAW: 1.5, PITCH: 0.5, ROLL: 0.1. And I'd like to reset Yaw to 0 (zer...

Hi, newly released CubeMX 6.11.1 still doesn't fix an issue that ThreadX cannot be selected for TouchGFX for TrustZone-enabled projects. It has been reported and admitted quite a while ago. See here:https://community.st.com/t5/stm32-mcus-touchgfx-and...

HI Jocelyn and thanks for your suggestions: we'll definitely try them!However, from what we see: it might be easier indeed to use SBSFU with something like Mbed Crypto (for any additional secure services) than deal with TFM as it is implemented...For...

HI Jocelynthank you very much for asking.We'd expect:1. We have TrustZone-enabled Secure+NonSecure application, with ThreadX and TouchGFX, using CubeMX as hardware configurator.We need to port in to to TFM for the following reasons, in order of impor...
