1. Article purpose[edit source]
This article aims to explain how to use the secure display feature thanks to the LTDC internal peripheral and the OP-TEE framework controlled by the Arm®-Cortex® A35.
This article also explains how to configure LTDC 3rd layer (Resolution, Window sizing, Opacity etc.) and how to make changes in OP-TEE RIF settings from External device tree so that LTDC 3rd Layer can be controlled via Arm®-Cortex® M33.
2. Prerequisites[edit source]
To run the STM32Cube Example to demonstrate the LTDC 3rd layer controlled by CM33 while displaying Standard HMI on OpenSTLinux running on Arm®-Cortex® A35, required hardware and software stacks are listed below:
- The STM32MP257x-EV1 Evaluation board
(including the default LVDS display Panel) - Refer to the Installing the STM32CubeMP2 Package to obtain and install the source code
- Refer to the new recommended IDE: STM32CubeIDE
