Question
Firmware Deployment on STM32MP157D M4 Core
I am working on building a Yocto-based Linux distribution for the STM32MP157D SoC. I have already set up the process to build the Linux image successfully. However, I need guidance on the following:
Deploying Firmware on M4 Core
- What is the correct procedure to deploy firmware on the M4 coprocessor core of the STM32MP157D?
- Are there any best practices or considerations I should keep in mind while deploying firmware on the M4 core?
Communication between A7 and M4 Cores
- How can I establish communication between the main A7 core (running Linux) and the M4 coprocessor core?
- Are there any examples or sample code available to demonstrate the communication between the two cores?
I would greatly appreciate any guidance, documentation references, or code examples that could help me accomplish these tasks efficiently. Thank you in advance for your assistance.
