Hello Arnaud,
Thanks for your quick response!
What you meant by ST Restricted?
I cloned the above repos and extracted the cmake toolchain files and other metal port files and am I able to build the latest upstream open-amp and libmetal libraries using those files. But the application builds are failing since it is unable to find the platform_info.h and platform_info.c and other related files. There should be a stm32h7 specific folder under system or machine that contains files for building application for STM32H7 device per my understanding. By restricted you meant I need to get these files from ST directly through some kind of agreement?
Other question that was in my previous email was that do I need to develop my own application to work with Zephyr RPMSG sample application? I can't find a compatible application under examples of open-amp in ST's repo or in upstream open-amp repo example folder.
Thanks,
Murali
