Hello everyone! I have a Jetson tx2, where three cores are assigned to linux kernel and one to FreeRTOS (using jailhouse hypervisor). I need to share a buffer between two processes that run in these two operating systems.
The problem is that in Linux I have to deal with virtual addresses and in FreeRTOS I don’t. And I don’t know much about jetson mmu. The question is how can I write the buffer in a known physical address, where processes in both operating system can read/write? Do you have any suggetions or documentation about it?
Thank you so much!
