Does there exist a certified hardware+software solution for a mixed criticality system, where:
- A generic Linux runs on one of the cores and uses one of the GPUs (hardware accelerated graphics over OpenGL ES), and
- A safety-certified RTOS runs on one of the cores and uses the other GPU (hardware accelerated graphics over OpenGL SC)
on an i.MX8 QuadMax?
Are the "zone of trust"/"resource domain controller" features enough for certification? Does one require further evidence to certify such a system? Is there a pre-certified solution available?
So, is there no information on such a mixed criticality system? Is it difficult to certify a system, which uses i.MX8 hardware hypervisor or separation technologies to share the resources between a non-safe Linux and a safe RTOS?
Is there a specific document or page that tells about a certified system with RTOS + Linux? The link goes to the overview page of i.MX 8X processors, but I could not find a specific reference to such a solution. It would great if you can point out where it talks of a certified/able system with Linux + safe RTOS.
The product portfolio is already confusing, the main i.MX8 processor page shows i.MX8X as a lower power variation with single GPU, however, under documentation of i.MX8X, there is this document, which names variations such as 8QuadXPlus with more cores.
And I could not find documentation about how to use Resource Domain Controller for safety on i.MX8.
