Other Parts Discussed in Thread: DRA821
I'm designing a mixed functional safety + Linux based system for an industrial application. The MCU island on DRA821 has an Ethernet port, which is great. DRA821 also has a 5-port switch on the main domain. I need more than one Ethernet port in the safe domain- can I externally loop the MCU port to the 5-port switch and use that? I guess I'm asking if the 5-port switch on its own can be made functionally safe when Linux is running in the main domain.
Or should I expect to have to use an external switch with some kind of safety rating for this? (Does TI have such a switch?)
Thanks!
Joe
