Dear Experts,

We have a design requirement with STM32H755 to work with Parallel Redundancy Protocol (PRP). Any relevant help or sources available.

Thanks in advance.

PRP can be implemented entirely in software, i.e. integrated in the network driver.

If using lwIP, you don't even need multiple netif interfaces for this, because all of the PRP handling should happen at driver level.
