SoM's signals mapping

Bora Lite

As known, Bora Lite requires an adapter to be mounted on the BoraXEVB carrier board. The adapter swap some signals to allow to use some carrier board peripherals routed on unavailable pins of the SoM. For this reason, it can be tricky to find out where the SoM's signals are routed at the carrier board level. The following table details such routing for PL banks. Here it is assumed to use an adapter with default mounting options.

SoM's signal		Routing options at carrier board level
