Description
Serial Loopback is not supported in Arria® V or Cyclone® V devices with GX transceivers.
The Triple Speed Ethernet (TSE) user guide states that, "The serial loopback option is not supported in Stratix® V and Cyclone IV devices with GX transceiver."
Details regarding Arria V and Cyclone V devices haven't yet been included in the TSE user guide.
This paragraph will be updated to state that Arria V and Cyclone V devices do not support PHY Loopback, either.
