Hello Community!
BACKGROUND:
Before creating custom MX7D hardware from scratch I would like to create an addon board for the SABRE and test custom peripherals. This way, all peripherals can be tested with a known-to-work base platform. Once the peripherals are tested, the SoC/RAM/memory etc circuitry/hardware will be created and combined with the peripherals.
ETHERNET:
One of the peripherals is Ethernet and i would like to test my Ethernet Phy circuitry on the addon board.
SMI and RMII signals are needed.

Hi Lars
in general you are right:
ENET2 signals are multiplexed with EPDC signals and are accessible through the EPDC connector,
U36 enables RGMII2 signals using ENET_EN_B (GPIO1_IO04).

So if i pull GPIO1_IO04 high, then U36 "cuts" the connection between Phy and MX7?
Sounds good. Thank you.
