AM4376: MMC2_CMD pin

Marco Fontanesi
Intellectual 305 points
Part Number: AM4376

Hi,

I found in a commercial SOM with AM437x that the MMC2_CMD pin  is  multiplexed  with  MDIO_DATA.

But I need both MMC2 and ethernet peripherals:  is there a way to use both peripherals ?

thanks.

    Hi,

    MMC2_CMD is available on the following processor pins: A13, A17, AE22, B12.
    MDIO_DATA is available on the following processor pins: A17.

    What you should do is check which of these pins have been routed out on your SOM. If you find available pins, you should also use the Pinmux tool (www.ti.com/.../PINMUXTOOL ) to check that the MMC2 (resp. MDIO) pin combination falls within a valid IO set, i.e. that the tool does not generate errors with the pins you intend to use.
