Can pin 50 of the Colibri iMX8X be used as the “RMII_CRS_DV” input for ethernet RMII ? If so, what “ALT” mode is required for this functionality?

The Colibri documentation needs more clarification and definition when using RMII.

Thanks

  • Yes

  • ALT 3 - CONN.ENET1.RGMII_RX_CTL

Please check NXP i.MX 8DualX/8DualXPlus/8QuadXPlus Applications Processor Reference Manual Chapter 14.6 Ethernet MAC (ENET) for more clarification and definition about using RMII.
