AM263Px MCU+ SDK: Ethernet interface (RGMII / MII) selection

| AM263Px MCU+ SDK 26.00.00 |

Ethernet interface (RGMII / MII) selection

The diagram below depicts the signals for RGMII and MII respectively.

Figure: Ethernet RGMII and MII Signalling

- RGMII is the default interface configured in SDK examples.
- To configure MII interface follow steps captured below:
  - Modify the following changes in CPSW example Syscfg-GUI

1. SOC Pinmux selection in 'Syscfg‑Gui → TI NETWORKING → Enet (CPSW) → CPSW Pinmux Config'

1.1. If 'Mac Port 1' is used, select `MII` from drop down against `RMII(1)/RGMII(1)/MII(1)`.
1.2. If 'Mac Port 2' is used, select `MII` from drop down against `RMII(2)/RGMII(2)/MII(2)`.

2. MII1 Pinmux selection in 'Syscfg‑Gui → TI NETWORKING → Enet (CPSW) → IO Set'

2.1. If 'Mac Port 1' is used, select `MII1` from drop down against `MII1`.
2.2. If 'Mac Port 2' is used, select `MII2` from drop down against `MII2`.

3. PHY Pinmux selection for "RX_ER" pin in 'Syscfg‑Gui → TI BOARD DRIVERS → ENETPHY (Enet CPSW/ICSS) → Extended Configuration'
