Ethernet Mux configuration for T4160RDB-64B

[vinothkumars]

Hi All,

I am working Ethernet on T4160RDB-64B. I want to configure the Ethernet MUX  Configuration. The default RCW value for RGMII and I configured to GPIO.

I want to configure the following Ethernet Pins,

EC1_TX_EN/GPIO3_12

EC1_TXD3/GPIO3_08

EC1_TXD2/GPIO3_09

EC1_TXD1/GPIO3_10

EC1_TXD0/GPIO3_11

EC1_RX_DV/GPIO3_14

EC1_RX_CLK/GPIO3_15

EC1_RXD3/GPIO3_16

EC1_RXD2/GPIO3_17

EC1_RXD1/GPIO3_18

EC1_RXD0/GPIO3_19

EC1_GTX_CLK125

EC1_GTX_CLK/GPIO3_13

Regards,

VinothS

To configure EC1 pins as GPIO3 it is required to set RCW[EC1]=10 - refer to the QorIQ T4240 Reference Manual, Table 4-13. RCW Field Descriptions, EC1.

The EC1_GTX_CLK125 does not have secondary function - refer to the QorIQ T4160/T4080 Data Sheet, Table 1. Pinout list by bus, Ethernet Controller 1.

Hi Uferdor,

Thank you for reply. So, if I configured as GPIO in RCW no needs to done any pin configuration and it will take automatically secondary function

Is it right?

Yes.
