Hi,
I want to connect the driver LAN8742 to ESP32 for the ethernet port.
Have I connected the right pins?
RMII_RXD0 to IO25
RMII_RXD1 to IO26
RMII_CRS_DV to IO27
RMII_MDC to IO23
RMII_TXD1 to IO22
RMII_TX_EN to IO21
RMII_TXD0 to IO19
RMII_MDIO to IO18
RMII_REF_CLK to IO0
thanks in advance.

Re: Ethernet connection pins
Those are the pins I connected my LAN8720 to and it works ok. Take care with GPIO0 to prevent it entering flash mode accidentally from the clock input though.

Re: Ethernet connection pins
Yes those are the correct pins. Care must be taken on GPIO0 to on startup to prevent it booting into flash mode thugh.
