Description:
Im working with example code ETH_LAN8720, and i get the following error as mentioned below.
The circuit connections are as follows:-
| GPIO | RMII Signal | ESP32 EMAC Function |
|---|---|---|
| 0 | REF_CLK | EMAC_TX_CLK |
| 21 | TX_EN | EMAC_TX_EN |
| 19 | TX0 | EMAC_TXD0 |
| 22 | TX1 | EMAC_TXD1 |
| 25 | RX0 | EMAC_RXD0 |
| 26 | RX1 | EMAC_RXD1 |
| 27 | CRS_DV | EMAC_RX_DRV |
| Default Example GPIO | RMII Signal |
|---|---|
| 23 | MDC |
| 18 | MDIO |
