Cannot get IP

[gpezzella]

Hello

our board is similar to OLIMEX ESP32-EVB. It use LAN8710 chip
The problem is that we cannot receive IP

Output log on ESP32-EVB is:

Code: [Select all] [Expand/Collapse]

1. TYPE LAN8720 OK
2. INITIALIZED OK
3. ENABLED OK
4. ETH Started Event raised
5. ETH Connected Event raised
6. ETH GOT IP Event raised
7. ETH MAC: 24:0A:C4:9E:F0:3F, IPv4: 10.0.30.92, FULL_DUPLEX, 100Mbps

On Emac_RXD1 pin I can see signal
I would change original code line for LAN8720:

Code: [Select all] [Expand/Collapse]

1. extern const eth_config_t phy_lan8720_default_ethernet_config;

with new one for LAN8710 but I don't know how to do.
I have found this OLIMEX code but it not compile.
Could you help me?
Thanks
