how to set eth static ip

[1163167506]

hi all
I can use phy8720, run example of ESP, and get IP through DHCP.

But when I set up static IP, Ping is blocked.

my code

Code: Select all

    esp_err_t err;
    tcpip_adapter_init();
    
    esp_event_loop_init(eth_event_handler, NULL);

    eth_config_t config = DEFAULT_ETHERNET_PHY_CONFIG;
    config.phy_addr = CONFIG_PHY_ADDRESS;
    config.gpio_config = eth_gpio_config_rmii;
    config.tcpip_input = tcpip_adapter_eth_input;
    config.clock_mode = CONFIG_PHY_CLOCK_MODE;

#ifdef CONFIG_PHY_USE_POWER_PIN
    /* Replace the default 'power enable' function with an example-specific one
     that toggles a power GPIO. */
     printf("########%s()-%d\n",__FUNCTION__,__LINE__);
     config.phy_power_enable = phy_device_power_enable_via_gpio;
#endif
    
    tcpip_adapter_dhcpc_stop(TCPIP_ADAPTER_IF_ETH);
    tcpip_adapter_ip_info_t info;
	memset(&info, 0, sizeof(info));
	IP4_ADDR(&info.ip, 192, 168, 31, 188);
	IP4_ADDR(&info.gw, 192, 168, 31, 1);
	IP4_ADDR(&info.netmask, 255, 255, 255, 0);
	tcpip_adapter_set_ip_info(TCPIP_ADAPTER_IF_ETH, &info);

    esp_eth_init(&config);
    esp_eth_enable();
