Hello,
I am trying to assign a static IP address to the erthernet interface on my esp32. I am using the following code:
tcpip_adapter_ip_info_t ipInfo;
IP4_ADDR(&ipInfo.ip, 192,168,128,200);
IP4_ADDR(&ipInfo.gw, 192,168,128,100);
IP4_ADDR(&ipInfo.netmask, 255,255,255,0);
tcpip_adapter_set_ip_info(ESP_IF_ETH, &ipInfo);
When I run this, no IP addresses are set, and all the above parameters remain 0.0.0.0
Does anyone have any experience with this?

} else {
ESP_LOGE(TAG, "ETH interface inited not correct!");

Re: Assign a static IP address to the the ethernet Port
Hello,
I have the same problem, I cannot set static IP:
failed: esp_err_t 0x5001 (ESP_ERR_TCPIP_ADAPTER_INVALID_PARAMS)
I use ESP-IDF v4.0-dev-478-gdf61612 and ESP32 DevKit V1
I can see that function: tcpip_adapter_dhcps_stop can work stil only for TCPIP_ADAPTER_IF_AP:
Is my version too old? I work on the master branch.

Re: Assign a static IP address to the the ethernet Port
Make sure you are disabling the client (dhcpc). Your code is disabling the server (dhcps)

Re: Assign a static IP address to the the ethernet Port
This is working.
Put the code below: eth_netif = esp_netif_new(&cfg); in the cmd_ethernet.c file register_ethernet() function.

char* ip= "*.*.*.*";

esp_netif_ip_info_t info_t;
