ESP32-WROVER-B; ethernet ota; return https read error -80/-76

[harry_wei]

Hi, Sir:

I added OTA features to my esp32 project and have some problems:
When I use WiFi sta mode, OTA (I refer to and migrate the code which is esp / ESP IDF / examples / system / OTA / simple_ota_example) works well; however, when I use Ethernet mode, esp_https_ota always returns an error "0x1503" (ESP_ERR_OTA_VALIDATE_FAILED);The detailed output log is as follows:

I don't know why. My hardware is ESP32-Ethernet-Kit_A_V1.1(ESP32-WROVER-B + IP101), and my IDF version is ESP-IDF v4.0-beta1-180-ga21eb04cc.I have installed the Ethernet driver correctly and got the local IP (DHCP succeeded); my eth code:

Code: Select all

static void  initialise_eth(void)
{
      ESP_LOGI(TAG, "init eths"); 
      ESP_ERROR_CHECK(tcpip_adapter_clear_default_wifi_handlers());
      ESP_ERROR_CHECK(tcpip_adapter_set_default_eth_handlers());
      ESP_ERROR_CHECK(esp_event_handler_register(ETH_EVENT, ESP_EVENT_ANY_ID, &eth_event_handler, NULL));     
      ESP_ERROR_CHECK(esp_event_handler_register(IP_EVENT, IP_EVENT_ETH_GOT_IP, &eth_ip_event_handler, NULL));
      eth_mac_config_t mac_config = ETH_MAC_DEFAULT_CONFIG();
      eth_phy_config_t phy_config = ETH_PHY_DEFAULT_CONFIG();
      esp_eth_mac_t *mac = esp_eth_mac_new_esp32(&mac_config);
      esp_eth_phy_t *phy = esp_eth_phy_new_ip101(&phy_config);

      esp_eth_config_t config = ETH_DEFAULT_CONFIG(mac, phy);
      esp_eth_handle_t eth_handle = NULL;
      ESP_ERROR_CHECK(esp_eth_driver_install(&config, &eth_handle));      
}

my ota code:

Code: Select all

         esp_http_client_config_t config = {
                  .url = ota_url,
                  .port = configure_using->ota_info.rport,
                  .cert_pem = (char *)server_cert_pem_start,
                  .event_handler = _http_event_handler,
                  .transport_type = HTTP_TRANSPORT_OVER_SSL,
                  .buffer_size = 4096,
                  .buffer_size_tx = 1024
            };
            
            esp_err_t ret = esp_https_ota(&config);
            if (ret == ESP_OK) {
                  ESP_LOGE(TAG, "Firmware Upgrades success");
                  task_delay(100);
                  esp_restart(); 
            } else {
                  ESP_LOGE(TAG, "Firmware Upgrades Failed %d, 0x%08X", ret, ret);
            }

Hi harry,

This issue is usually related to the HTTP server truncating the image.

HI,

I have solved this problem. There should be a problem with the default settings of ESP IDF.

Thanks！

How you solved the problem?
