ESP32S3 OTA 调试记录
使用 ESP IDF框架进行开发，版本：V5.4.1
基于官方提供的模板 station_example 的示例代码，基于该基础的联网 wifi station 的示例
在原有的 app_main 函数中
点击查看代码
void app_main(void)
{
//Initialize NVS
esp_err_t ret = nvs_flash_init();
if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {
ESP_ERROR_CHECK(nvs_flash_erase());
ret = nvs_flash_init();
}
ESP_ERROR_CHECK(ret);
ESP_LOGI(TAG, "ESP_WIFI_MODE_STA");
wifi_init_sta();
}
增加代码如下：

esp_wifi_set_ps(WIFI_PS_NONE);//Ensure to disable any WiFi power save mode,
xTaskCreate(&simple_ota_example_task, "ota_example_task", 8192, NULL, 5, NULL);

注意点：
1、官方给的 OTA示例使用增加了这样一段处理代码：
esp_wifi_set_ps(WIFI_PS_NONE);//Ensure to disable any WiFi power save mode,
故而在进行 OTA 操作之前，需要禁用 wifi 低功耗操作
2、在升级的时候需要配置对应 http client 的config
config 中需要配置的 一个参数 .crt_bundle_attach = esp_crt_bundle_attach, 必须要配置
3、一定需要再 sdkconfig 中对 分区表进行配置，需要开启 OTA对应的分区
以及调整对应 flash 尺寸大小
