一、烧录参数资料
1、模式选择：
2、确保 ESP32 模组正确的进入了下载模式： 1. 首先确保模组可以正常运行工作（即确保电源和串口连接正常）；2. 拉低 GPIO0，打开串口工具，在波特率115200下观察模组的启动或复位后的打印信息；3. 若出现以下红色字符则认为模组已经进入了下载模式，可以去正常进行下载。 rst:0x10 (RTCWDT_RTC_RESET),boot:0x3 (DOWNLOAD_BOOT(UART0/UART1/SDIO_REI_REO_V2)) waiting for download
3、ESP32 烧录地址及烧录文件： ESP32 在编译时，通过 make menuconfig 来配置 Partition Table 分别支持 Single factory app, no OTA、Factory app, two OTA definitions、Custom partition table CSV 注意1：乐鑫在不同版本的 SDK 中有可能会改变这些烧录位置，以 Console 输出信息为准。 注意2：合并后的固件内已经包含了地址信息，只需烧写到 0x0 地址即可。
app_demo.bin 和 partitions_singleapp.bin 在项目文件夹 hello_world/build 下：
bootloader.bin 在项目文件夹 hello_world/build/bootloader 下：

2、进入图形界面进行参数配置 设置串口和烧录参数
3、按照构建menuconfig菜单，再配置个下载选项
4、IDE右边框双击对应的Target可以执行

问题解决： 图形配置界面有问题，这里需要填windows下的串口号
