您好！
我是一个ESP32的新用家，我在用快速入门去安装ESP-IDF这个开发平台，我现在在用的是ESP32 DEVKIT V1 模块，OS 是Window 10. 我估计在连接ESP32 和 PC 时已有问题，
我在确认串口连接时，在PuTTY Configuration 选了 COM3， 115200 BAUD， 8 Data Bits， 1 Stop Bit， 按 Open 键时没有反应。
我改用了 Tera Term 时，便有以下的一大串信息在 Tera Term 上面打印出来

看起来好像是连接起来啦，然后我输入
cd ~/esp/hello_world
make menuconfig
把 Serial Flasher Config 里头设成为：
(/dev/ttyUSB0) Default serial port │ │
│ │ Default baud rate (115200 baud) ---> │ │
│ │ [*] Use compressed upload │ │
│ │ Flash SPI mode (DIO) ---> │ │
│ │ Flash SPI speed (40 MHz) ---> │ │
│ │ Flash size (4 MB) ---> │ │
│ │ [*] Detect flash size when flashing bootloader │ │
│ │ Before flashing (Reset to bootloader) ---> │ │
│ │ After flashing (Reset after flashing) ---> │ │
│ │ 'make monitor' baud rate (115200 bps) ---> │ │
│ └─────────────────────────────────────────────────────────────
然后输入：
cd ~/esp/hello_world
make flash
ESP-IDF 打印了一串新息如下，看起来好像是端口连接·有问题。

请问估计是哪里出现了问题，应该如何解决？
谢谢！
