3年前能用,但现在连接不上了
CH340是盗版的,电脑驱动现在不兼容了
用外部usb转串口连esp8266 引脚上, 或在linux环境用
在 linux 环境用
bash
sudo apt install minicom
minicom -D /dev/ttyUSB0 -b 115200
# CTRL+ C 进交互
# CTRL+ D 进软重启
# CTRL+D X 退出minicom

# 安装esptool
pip3 install esptool或者
bash
sudo apt update
sudo apt install esptoolesptool命令
bash
minglie@minglie:~$ esptool --help
用法：esptool [-h] [--chip {auto,esp8266,esp32}] [--port 端口] [--baud 波特率]
[--before {default_reset,no_reset}]

esptool.py v2.1 ------ ESP8266 芯片ROM引导加载工具
位置参数（子命令）：
{load_ram,dump_mem,read_mem,write_mem,write_flash,run,image_info,make_image,elf2image,read_mac,chip_id,flash_id,read_flash_status,write_flash_status,read_flash,verify_flash,erase_flash,erase_region,version}
执行 esptool 子命令 -h 可查看该命令更多帮助
load_ram 将固件镜像下载到内存并运行
dump_mem 将任意内存内容导出保存到磁盘
read_mem 读取任意内存地址的数据
write_mem 对任意内存地址执行读‑修改‑写操作
write_flash 把二进制固件写入闪存（烧录固件）
run 运行闪存里的应用程序
image_info 打印应用固件镜像的头部信息
make_image 通过二进制文件生成应用固件镜像
elf2image 将ELF编译文件转为烧录用固件镜像
read_mac 从OTP只读存储器读取MAC地址
chip_id 从OTP只读存储器读取芯片ID
flash_id 读取SPI闪存的厂商ID与设备ID
read_flash_status 读取SPI闪存状态寄存器
write_flash_status 写入SPI闪存状态寄存器
read_flash 读取SPI闪存全部内容
verify_flash 将二进制文件和闪存内数据做校验比对
erase_flash 对SPI闪存执行整片擦除
erase_region 擦除闪存的某一段区域
version 打印esptool工具版本
可选参数：
-h, --help 显示帮助信息并退出
--chip {auto,esp8266,esp32}, -c {auto,esp8266,esp32}
指定目标芯片型号
--port 端口, -p 端口 串口设备路径（例如 /dev/ttyUSB0）
--baud 波特率, -b 波特率
烧录、读取时使用的串口波特率
--before {default_reset,no_reset}
连接芯片之前执行的操作
--after {hard_reset,soft_reset,no_reset}, -a {hard_reset,soft_reset,no_reset}
esptool执行完成之后执行的操作读mac地址
