无法找到 ESP8266 的设备路径

我正在尝试使用 esptool 将 MicroPython 刷入我的 ESP8266 芯片（使用这主板），而我在部署固件时遇到了困难（目前遵循MicroPython 文档）。

当我尝试查找 dev 路径时，ttyUSB 根本没有出现

tristan@tristan-Laptop:~$ ls /dev/tty.*
ls: cannot access '/dev/tty.*': No such file or directory
tristan@tristan-Laptop:~$ ls /dev/ttyUSB*
ls: cannot access '/dev/ttyUSB*': No such file or directory
tristan@tristan-Laptop:~$

这是我使用时的输出系统盘

tristan@tristan-Laptop:~$ lsusb
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 004: ID 27c6:609c Shenzhen Goodix Technology Co.,Ltd. Goodix USB2.0 MISC

我确定我的设备是 Silicon Labs CP210x UART Bridge，因此我尝试运行擦除闪存命令，/dev/bus/usb/003/014这是我的输出

tristan@tristan-Laptop:~$ sudo esptool.py --port /dev/bus/usb/003/014 erase_flash
esptool.py v4.1
Serial port /dev/bus/usb/003/014

    orig_attr = termios.tcgetattr(self.fd)
termios.error: (25, 'Inappropriate ioctl for device')

During handling of the above exception, another exception occurred:

答案1

跑步：

sudo apt remove brltty

然后重启电脑。对我来说，它成功了！
