[HELP] Mac Issue: No such file or directory: '/dev/ttyUSB1'

[nathanw]

Hi there. Please help.

Setup:

1. Mac Catelina
2. ESP-IDF 4.0 (and I've tried 4.1)
3. Python 3.9
4. VSCode

When flashing my ESP-32 I receive the following FLASH error related to '/dev/ttyUSB1' (which is a linux port and I'm on mac):

Code: Select all

$ /Users/nathan/.espressif/python_env/idf4.0.2_py3.9_env/bin/python
esptool.py v2.8
Serial port /dev/ttyUSB1
Traceback (most recent call last):
  File "/Users/nathan/.espressif/python_env/idf4.0.2_py3.9_env/lib/python3.9/site-packages/serial/serialposix.py", line 322, in open
    self.fd = os.open(self.portstr, os.O_RDWR | os.O_NOCTTY | os.O_NONBLOCK)
FileNotFoundError: [Errno 2] No such file or directory: '/dev/ttyUSB1'

During handling of the above exception, another exception occurred:

serial.serialutil.SerialException: [Errno 2] could not open port /dev/ttyUSB1: [Errno 2] No such file or directory: '/dev/ttyUSB1'
The terminal process failed to launch (exit code: 1).

Terminal will be reused by tasks, press any key to close it.

I've installed everything from scratch numerous times now with no success.

- BUILDING works, just FLASH fails.
- Installed drivers (https://ftdichip.com/drivers/vcp-drivers/)
- And these drivers too (https://www.silabs.com/developers/usb-t ... cp-drivers)
- I can connect to the device (https://docs.espressif.com/projects/esp ... requisites) via:

Code: Select all

ls /dev/cu.*
/dev/cu.Bluetooth-Incoming-Port	/dev/cu.NathansAirPodRacers-Wir	/dev/cu.SLAB_USBtoUART		/dev/cu.SRS-XB10-CSRGAIA	/dev/cu.usbserial-0001

then run...

screen /dev/cu.SLAB_USBtoUART 115200

... (output from the esp32)

I've been trying to fix this one four almost an entire day and I'm losing my mind. Any help would be appreciated.

What is the command you are using to flash your program ?

If you are using the ESP-IDF extension for Visual Studio Code, make sure to use the ESP-IDF: Select port to use to choose the serial port before you flash as shown in the How to use

Otherwise if you are using the command line, You need to specify the port for example with idf.py flash -p port to make sure the port being used is the right one.

Dumb question, have you tried using ls /dev/tty* to see if linux has connected your drive as ttyUSB1?

Go through below link for better understanding:

And be specific like:
