esptool crush while trying to use remote connection via RFC2217

[gost.404]

Hi everyone!
I'm trying to work with ESP32 via remote serial port.
I have next chain: ESP32 -> USB-UART -> Orange Pi Zero -> my PC

On Orange Pi Zero I run rfc2217_serial.py script:

Code: Select all

python rfc2217_serial.py -p 4000 /dev/ttyUSB0

On my PC I launch esptool:

Code: Select all

esptool.py --port rfc2217://ip_address:4000 flash_id

And here what I've got:

Code: Select all

Traceback (most recent call last):
  File "/usr/local/bin/esptool.py", line 2849, in <module>
    _main()
  File "/usr/local/bin/esptool.py", line 2842, in _main
    main()
  File "/usr/local/bin/esptool.py", line 2543, in main
    esp = ESPLoader.detect_chip(each_port, initial_baud, args.before, args.trace)
  File "/usr/local/bin/esptool.py", line 244, in detect_chip
    detect_port = ESPLoader(port, baud, trace_enabled=trace_enabled)
  File "/usr/local/bin/esptool.py", line 224, in __init__
    self._port.write_timeout = DEFAULT_SERIAL_WRITE_TIMEOUT
  File "/usr/lib/python2.7/dist-packages/serial/serialutil.py", line 325, in write_timeout
    self._reconfigure_port()
  File "/usr/lib/python2.7/dist-packages/serial/rfc2217.py", line 491, in _reconfigure_port
    raise NotImplementedError('write_timeout is currently not supported')
NotImplementedError: write_timeout is currently not supported

Any ideas?
