General issue report

Hi

I am using esp-idf 5.1.2 and i followed the 'using-docker-container' tutorial. It is possible to build a project inside the docker, but i am not able to flash the binary to my device. The host os is windows 10.

Flashing fails with:

` * Executing task: /opt/esp/python_env/idf5.1_py3.8_env/bin/python /opt/esp/idf/components/esptool_py/esptool/esptool.py -p /dev/ttyUSB1 -b 460800 --before default_reset --after hard_reset --chip esp32 write_flash --flash_mode dio --flash_freq 40m --flash_size 2MB 0x1000 bootloader/bootloader.bin 0x10000 COM1xx.bin 0x8000 partition_table/partition-table.bin

esptool.py v4.7.dev3 Serial port /dev/ttyUSB1

A fatal error occurred: Could not open /dev/ttyUSB1, the port is busy or doesn't exist. ([Errno 13] could not open port /dev/ttyUSB1: [Errno 13] Permission denied: '/dev/ttyUSB1')

Hint: Try to add user into dialout group: sudo usermod -a -G dialout $USER

• The terminal process "/opt/esp/python_env/idf5.1_py3.8_env/bin/python '/opt/esp/idf/components/esptool_py/esptool/esptool.py', '-p', '/dev/ttyUSB1', '-b', '460800', '--before', 'default_reset', '--after', 'hard_reset', '--chip', 'esp32', 'write_flash', '--flash_mode', 'dio', '--flash_freq', '40m', '--flash_size', '2MB', '0x1000', 'bootloader/bootloader.bin', '0x10000', 'COM1xx.bin', '0x8000', 'partition_table/partition-table.bin'" terminated with exit code: 2. `

What can I try to resolve this?

Please see the note in the https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/tools/idf-docker-image.html#using-the-image-interactively section. Using remote serial port is a way to overcome this limitation on Windows.

Thanks, using the esp tool esp_rfc2217_server.exe it works.

Maybe the tutorial should be updated because this states it should work with usbipd: https://github.com/espressif/vscode-esp-idf-extension/blob/master/docs/tutorial/using-docker-container.md

This question is probably better located in vscode-esp-idf-extension repository.

Are you sure that the serial port was properly bind and attached to WSL with usbipd? You can use the ESP-IDF: Select port to use command to see available serial ports. I have tested it recently and it does work as long as the device was properly bind and attached.

Will add documentation using esp tool esp_rfc2217 for an alternative solution to usbipd.

Apologies for using the wrong repository.

The COM port seemed to be attached to WSL. (I checked it as proposed in the tutorial) But I think there is something wrong permission wise. I could not figure out what..
