problems while flsahing example code on esp-wroom-32

[benedito821]

Hello! I have migrated from PlatformIO plugin to ESP-IDF and I made all the configurations as shown in the Espressif article "get started". I use Ubuntu. The problem appears when I try to flash an example provided in the ESP repository (project "blink") : it gives back some errors. Here is my log:

esptool.py v3.1-dev
Serial port /dev/ttyUSB1
Traceback (most recent call last):
File "/home/benedito/.espressif/python_env/idf4.4_py3.6_env/lib/python3.6/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:

it builds normaly, only the flsahing. I have connected the board to the PC. I could I solve this?

Hi benedito821, please first make sure you are able to Establish Serial Connection with ESP32

Thanks. You were right. I just clicked on the button ESP-IDF select device port and choosed the port. Strange how it didn't work before.
