ESP32S2 Wroom

[vishalkwaghmare]

Hi guys,
I'm facing this error after build. I'm not able to flash.
Can anyone help me in this regard?


esptool: error: argument --chip/-c: invalid choice: 'esp32s2beta' (choose from 'auto', 'esp8266', 'esp32', 'esp32s2', 'esp32s3beta2', 'esp32c3')
ninja: build stopped: subcommand failed.
[618/887] Building C object esp-idf/expat/CMakeFiles/__idf_expat.dir/expat/expat/lib/xmltok.c.obj
ninja: build stopped: subcommand failed.
ninja failed with exit code 1


Any suggestions?
Thanks in advance!

Hi vishalkwaghmare,

ESP32-S2 is supported from IDF v4.2. You are using IDF v4.1.

Hi Sir,
Thank you for your response, but I'm already using version 4.2.

According to the screenshot, you have probably downloaded IDF v4.2 and using the project from there but you are still building with IDF v4.1. Please examine the value of environment variable IDF_PATH.

Here is set of options for set-target in v4.2, you can compare with yours:

Code: Select all

Usage: idf.py set-target [OPTIONS] [esp32|esp32s2]

Hi Sir,

Yes, you are right I was using the codebase from v4.2 but the ESP-IDF is of v4.1. I tried with v4.2 but it is showing some error in installation.
However, I'm able to run it with the master branch of ESP-IDF, here is the screenshot attached.

Thank you again for your support.
