Answers checklist.

• [X] I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• [X] I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• [X] I have searched the issue tracker for a similar issue and not found a similar issue.

IDF version.

v5.1

Operating System used.

Linux

How did you build your project?

Command line with idf.py

If you are using Windows, please specify command line type.

None

What is the expected behavior?

It must be possible to flash ESP32-C3 chip if the target is set to esp32c3.

What is the actual behavior?

esptool outputs:

A fatal error occurred: This chip is ESP32 not ESP32-C3. Wrong --chip argument?

Steps to reproduce.

The board is Wemos C3 Pico. You can see the chip is ESP32-C3:

1. idf.py create-project newproject
2. idf.py set-target esp32c3
3. idf.py -p /dev/ttyUSB0 --baud 115200 flash

sdkconfig

More Information.

I tried esptool chip_id and it says the chip is ESP32-PICO-D4. See auto.txt.

When running with --chip esp32c3: A fatal error occurred: This chip is ESP32 not ESP32-C3. Wrong --chip argument? See esp32c3.txt.

I have realized I also had another ESP device plugged in the USB hub, so the message is correct 😬 I'm sorry for the hassle.
