Answers checklist.

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

IDF version.

v5.3.2.

Espressif SoC revision.

ESP32 C6

Operating System used.

macOS

How did you build your project?

Command line with idf.py

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

None

Development Kit.

ESP32 C6 mini u1

Power Supply used.

USB

What is the expected behavior?

I expect to be able to run the SOFT AP example from: https://github.com/espressif/esp-idf/tree/v5.3.2/examples/wifi/getting_started/softAP

and it should work as documented.

What is the actual behavior?

I enter some kind of boot loop, whenever wifi is started usb connection is lost.

Steps to reproduce.

  1. Obtain hardware, I used: https://www.espressif.com/sites/default/files/documentation/esp32-c6-mini-1_mini-1u_datasheet_en.pdf in form of a LilyGo T-Knob
  2. Flash the example https://github.com/espressif/esp-idf/tree/v5.3.2/examples/wifi/getting_started/softAP or anything that needs wifi.
  3. Connect the monitor
