Initializing WiFi in QEMU crashes the application (IDFGH-14296)

[szekelyisz]

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.

v5.5-dev-1050-gb5ac4fbdf9

Espressif SoC revision.

More Information.

The hello_world example works fine in qemu.

[o-marshmallow]

Hello @szekelyisz ,

You won't be able to run the Wifi examples since wifi is not supported in our QEMU fork. For networking, we implement an ethernet driver that can be enabled in ESP-IDF in the menuconfig via the option Support OpenCores Ethernet MAC (for use with QEMU).

Also, please note that we have another repository for QEMU issues: https://github.com/espressif/qemu/issues/

[szekelyisz]

Thanks @o-marshmallow I will try that. I think this should be mentioned in the docs, but that's another story.
