1 week ago btw, I have just tested you branch in here. It builds properly, but requires prf.conf changes as suggested below:
CONFIG_WIFI=y
CONFIG_NET_L2_WIFI_MGMT=y
CONFIG_NET_L2_ETHERNET=y
CONFIG_NETWORKING=y
CONFIG_NET_DHCPV4=y
CONFIG_NET_IPV4=y
CONFIG_NET_TCP=y

I ran west update and it now points to commit 83958eb937d. Is that what you meant?

This does not contain CONFIG_WIFI_ESP32. According to the documentation, it seems to me that I need to enable this. Not doing this caused some other issues in trying to get wifi running on the board I mentioned.

You can add that, however, it is not needed. You have already enabled wifi in dts .overlay file. Then, Kconfig automatically adds that into build:
menuconfig WIFI_ESP32
bool "ESP32 SoC WiFi support"
default y
depends on DT_HAS_ESPRESSIF_ESP32_WIFI_ENABLEDAnyway, with the suggested prj.conf above, I was able to build the application.

Oh interesting. I found his warning while trying to make wifi work on this board. I guess my idea that it's related to CONFIG_WIFI_ESP32 not working was wrong then?

CONFIG_WIFI_ESP32=y causes Kconfig warning on wemos ESP32-S2 Lolin Mini related to MBEDTLS
Bug
Can't build simple wifi application for the Wemos ESP32-S2 Lolin Mini board due to KConfig error. There seems to be an error where KConfig finds MBEDTLS defined in
zephyr/soc/nxp/instead ofzephyr/soc/espressif.Reproduction steps
Code for reproduction can be found here: https://github.com/leriksen137/config_wifi_esp32_does_not_build.git This project has the same topology as the zephyr example application.
Follow Zephyr getting started.
See ESP32-S2 Lolin Mini why west
blobs fetch hal_espressifis run.Expected behavior
App should build without warnings.
Actual behavior
Example console output:
Note the reference to zephyr/soc/nxp in the warning message.
Troubleshooting
I confirmed the output file in "path/to/repo/config_wifi_esp32_does_not_build/build/zephyr/zephyr.dts" contains:
In an attempt to help Zephyr correctly resolve the definition of MBEDTLS I removed the
zephyr/soc/nxpdirectory. This causes a different error:Trying to add
CONFIG_0=ydoes not work.Severity
Severe. The project I'm working on can't be finished while this is unresolved.
