Hello everybody,
I tried to build the image using both scripts on wsl2 and got errors on the IDF setup.

Looks like it is missing a call to ./install.sh
only you need remove the hidden directory of your local machine of the IDF. Something like this:
rm -r ~/.espressif

Hi @jcmvbkbc
I tried your "wifi" script on WSL (Win 11) and got it to build successfully after resolving some missing dependencies.
I loaded the firmware images on a custom board I made with ESP32-S3 ("wroom-1" module, N16R8 variant) and it seems to work great!
As a quick benchmark, I ran a ping test (to Google server and to my PC on the LAN) and I got this results:
Pinging back from my Windows PC yields a min/avg/max = 10/77/138 ms
I also tried to see how much download speed I could get, by running "time wget" with a 1GB file and got around 435KiB/s (1e9 bytes in 37m22s). That's about 3.5Mbps!
That's not bad at all considering the amount of overhead involved.
During all these test I got a few messages with GFP_KERNEL ("page allocation failure") but the system never hanged or rebooted.
I have to say I'm quite impressed by what you achieved with this platform. Great work!
