> I am working with Buildroot, to flash an image on my STM32MP157C-DK2 I wanted to have Wi-Fi working it but I got this error:
> Successfully initialized wpa_supplicant nl80211: 'nl80211' generic netlink not found Failed to initialize driver 'nl80211' wlan0: Unsupported driver 'nl80211' FAIL
> I configure the interfaces and wpa_supplicant.conf files correctly normally. I don't know wthat that means but my configuration in the menuconfigand linux-menuconfigis right (I think). Does it maybe have something to do with my target machine (the STM in this case) ?

I'd suggest you make sure that CONFIG_NL80211 is compiled as built-in or module in the kernel inside the image.
if it is marked as module, make sure you modprobe it.

Dagg.
