I am working on Renesas RZ/G1M board (Yacto1.6 Daisy). I worte a recipe for rtl88121u module and I am able to compile module and insmod without any errors.
ifconfig is listing wlan0 interface but when I do iwconfig it's not showing any wlan0 interfaces. Following is the log of iwconfig and ifconfig.
wlan0 no wireless extensions.

Thanks and Regards,
For RZ/A, I have used this one in the past for the 8188:
Anyway, what I noticed is that in order to get it to work, I had to add "select WIRELESS_EXT" to the Kconfig.
Otherwise the wireless extensions driver in the kernel would not get built. There is no user menuconfig option
to enable WIRELESS_EXT, it must be forcible set by a driver Kconfig.
So, maybe you can try this:
config RTL8821AU tristate "Realtek 8821 USB WiFi" depends on USB+ select WIRELESS_EXT ---help---Help message of RTL8821AU
I think other users normally don't have an issue because their kernels
select lots of wireless chips to build so at least one of them will have
it set. But in my case, we want a minimum build, so we only enable this
one device, when is why I was seeing the issue but no one else.
Also, in "include/autoconf.h", I made this change:
diff --git a/include/autoconf.h b/include/autoconf.hindex f62231b..57bcd3c 100755--- a/include/autoconf.h+++ b/include/autoconf.h@@ -102,7 +102,7 @@ #define CONFIG_HOSTAPD_MLME 1 #endif #define CONFIG_FIND_BEST_CHANNEL 1- //#define CONFIG_NO_WIRELESS_HANDLERS 1+ #define CONFIG_NO_WIRELESS_HANDLERS 1 #endif
