Hello all! I’ve got a Pocket Beagle running “Linux beagle bone 4.9.83-ti-r104 #1 SMP PREEMP”, I would like to change the kernel configuration to include support for the Realtek RTL8821AE WiFi driver. I see the option to load the driver in the Network Device Support section of the kernel config menu, but I am not able to compile the kernel using the normal Debian steps. I have installed “linux-headers-4.9.83.ti-r104” in “/usr/src”, and am able to get the config menu by running “make menuconfig” from in that directory. However, when I try to compile the kernel with “make all”, I get the following error:
debian@beaglebone:/usr/src/linux-headers-4.9.83-ti-r104$ sudo make all
scripts/kconfig/conf --silentoldconfig Kconfig
CHK include/config/kernel.release
CHK include/generated/uapi/linux/version.h
CHK include/generated/utsrelease.h
make[1]: *** No rule to make target ‘arch/arm/tools/gen-mach-types’, needed by ‘include/generated/mach-types.h’. Stop.
arch/arm/Makefile:320: recipe for target ‘archprepare’ failed
make: *** [archprepare] Error 2
debian@beaglebone:/usr/src/linux-headers-4.9.83-ti-r104$ sudo make menuconfig
scripts/kconfig/mconf Kconfig
*** End of the configuration.
*** Execute ‘make’ to start the build or try ‘make help’.
I am not able to get “make clean” to work, so I suspect I’m not doing it right. This is what I see:
make clean
[sudo] password for debian:
scripts/Makefile.clean:14: drivers/gpu/drm/nouveau/Makefile: No such file or directory

Is there a tutorial somewhere on how to compile the kernel from the headers after changing the kernel configuration? Does anyone have any thoughts?
Thanks,
Joe
