Sharing: TP-Link AC600 Nano on Raspbian Bookworm 32-Bit

I figured this out, and I wanted to share how to do it.

Kernel headers are not (yet?) available on 32-bit v8. To get past this:

echo "arm_64bit=0" | sudo tee -a /boot/firmware/config.txt > /dev/null

Reboot
Either:

sudo apt --fix-broken install -y
sudo apt update
sudo apt full-upgrade -y
sudo apt autoremove --purge -y
sudo apt clean

curl -fsSL https://gist.githubusercontent.com/lbussy/23c05d8dc8c24d8d8edddf1d381f1c8b/raw/install_aliases.sh | bash

(this will pull down a .bash_aliases, run the above updates, and add some handy aliases. More in this Gist.)

Reboot (if indicated)
Install required packages:

sudo apt-get install dkms raspberrypi-kernel-headers

Clone repo:

git clone -b v5.6.4.2 https://github.com/aircrack-ng/rtl8812au.git
cd rtlrtl8812au

Change line in dkms.conf:

MAKE="ARCH=arm 'make' -j$PROCS_NUM KVER=${kernelver} KSRC=/lib/modules/${kernelver}/build"

or

sed -i 's/^MAKE="/MAKE="ARCH=arm\ /' dkms.conf

Update Makefile:

CONFIG_PLATFORM_I386_PC = n
CONFIG_PLATFORM_ANDROID_ARM64 = n
CONFIG_PLATFORM_ARM_RPI = y
CONFIG_PLATFORM_ARM64_RPI = n
CONFIG_PLATFORM_ARM_NV_NANO = n

or

sed -i 's/CONFIG_PLATFORM_I386_PC = y/CONFIG_PLATFORM_I386_PC = n/g' Makefile
sed -i 's/CONFIG_PLATFORM_ARM_RPI = n/CONFIG_PLATFORM_ARM_RPI = y/g' Makefile

Export environment:

export ARCH=arm

Make and install drivers:

sudo make dkms_install

Reboot
Bask in the glory of the wlan0 being available with ip link show:

$ ip link show
