Host Environment Variables:

ARM

export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf-

One line example:
export CROSS_COMPILE=arm-linux-gnueabihf- ARCH=arm

ARM64

export ARCH=arm64
export CROSS_COMPILE=aarch64-linux-gnu-

Optional: export KCFLAGS="$KCFLAGS -Wmaybe-uninitialized"

Kernel configuration:

make adi_bcm2709_defconfig
or
make adi_bcm2711_defconfig (for rpi4)
or
make adi_bcmrpi_defconfig (for rpi zero, zero W)
or
make zynq_xcomm_adv7511_defconfig (for Zynq)
or
make adi_zynqmp_defconfig (for ZynqMP)

Building the Kernel:

make -j4
or
make -j4 zImage modules dtbs (for rpi)
or
make -j4 UIMAGE_LOADADDR=0x8000 uImage (for Zynq)
or
make -j4 Image UIMAGE_LOADADDR=0x8000 (for ZynqMP)

Install modules:

sudo make modules_install
or
with path to rootfs: sudo make INSTALL_MOD_PATH=/media/amiclaus/rootfs/ modules_install

Copy the outputs

sudo cp arch/arm/boot/dts/*.dtb /media/amiclaus/BOOT/
sudo cp arch/arm/boot/dts/overlays/*.dtb* /media/amiclaus/BOOT/overlays/
sudo cp arch/arm/boot/dts/overlays/README /media/amiclaus/BOOT/overlays/
sudo cp arch/arm/boot/zImage /media/amiclaus/BOOT/$KERNEL.img

Replace $KERNEL.img with kernel7.img for Pi 2/3, kernel7l.img for Pi 4, kernel.img for Pi Zero/Pi Zero 2.

with scp: scp arch/arm/boot/zImage [email protected]:/boot/kernel7.img scp arch/arm/boot/dts/overlays/rpi-admv1014.dtbo [email protected]:/boot/overlays

Rpi mount:

ifconfig
mount /dev/mmcblk0p1 /media/boot/
