The vendor kernel is based on the Rockchip 4.4 kernel with hardware support for ROCK Pi E. Below is how to build it on a X86 Linux host PC.

=== Get the kernel source ===

Branch release-4.4-rockpi4 supports ROCK Pi E board.

git clone -b release-4.4-rockpi4 https://github.com/radxa/kernel.git
cd kernel

=== Install toolchain from Linaro ===

wget https://releases.linaro.org/components/toolchain/binaries/7.3-2018.05/aarch64-linux-gnu/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu.tar.xz
sudo tar xvf gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu.tar.xz -C /usr/local/
export ARCH=arm64
export CROSS_COMPILE=/usr/local/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-

=== Build kernel===

make rockchip_linux_defconfig

If you need to build kernel modules that are not in the default config, you can select it in menu config

make menuconfig #(optional)

Now build it

make -j8

The built targets we are interested are '''arch/arm64/boot/Image''' and dtb file '''arch/arm64/boot/dts/rockchip/rk3328-rock-pi-e.dtb'''.

=== Build kernel deb package ===

The kernel package build can pack the kernel, device tree, modules and firmware into Debian packages, which makes it easier to install on the ROCK Pi E.

First, setup the version number, make sure the format is right.

export build_id="999" # make sure it's big enough so that our kernel is the newest.
export lv="-$build_id-rockchip"
export kv=$(make kernelversion)
export debv="$kv$lv"

make bindeb-pkg -j8 LOCALVERSION=$lv KDEB_PKGVERSION=$debv

The generated packages are(the kernel revision name maybe different):

<pre>
ls ../*.deb

../linux-firmware-image-4.4.154-999-rockchip-g8b7b311_4.4.154-999-rockchip_all.deb

../linux-libc-dev_4.4.154-999-rockchip_all.deb
</pre>

copy '''linux-image-4.4.154-999-rockchip-*_all.deb''' and '''linux-firmware-image-4.4.154-999-rockchip-*_all.deb''' to your ROCK Pi E.

==== Install it on ROCK Pi E.====

rockpie# dpkg -i linux-image-4.4.154-999-rockchip-*_all.deb linux-firmware-image-4.4.154-999-rockchip-*_all.deb

Reboot you will have the new kernel booting.
