A repo to house my linux kernel build code and setup instructions. As well as be an affordable web host for my rendered kernels.
My kernel build(s) are based upon the Ubuntu Server 20.04 available at
http://docs.linuxfactory.or.kr/install/prebuilt_image.html
And the kernel fork was sourced from
https://github.com/chewitt/linux/tree/amlogic-5.15.y (which is forked from Torvalds).
- I build on the native device. No cross-compilation used. I was simply too scared that adding a twist like cross-compilation would be yet another hole for me to fall into. So I made the decision to spend WAAAY longer compiling on-device, than get the quick compilation on a different architecture.
- I use an emmc module for storage on my N2Plus. I don't know if using an SD Card makes any difference at all, so, if it does... you've kinda been warned.
sudo apt install git build-essential bc flex bison libssl-dev libncurses-dev libelf-dev
sudo apt install nano tmux rsync
For Example: If you were wanting to make a 5.15 version build
git clone -b amlogic-5.15.y --depth 1 https://github.com/chewitt/linux
cd linux
# We are going to copy the preset configuration which was used to build the 5.13 kernel on the N2 . That way, all we have to do is to configure all of the optional modules which were made available since that build was released.
cp /boot/config-5.13.0-odroid-arm64 .config
# This next command allows us to set our new kernel's build name. This is very important, I'll explain later
sed -i "s/.*CONFIG_LOCALVERSION_AUTO.*/CONFIG_LOCALVERSION_AUTO=n/g" .config
# I don't actually think that this next instruction does anything at all, but it is at least harmless
echo "-odroid-n2-plus-arm64" > .scmversion
# Get ready to answer some yes/no questions about 'if this/that module/feature should be built/included'
make -j 6 LOCALVERSION="-odroid-n2-plus-arm64" oldconf
# Whew, that took some time, Let's get building.
make -j 6 LOCALVERSION="-odroid-n2-plus-arm64" modules amlogic/meson-g12b-odroid-n2-plus.dtb
# Prep the kernel flashing
sudo sed -i "s/^force=.*$/force=\"yes\"/g" /usr/share/flash-kernel/functions
# Prep the modules and the existing module libraries
sudo ln -s $PWD/arch/arm64/boot/dts /usr/lib/linux-image-$(cat include/config/kernel.release)
# Install the new modules
sudo make -j 6 LOCALVERSION="-odroid-n2-plus-arm64" modules_install
# Build the Kernel
make LOCALVERSION="-odroid-n2-plus-arm64"
# Install your new Kernel
sudo make installIf you want to redistribute your new kernel/modules/tweaks , then you can pack it all up very neatly with:
nice make -j 6 LOCALVERSION="-odroid-n2-plus-arm64" oldconfig modules amlogic/meson-g12b-odroid-n2-plus.dtb bindeb-pkg
