Target: OrangePi One H3 (AllWinner) armhf, .deb only for a specific board
Install crossbuild packages for the target architecture.
Install kernel sources
Move to your working dir & copy kernel sources.
Expand kernel sources
Move to sources dirIf you have patches to apply then copy them into linux-source-X.X folder and then for each patch do: Into arch/arm/ there are all supported boards, choose your board (mine is OrangePi One and it's a sunxi board)
Prepare for configuration, start with a minimum configurationsNow, we probably need more modules because that defconfig is a very minimal configuration Choose your modules. * In General Setup -> Stack Protector buffer overflow detection set it to None (or build will fail).
Build!Don't forget to set the target LOCAL_VERSION=-YOUR_TARGET_ARCH (ie: -arm-antani-lpae ), otherwise dpkg will not install the kernel. This is what i did for my OrangePi One: Wait until build process completes; ready to use .debs are in the upper level folder.
