On a x86/x64-host you need cross compile tools for the armhf architecture (bison and flex-package are needed for kernels >=4.16):
sudo apt install gcc-arm-linux-gnueabihf libc6-armhf-cross u-boot-tools bc make gcc libc6-dev libncurses5-dev libssl-dev bison flexIf you build it directly on the BananaPi-R2 (not recommended) you do not need the crosscompile-packages gcc-arm-linux-gnueabihf and libc6-armhf-cross
./build.sh importconfig
./build.sh config (To configure manually with menuconfig)
./build.shThe Dockerfile in utils/docker/ provides a build environment without installing the native compilers on the local system.
The local directory will be mounted into the docker container. All changes will also be present in the respository folder.
- Build the docker container for building once:
sh ./utils/docker/build_container.sh
- Start and connect to the running docker container:
sh ./utils/docker/run.sh
- Now you can use the commands from above:
./build.sh
- Close the container with
exitorCTRL-D. - Your build artifacts from the build script will be in the folder
./SD/
If you want to clean up you can remove all containers (and the associated docker images) with:
docker rmi bpi-cross-compile:1 --forceKernel upstream + BPI-R2

(Testing in seperate branch wlan/hdmi/hwnat/hwqos)
- HW-NAT only works on 4.14 between LAN and WAN (bridge unclear, wifi not supported)
- HW-QoS is merged into 4.14-main, but we do not know how to test it
- ACPI-feature means System is powered off, not only halted (power-consumption ~0.2W, no reboot on reset), reboot-problem with soldered power-switch (see frank-w#35). Power-off is also initiated by pressing the power-switch
- VIDEO is hdmi-output (X-server/framebuffer-console)...here some resolutions are not supported by vendor-driver
kernel 4.4 / uboot (2014-04): https://github.com/frank-w/BPI-R2-4.4
4.4-main does not contain drivers for r2 yet because this is too much work to merge it
