This repository contains documentation, tools, and build recipes to create WPE packages for RPi devices, in the form of directory ready to use with BR2_EXTERNAL.

Chose the appropriate “defconfig” for the target device (see list of included configurations below), and execute the following from the top-level Buildroot source tree directory:

make BR2_EXTERNAL='path/to/buildroot-wpe' raspberrypi3_wpe_rdk_defconfig
make BR2_EXTERNAL='path/to/buildroot-wpe'

This will download the needed sources, configure Buildroot, compile WPE, and store the build results under the output/ subdirectory.

To tune your build configuration use:

make BR2_EXTERNAL='…' menuconfig

Buildroot does not attempt to automatically detect what you have changed on the build config from the previous build. So if you are unsure about what sould be rebuilt after a build config change or how to do that, then trigger a complete new build from a clean state:

make BR2_EXTERNAL='…' clean
make BR2_EXTERNAL='…'

• raspberrypi2_wpe_defconfig: Produces an 1GB image file at output/images/sdcard.img for the Raspbrry Pi 2 with WPE. The image should be written to a SD card using a tool like dd or etcher.

• raspberrypi3_wpe_defconfig: Produces an 1GB image file at output/images/sdcard.img for the Raspberry Pi 3 with WPE. The image should be wrote raw to the sdcard, using a tool like dd or etcher

• raspberrypi3_wpe_rdk_defconfig: Produces an 512MB image file at output/images/sdcard.img for the Raspberry Pi 3 with WPE woth WpeBackend-RDK and RPI-UserLand. The image should be wrote raw to the sdcard, using a tool like dd or etcher

• Buildroot's BR2_EXTERNAL.
