ADI br2-external

This br2-external contains Buildroot configuration specific to ADI that cannot be mainlined. Generic support for ADI evaluation boards is implemented in the ADI Buildroot tree.

Getting Started

git clone --recurse-submodules https://github.com/analogdevicesinc/br2-external.git
cd br2-external/buildroot
make BR2_EXTERNAL="${PWD}/.." adi_sc598_ezkit_defconfig

Additional configuration is applied using Buildroot fragments:

support/kconfig/merge_config.sh .config \
    ../configs/buildroot.fragment \
    <ADI Configuration fragments>

ADI Configuration Fragments

• configs/buildroot.fragment
  • Configure Buildroot to speed up builds
• configs/debug.fragment
  • Enable debugging in U-Boot and the kernel
  • Build the kernel image with an embedded root filesystem to reduce complexity around writing and mounting a root filesystem from storage
• configs/bootstrap.fragment
  • Enable a minimal bootstrap / installer image.
  • Includes only the tools required to program boot media.
