Your faster way to startup a buildroot project

About

br-template is a set of Makefile rules and configurations files to easily setup a buildroot based project. It's a template: you can fork it and personalize it as you want.

What br-template offers:

Easy to use project structure: your files are under a br2-external tree so the don't mess with the main buildroot files
Buildroot is downloaded and extracted as is, so you can version only your files.
Easily generates an swu update files for swupdate

Building
  all                    - compiles everything
  image                  - produces images files in out/images
  update                 - produces an update swu file in out/update

Cleaning
  clean                  - removes everything but keeps dl folder
  distclean              - reset the project to a clean state
  withdocker             - builds using docker

Buildroot management

Recovery build fails withdocker option

I know this is very old so apologies. Commenting back in the recovery lines in br-template.config and building with "make withdocker all" yields this error:

make[1]: Leaving directory '/home/br-user/out/qemu_arm_versatile_custom'
BR2_DL_DIR=/home/br-user/out/dl BR2_JLEVEL=20 \
	make -C out/qemu_arm_versatile_custom_recovery source all
make[1]: Entering directory '/home/br-user/out/qemu_arm_versatile_custom_recovery'
for f in board/qemu/arm-versatile/linux-4.13.config ; do if [ ! -f "${f}" ]; then printf "Kconfig fragment '%s' for '%s' does not exist\n" "${f}" "linux"; exit 1; fi; done
make[2]: *** [linux/linux.mk:607: board/qemu/arm-versatile/linux-4.13.config] Error 1
Kconfig fragment 'board/qemu/arm-versatile/linux-4.13.config' for 'linux' does not exist
make[1]: *** [Makefile:23: _all] Error 2
make[1]: Leaving directory '/home/br-user/out/qemu_arm_versatile_custom_recovery'
make: *** [Makefile:51: image] Error 2
make: *** [Makefile:87: withdocker] Error 2

The qemu_arm_versatile_custom board images all seem to be built okay just prior.

Another question, do you have example files of how to achieve the update scheme you outlined in your Linuxlab Conf talk with a redundant bootloader and recovery partition? The "official" swupdate docs all point to a traditional A/B double copy scheme of just having a copy of rootfs. We'd like to update the entire system (including U-boot bootloader) and thus far your proposal sounds best but I am not sure how to implement it without a full example. Thanks!
