Even if Buildroot doesn't fully handle packages like debian/OpenEmbbeded and will probably never do (), you can still generate a package for your custom application and use it to update it on field, thanks to opkg.
Install opkg on target
$ make menuconfig
Package Selection for the target ---> Package managers ---> [*] opkg
- reflash the rootfs on your APF
Generate a package for your app
- we assume that you already integrated your application in Buildroot and that buildroot/package/my_app/ is existing.
- create a "control" file that will describe your application for opkg (buildroot/package/my_app/opkg/control):
Package: my-app Version: 2.0.800 Description: My application Section: applications Priority: optional Maintainer: Me Architecture: arm Homepage: Source: Depends:
- add a new compile rule in buildroot/package/my_app/my_app.mk
MY_APP_PACKAGE_DIR = $(BUILD_DIR)/my_app_package define MY_APP_BUILD_CMDS mkdir -p $(MY_APP_PACKAGE_DIR)/CONTROL cp ./package/my_app/opkg/control $(MY_APP_PACKAGE_DIR)/CONTROL/ mkdir -p $(MY_APP_PACKAGE_DIR)/usr/local/bin cp -a $(@D)/my_app $(MY_APP_PACKAGE_DIR)/usr/local/bin sh ./package/opkg/opkg-build $(MY_APP_PACKAGE_DIR) $(BINARIES_DIR) endef
