Простейшая реализация SWUpdate на raspberry pi

Question

Пытаюсь сделать простейшее обновление ОС и кода приложения на Raspberry 3b.

Когда я пытаюсь использовать rauc, я застрял с загрузчиком. Так что я пытаюсь использовать SWUpdate по sbabic.

Я также старался следовать этим и другим инструкциям:

Инструкция № 1 по Danish Shrestha (я также судимый для использования версии, описанный в этой статье - Зевсой и bdc467d совершить версию меты-swupdate плата и я получаю тот же результат, что описанные далее)

Инструкция #2

Я сделал это:

git clone git://git.yoctoproject.org/poky -b dunfell
git clone git://github.com/openembedded/meta-openembedded.git -b dunfell
git clone https://github.com/agherzan/meta-raspberrypi.git -b dunfell
git clone https://github.com/sbabic/meta-swupdate -b dunfell    
git clone https://github.com/sbabic/meta-swupdate-boards.git -b master

Содержимое bblayers.conf:

POKY_BBLAYERS_CONF_VERSION = "2"    
BBPATH = "${TOPDIR}"
BBFILES ?= ""

BBLAYERS ?= " \

#For bitbake -c clean swupdate
#DISTRO_FEATURES += "systemd"

При этом я делаю:

bitbake -k update-image

И Raspberry напечатает это при запуске:
