Yocto + SWUpdate + RaspberryPi3

Created: 2023/10/26

概要

SWUpdateをRaspberryPi3で試す。

Raspberry Pi3で試す

次の手順でイメージをビルドしSDカードに書き込んで起動を確かめます。

開発用コンテナを作成
各レイヤの取得
ビルド
書き込み

ビルド環境

Windows 11 + WSL + Docker

ターゲット

Raspberry Pi3
Yocto 4.0 (kirkstone)

Poky環境のセットアップ

$ mkdir rpi-kirkstone
$ cd rpi-kirkstone/
$ git clone -b kirkstone git://git.yoctoproject.org/poky.git
$ docker run --rm  -it  -v $(pwd):/workdir crops/poky --workdir=/workdir

コンテナ内のシェルで作業する。関連コマンドを有効にするためにスクリプトを実行する。

pokyuser@4c5ad0c1bea7:/workdir$ source poky/oe-init-build-env

ここまでやるとbuildにconfなどが生成される

rpi-mickledore/
┣ build/
┃ ┗ conf/
┃   ┣ bblayers.conf
┃   ┣ conf-notes.txt
┃   ┣ local.conf
┃   ┗ templateconf.cfg
┗ poky/

meta-raspberrypiの取得

bitbake-layers layerindex-fetchを利用してmeta-raspberrypiをPoky内に配置する。

pokyuser@8f2fb8eb82ec:/workdir/build$ bitbake-layers layerindex-fetch meta-raspberrypi
pokyuser@8f2fb8eb82ec:/workdir/build$ bitbake-layers show-layers

========================================================================================================

yoctobsp              /workdir/poky/meta-yocto-bsp                                            5
raspberrypi           /workdir/poky/meta-raspberrypi                                          9

meta-swupdate-boardsの取得

bitbake-layers layerindex-fetchを利用してmeta-raspberrypiをPoky内に配置する。

pokyuser@8f2fb8eb82ec:/workdir/build$ bitbake-layers layerindex-fetch meta-swupdate-boards

TODO: ちゃんと試す

local.confを編集

conf/local.confをVSCodeで編集

RPI_USE_U_BOOT = "1" を追加する。

# (中略) ...
MACHINE = "raspberrypi3-64"
DL_DIR = "${TOPDIR}/../downloads"

# enable uart
ENABLE_UART = "1"

# systemd
DISTRO_FEATURES:append = " systemd"
VIRTUAL-RUNTIME_init_manager = "systemd"
DISTRO_FEATURES_BACKFILL_CONSIDERED = "sysvinit"
VIRTUAL-RUNTIME_initscripts = ""

# Accept for the synaptics license
LICENSE_FLAGS_ACCEPTED = "synaptics-killswitch"

RPI_USE_U_BOOT = "1"

書き込み

bmaptoolsで書き込むのが良いが、Windows環境だと不自由なので解凍してRaspberry pi Imagerを利用して書き込む。

pokyuser@8f2fb8eb82ec:/workdir/build$ cd tmp/deploy/images/raspberrypi3-64/
pokyuser@8f2fb8eb82ec:/workdir/build/tmp/deploy/images/raspberrypi3-64$ cp core-image-base-raspberrypi3-64.wic.bz2 /workdir/
pokyuser@8f2fb8eb82ec:/workdir/build/tmp/deploy/images/raspberrypi3-64$ cd /workdir/
pokyuser@8f2fb8eb82ec:/workdir$ bunzip2 core-image-base-raspberrypi3-64.wic.bz2

Windows側にcore-image-base-raspberrypi3-64.wicを移動させ、カスタムイメージとして書き込む。
