昔の Linux ボードの OS を更新する(Edison 編)
Linux つながりで、昔買って積みボードと化している Intel Edison の FW を更新してみたいと思います。
現状
ぶっちゃけほぼ初期状態です。 u-boot

イメージの Build
Intel Edison Image Builder を参考にします。
Build 環境に Ubuntu 22.04 (か 23.10)が必要なようなので、環境を用意します。 なお、ディスクの空き容量が 80GB 近く必要です。
$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat cpio python2 python3 libsdl1.2-dev xterm
$ sudo apt-get install p7zip-full btrfs-progs lz4
$ sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 1
$ sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 2
$ sudo update-alternatives --config python
[ 1 を選んで python2 をデフォルトにする]
git で build に必要なファイルを取得します。
$ mkdir my_Edison_Workspace
$ cd my_Edison_Workspace
$ git clone https://github.com/edison-fw/meta-intel-edison.git
$ ln -s meta-intel-edison/utils/Makefile.mk Makefile
$ cd meta-intel-edison
$ git checkout master
$ cd ..
$ make setup
Build する
$ cd out/linux64
$ source poky/oe-init-build-env
$ bitbake -k edison-image
かなり待ちます…。 私の環境では一晩かかりました。
$ cd ../..
$ make image
またちょっと待ちます。(1時間くらい？) フラッシュ書き込み用のイメージを作ります。
$ make postbuild
書き込み
out/current/build/toFlash にファイル一式があるので、書き込みツールで書き込みます。
dfu-utilをダウンロードして、インストールしておきます。
あとは root で flashall.sh を実行するだけです。
# ./flashall.sh
Using U-Boot target: edison-blankcdc

ほとぼりが冷めたら再起動します。 なお、Windows の Platform Flash Tool Lite でも書き込みできるはずのですが、私の環境では書き込みできませんでした。

と思ったらプロンプト来ました。初回起動時になにか処理している模様です。 次回からは普通に起動しました。
というわけで、お疲れ様でした。
