OpenWrt running on Atheros AR9331 of Arduino Yun, LLC edtion OpenWrt-Yun also Linino, is in obsolete (and has secutiry issues) at kernel and various packages. I will try to investigate the upgrade to the latest version of OpenWrt. (With Absolutely NO Warranty)
OpenWrt which runs on the Atheros AR 9331 of Arduino Yun, LLC edition OpenWrt-Yun also Linino is obsolete in the kernel and various packages (and there are security problems). I will drill down on how to upgrade to the latest version of OpenWrt. ('''With Absolutely NO Warranty''')




Arduino Yun の Atheros AR9331 で稼働する OpenWrt が、LLC 版 OpenWrt-Yun も Linino もカーネルやパッケージが古くていろいろ残念。 OpenWrt の最新版(trunk)との同期がとれるかを実験する 。つまり Arduino Yun の Atheros AR9331 のオペレーティングシステム(OS)である OpenWrt-Yun のセキュリティバージョンアップに順次対応できるように準備する。
Prepare for the Security update of OpenWrt-Yun, Arduino Yun Operating System. '''In the IoT ERA, I think it is a very important thing.'''

#avrdude は純正パッケージがある。Yun 用に設定された avrdude.conf があれば良い。avrdude.conf は ./files に配置する。
#avrdude: use a OpenWrt package. Configuration for the Arduino Yun should be placed in /etc/avrdude.conf.
#cpu-mcu-bridge は純正パッケージの yunbridge と重なるが互換性をかんがえるとこっちにする。(あとで yunbridge を動作検証する)
#cpu-mcu-bridge: overlaps with OpenWrt yunbridge package. For compatibility use a Arduino package.
#cwiid は RedSnake64 版のみだし Nintendo Wii remote interface なので削除する。
#cwiid: only RedSnake64 edition. cwiid is Nintendo Wii remote interface package, so should delete.
#node は純正パッケージで。
#node: '''If you want to run node.js, Should turn on MIPS FPU EMULATOR kernel config.'''
#node-serialport は純正パッケージでエラーがでるのでこっちに取り込む。純正 node-arduino-firmata も同様なので取り込む
#node, node-serialport: use a OpenWrt package. so should delete.
#:もし、純正モジュールで稼働するなら不要。y ではないので m する必要はなく n でよい。しかし現状は純正モジュールが build 失敗しているようで ipk が配布されていないようだ。安定するまでは m で。
#"-legacy" mean that the 0.9.x version.
#::当面は arduino packages で取り込む方針にする。
#rng-tools: use a OpenWrt package. so should delete.
#"-legacy" は 0.9.x 版という意味。間違えて Makefile 変えてしまった。忘れないように。
#v8m-rb: Not required, so should delete.
#rng-tools は純正パッケージは問題あり。
 
#:START=98 から START=48 にしないと Yun 独自の起動スクリプト S49generate_new_gpg_key で不具合がでる。これより前に rngd を起動する必要がある。
'''My new arduino packages here''':
#:純正パッケージの rngd.init にパッチあててから build させる方針にする。

git clone https://github.com/openwrt/openwrt.git

cd openwrt

Please modify ./files/etc/opkg/distfeeds.conf
 
First Time, Setup cross compile build environment (ubuntu 14.04):
<syntaxhighlight lang="bash" enclose="div">
./FIRST_SETUP_ubuntu_Trusty_Tahr.sh
</syntaxhighlight>
:Also run fine on 'Bash on Ubuntu on Widnows' ;)
 
Build:
<syntaxhighlight lang="bash" enclose="div">
./build.sh
</syntaxhighlight>
 
When build succeed, You find '''lede-ar71xx-generic-yun-16M-squashfs-sysupgrade.bin''' in ./bin/targets/ar71xx/generic directory.
:(Apply Yun-Shield patch, then SELECT Yun Shield: '''lede-ar71xx-generic-yun-shield-squashfs-sysupgrade.bin''')
 
In order to using the packages, You must placed kernel packages and arduino packages to server (or SD card).
