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OpenWrt which runs on the Atheros AR 9331 of Arduino Yun, LLC edition OpenWrt-Yun also Linino is obsolete in the kernel and various packages (and there are security problems).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 / Bleeding Edge)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.'''

OpenWrt which runs on the Atheros AR 9331 of Arduino Yun, LLC edition OpenWrt-Yun also Linino is obsolete in the kernel and various packages (and there are security problems).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)


Prepare for the Security update of OpenWrt-Yun, Arduino Yun Operating System. In the IoT ERA, I think it is a very important thing.

OpenWrt-Yun Chaos Calmer 15.05

RedSnake64's implementation can be found at Arduino Yun forum.

RedSnake64 edition OpenWrt-Yun: 

https://github.com/RedSnake64/openwrt-yun/tree/15.05
ChaosCalmer_v1.4
I tried it. 'mDNS' is not active, so I could not be accessed in '.local'.
Grasp that implementation. I decided to make Arduino Yun package that can be used in OpenWrt trunk Bleeding Edge.

RedSnake64 edition become Arduino LLC Official edition:

  1. avrdude: use a OpenWrt package. Configuration for the Arduino Yun should be placed in /etc/avrdude.conf.
  2. cpu-mcu-bridge: overlaps with OpenWrt yunbridge package. For compatibility use a Arduino package.
  3. cwiid: only RedSnake64 edition. cwiid is Nintendo Wii remote interface package, so should delete.
  4. node: If you want to run node.js, Should turn on MIPS FPU EMULATOR kernel config.
  5. node, node-serialport: use a OpenWrt package. so should delete.
  6. "-legacy" mean that the 0.9.x version.
  7. rng-tools: use a OpenWrt package. so should delete.
  8. v8m-rb: Not required, so should delete.

https://github.com/openwrt/openwrt.git
https://github.com/nxhack/openwrt-yun-build-extra

Setup repos: 

mkdir Build_Path_Some_Where
cd Build_Path_Some_Where
git clone https://github.com/openwrt/openwrt.git
git clone --depth=1 --branch master --single-branch https://github.com/nxhack/openwrt-yun-build-extra.git
cd openwrt
ln -s ../openwrt-yun-build-extra/* .

Or lede-17.01

git clone --depth=1 --branch lede-17.01 --single-branch https://github.com/nxhack/openwrt-yun-build-extra.git
cd openwrt
ln -s ../openwrt-yun-build-extra/* .


Please modify ./files/etc/opkg/distfeeds.conf

First Time, Setup cross compile build environment (ubuntu 14.04): 

./FIRST_SETUP_ubuntu_Trusty_Tahr.sh
Also run fine on 'Bash on Ubuntu on Widnows' ;)

Build: 

./build.sh

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).

ar71xx: move Arduino Yun to generic building code

To use the new partitioning, you need to update your U-Boot env in advance: 

setenv mtdparts "spi0.0:256k(u-boot)ro,64k(u-boot-env),15936k(firmware),64k(nvram),64k(art)ro"
setenv bootcmd "run addboard; run addtty; run addparts; run addrootfs; bootm 0x9f050000 || bootm 0x9fde0000"
saveenv

setenv board Yun

Should be started before the Yun original startup script "S49generate_new_gpg_key".
To enable rngd, add rngd section to /etc/config/system

BUSYBOX ASH HELP Banner disappear.
CONFIG_ASH_HELP The default has been changed to 'n'.

  mosi  = 27;
  miso  = 8;
;

BUSYBOX: telnet is disabled.
nc localhost 6571

PATH has changed.
CONFIG_TARGET_INIT_PATH="/bin:/sbin:/usr/bin:/usr/sbin" to CONFIG_TARGET_INIT_PATH="/usr/sbin:/usr/bin:/sbin:/bin"

uhttpd: SSL is forced.
option redirect_https '1'
/etc/config/uhttpd
enable openssl-util libustream-openssl
CONFIG_OPENSSL_WITH_COMPRESSION=y

uhttpd: Use URL alias handle. Do not apply alias patch.
/etc/config/uhttpd
Add to /etc/config/uhttpd
	list alias '/arduino=/cgi-bin/luci'
	list alias '/data=/cgi-bin/luci'

Procd button mechanism exists. triggerhappy is not required.
(triggerhappy use HID button mechanism, It depends on kmod-input-*)
(kmod-gpio-button-hotplug + procd buttons, Of course, smaller footprint)

Definitely enable MIPS_FPU_EMULATOR. (disabled by default config)
For reduce kernel size, change the kernel config.
 1. Limit the target architecture to MIPS 24Kc. AR933X, AR724X
 2. Limit the target board.
 3. Enable PCI. need for making various packages.

My Yún doesn't boot anymore! How can I restore it?

Load YunSerialTerminal to enable serial console. Unplug SD card . Press 'YUN RST' button.

  1. If the prompt is out && if the OS can operable.
    1. Enabling the network. 
      ifconfig IF IP
route add default gw somewhere
      Edit /etc/resolv.conf
    2. Bring the official sysupgrade image via SD card. 
      mkdir /mnt/sda1
mount -t vfat /dev/sda1 /mnt/sda1
  2. If you can operate the u-boot via YunSerialTerminal.
    1. https://www.arduino.cc/en/Tutorial/YunUBootReflash

TO DO

  1. uboot-linino
    Once the bootloader rewrite fails, I am afraid that completely become brick...
  2. /etc/opkg.conf, /etc/opkg/distfeeds.conf, /etc/opkg/customfeeds.conf
    Since the strange message came out, modified distfeeds.conf, It is correct to modify opkg.conf.

    /etc/opkg/distfeeds.conf : Limit repositories.
    /etc/opkg.conf : lists_dir ext /var/opkg-lists place not tmpfs. ex. lists_dir ext /usr/local/var/opkg-lists
    /etc/opkg.conf : Add 'option force_space'
    lists_dir ext /usr/local/var/opkg-lists
option tmp_dir /usr/local/var/tmp
option force_space
    Anyway, Do not place any objects to /tmp and /var (symlink of /tmp).
