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なので OpenWrt の最新版との同期がとれるかをメモ。
OpenWrt which runs on the Atheros AR 9331 of Arduino Yun, LLC edition OpenWrt-Yun also Linino is obsolete in the kernel and various packages (and there are security problems).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''')

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).

OpenWrt which runs on the Atheros AR 9331 of Arduino Yun, LLC edition OpenWrt-Yun also Linino is obsolete in the kernel and various packages (and there are security problems).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

https://github.com/arduino/openwrt-yun-1505

Explore the Yun Profile of the OpenWrt / LEDE Project

The OpenWrt / LEDE Project, already exist a Arduino Yun Profile.

Arduino OpenWrt Yún packages: 

(y) avrdude *

  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.

Important concept of OpenWrt

The Minimized (smaller footprint) is Highest Priority. This is the large difference in policy between PC GNU/Linux and OpenWrt.

Trunk Bleeding Edge / Reboot version of OpenWrt-Yun package and build environment

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

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 

mkdir Build_Path_Some_Where
cd Build_Path_Some_Where
git clone --branch lede-17.01 https://github.com/openwrt/openwrt.git
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

memo memo... be careful 

setenv board Yun
setenv mtdparts "spi0.0:256k(u-boot)ro,64k(u-boot-env),15936k(firmware),64k(nvram),64k(art)ro"
setenv rootfstype "squashfs,jffs2"
setenv bootargs "console=ttyATH0,250000 board=Yun mem=64M"
setenv noinitrd


memo...

setenv serverip ‹tftp-server-ip›; setenv ipaddr ‹yun-board-ip›;
setenv serverip 192.168.1.10;
setenv ipaddr 192.168.1.1;
ping 192.168.1.10;

LininoIO OS upgrade from U-boot
Reflashing the OpenWrt-Yun image on the Yún
Restore the 1.5.3 image after you did sysupgrade to 1.6.2 on old Yún

Restore old image: 

setenv bootargs board=YUN console=ttyATH0,250000 mtdparts=spi0.0:256k(u-boot)ro,64k(u-boot env)ro,14656k(rootfs),1280k(kernel),64k(nvram),64k(art),15936k@0x50000(firmware) rootfstype=squashfs,jffs2 noinitrd
saveenv

CONFIG_ASH_HELP The default has been changed to 'n'.

Add a configuration of the AR9331 as AVR writer to the original package.
/etc/avrdude.conf

/etc/avrdude.conf:

  reset = ~18;
  sck   = 11;
  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'
	list alias '/mailbox=/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.

Bricked

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.
    • opkg_conf_parse_file: Duplicate src declaration
    https://wiki.openwrt.org/doc/techref/opkg
    https://wiki.openwrt.org/doc/packages
    Specification seems not yet settled.
  3. OOM
    (extroot environment)
    /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).
  4. sysupgrade with ExtRoot
    sysupgrade with ExtRoot :: wiki.mbirth.de
    sysupgrade ...
# reboot...
rm /mnt/sda2/etc/.extroot-uuid
reboot
#...
opkg update
opkg upgrade $(opkg list-upgradable | awk '($1 !~ "^kmod|Multiple") {print $1}')

    How can I reduce kernel size?
    It does not fit in 1280k.

    To find missing library provider, if the case is not obvious (usually it is just a library name), you may search in $STAGING_DIR/pkginfo folder.
