obs600-12 DIPSW1_OFFの_cf_boot

いままで、DIPSW1_ONでPROMPTで停止し、手入力でbootmコマンドで起動させていました。もっといい方法があるような気もしますが、以下のようにしてbootm f8000000 を組み入れています。良く無い例かもしれません。が、メモとして残します。(1)〜(6)は事前調査です。
(1)bootcmd は _boot_sel
bootcmd=echo;echo Run Boot Selection Script;echo;run _boot_sel;

(2)_boot_sel は run _phase_1
_boot_sel=run _phase_1

(3)DIPSW1_OFF で _phase_2_1
_phase_1=if get_dip 1;then echo *** SW 1 IS OFF ***;echo;run _phase_2_1;else echo *** SW 1 IS ON ***;echo;
run _phase_2_2;fi

(4)_phase_2_1　DIPSW2_OFF で _phase_3
_phase_2_1=if get_dip 2;then echo *** SW 2 IS OFF ***;echo;run _phase_3;else echo *** SW 2 IS ON, DOWNLOAD
 STANDARD OS ***;echo;run os_load_prog;fi

(5)_phase_3　DIPSW3_ON で _cf_boot
_phase_3=run _initsw_sel;if get_dip 3;then echo *** SW 3 IS OFF, Standard Boot ***;echo;run ${_std_script};
else echo *** SW 3 IS ON, Boot from CF ***;echo;run _cf_boot;fi

(6)_cf_boot はこのように定義されている
_cf_boot=usb start;echo;echo Loading ...;${cf_fs}load usb ${usbdev} ${_kernel_addr_r} ${_cf_bootfile};
if test x$filesize = x ; then ${cf_fs}load usb ${usbdev} ${_kernel_addr_r} ${_cf_bootfile_alt}; fi;usb stop;
 run _cfargs _addtty _show_bootargs;bootm ${_kernel_addr_r}

(6)’_cf_boot を以下の一行に書き換える
_cf_boot=echo;echo NKBMobile_20110919 Booting...;echo; bootm ${_kernel_addr}

-------------------------------------------------------------------------
＃ 本当はU-Bootプロンプトで以下のように書き換えたかったのですが、
＃ 変数名_cf_bootのように'_'で始まると、どうもsetenvできませんでした。
=> setenv _cf_boot "bootm f8000000"
## Error: illegal character '_' in variable name head "_cf_boot"
=>
-------------------------------------------------------------------------

(7)タイムスタンプ2011/08/28 のflashcfgを使う
　＃2011/03/09版では、-E,-Lオプションが使用できませんでした。

(8)flashcfg -hの表示

obs600-11 nfsrootマウント

U-Bootプロンプトさえ出てくれれば、ブートしなくなっても、uImage.initrd.squeezeのロードと起動であっさり回復は出来そうです。しかし、大きな変更をしたい時や、CFディスクを抜き差しせずに、バージョンの世代変更を確認したい時などは、NFS ルートファイルシステムで起動マウント出来ればそれなりに便利なことがありそうです。以下はnfsrootマウントを試した記録です。

(1) linux-2.6.36 の .config 変更
・make menuconfig の変更箇所 (→部分)

　│    [*] Networking support  --->
　│    --- Networking support
　│          Networking options  --->
→│    [*]   IP: kernel level autoconfiguration
→│    [*]     IP: DHCP support (NEW)          
→│    [*]     IP: BOOTP support (NEW)         
→│    [*]     IP: RARP support (NEW)
　
　│    [*] Network File Systems  --->
　│    --- Network File Systems 
→│    <*>   NFS client support
→│    [*]     Root file system on NFS

→│    <*>   NFS server support                                         
  │    -*-     NFS server support for NFS version 3                     
  │    [*]       NFS server support for the NFSv3 ACL protocol extension
  │    [*]     NFS server support for NFS version 4 (EXPERIMENTAL)      

・.config の差分

このあと、 make uImage; make modules; make modules_install

UIMG=uImage.36_$(date +'%Y%m%d')
mkimage -n "$(date +'%Y%m%d_%H%M')-sda1" -A ppc -O linux -T multi -C gzip ¥

/usr/sbin/flashcfg -f uImage.36_20110620 しました。

obs600-10 BUFFALOアダブタ

前回のPLANEX GW-US300MiniSはパソコンショップで最下段の棚で売れ残りのごとくスミにあったものを偶然見つけて、とてもラッキーに思いました。無線LANチップは何が動くか当たるも八卦当たらぬも八卦で、気が向いたものを買って試しています。現在は、BUFFALO製品が目に入り、そのうちで手に入れた以下を紹介します。

(1) 当方が手に入れたものの動作結果

※1 WLI-UC-G301NはLEDが点灯せず

※2 ソースコードにProduct IDの追加が必要でした。

>       { USB_DEVICE(0x0411, 0x014f) },
さらに、自動でbrctl addif br0 wlanXが追加されない。

※3 インターフェイスは出現するが、SSIDが検索リストに出現しない。
# ifconfig wlan0

          Encryption key:off
          Power Management:on
・MacAddressが変。
wlan0     Link encap:Ethernet  HWaddr 42:76:e6:4c:00:00

(2) 当方の環境での11g電波強度の測定 (単位dBm)

メーカ
型番		同室の
電波強度		2F,1F間の
電波強度
PLANEX
GW-US300MiniS		-54-72
BUFFALO
WLI-UC-GN		-41-58
BUFFALO
WLI-UC-G301N		-40-55
BUFFALO
WLI-UC-GNT		-43-61
La Fonera
FON2100E(参考)		-41-56

当方、木造2階の一軒家では、いずれのUSBアダプタも使用に支障はないようです。
現在11nは未テストです。11n動作は、将来の楽しみとしたいです。当面は主にWLI-UC-GNの11gモードで、ロングラン・エージングテストを行い、安定動作の確認を行おうと思います。

obs600-09 GW-US300MiniSでAP化

無線LAN USBアダプタをアクセスポイントにすることが、可能となっている方がいらっしゃるようなので、同じようにやってみました。

おおもとのネタは、http://wireless.kernel.org/ から頂きました。前回のDebian環境 kernel 2.6.36にて試しました。

(1) make oldconfigでの表示
初めは、linux-2.6.36/ツリーにカブせて、make oldconfig しようとしました。「Support for 802.11n」 にて 11nサポートも始まりつつあるようです。しかし引き続きmakeすると、とてもうまくいきそうにないのでこれは断念します。

無事にhostapdで "handshake completed (WPA)"が出ており、deannaにWifi接続良好です。hostapd起動後6時間くらいスマホ3台接続して様子をみてますが、問題なくWifiネットワーク動作しています。さらに次は、手持ちの無線LANのUSBアダブタで他にも動作するものがあるか試してみたいです。

obs600-08 Debianでmkimage

Debianで運用しだした時、kernelをアップデートするときだけ、ssd-linuxにしてkernelビルドするより、Debianのままでコンパイルするほうが、ドライバの動作テスト等にはスピーディで都合が良いので、ためしにDebianでkernelを2.6.36にしてみたいと思います。

細かい調整をしつつ、次回は、無線LANのAP化に挑戦したいです。

自前でコンパイルしたものでも同様に起動することが確認出来ました。

さらに、kernelバージョン2.6.29 を 2.6.36 にして同じように、ビルドします。

obs600-06 USBメモリBoot

USBメモリにssd-linuxをインストールして、src.tgzのコンパイルビルドをしてみたいと思います。まずは準備編でUSBメモリBootしてみます。
用意したのは「そんな装備でだいじょうぶか」というような低価格なUSBメモリ8GB容量です。２つのUSBスロットのどちらに差しても同じ結果になると思います。今回は下側に挿しました。
もとネタは、ぷらっとホームさんのページセルフ開発環境構築 をこの通りにやってみます。
