Flucard firmware ver3.65でtelentdを有効にする方法


まず、とんすけぶろぐ: FlucardでプログラムとかCGIとかにて配布されているdelpoy~.zipの最新版を持ってきます。

readme.txtにあるとおりにコピーしてもいいのですが、これだけではtelnetdが有効になりません。

私の環境では、コピーした後、autorun.shだけを以下の内容に差し替えて使っています。

#!/bin/sh

is_prevent_auto_start_wifi=no

mount -t devpts /dev/pts
/mnt/sd/DCIM/122_TREK/busybox telnetd -l /bin/sh &

/mnt/sd/DCIM/122_TREK/busybox tcpsvd 0.0.0.0 21 ftpd -w /&
sleep 1
/mnt/sd/DCIM/122_TREK/sbin/dropbear -A -N root -C admin -U 0 -G 0
sleep 1

「is_prevent_auto_start_wifi=no」というのはver3.65では、autorun.shが存在していると、wifiの自動起動を無効化しているように見えたため、入れてみました。
手動でwifiをonしてる場合は関係ないはずです。

ただ、いまのところ、この設定を入れてみても、wifiの自動起動をしてくれない感じです。
(exportをつけてみても同じ)

Flucard firmware 3.24と3.65のファイル上での違い


バイナリファイルは結構違うようだけど、とりあえず、それは置いておく
それ以外の違いについて調べた

/etc/init.d/rcS における差

・読み込むモジュールが変わった

冒頭で「ka2000-sdhc.ko」を読み込む(以前はコメントアウトされていた)

-#insmod /lib/ka2000-sdhc.ko
+insmod /lib/ka2000-sdhc.ko

中盤で読み込んでいた「gpio_i2c.ko」を読み込まなくなった。

-insmod /lib/gpio_i2c.ko
-#sleep 1
+#insmod /lib/gpio_i2c.ko

・自動wifi起動関連の処理が入った

+is_prevent_auto_start_wifi=no
+
+get_config -p "Auto Start Wifi"
+original_auto_wifi_value=`cat /param_value.txt`

など

・/mnt/sd/autorun.shというファイルがあるときは自動wifi起動が実行されない
という設定を入れられている。

 # autorun.sh from sd in case need to perform some test mode
 if [ -f /mnt/sd/autorun.sh ]
 then
        sleep 1
+       is_prevent_auto_start_wifi=yes
        chmod 777 /mnt/sd/autorun.sh
        /mnt/sd/autorun.sh

 fi

・自動wifi起動関連処理の続き

+if [ "$is_prevent_auto_start_wifi" = "no" ]; then
+       get_config -p "Auto Start Wifi"
+       autowifi=`cat /param_value.txt`
+       if [ "$autowifi" = "uap" ]; then
+               if [ ! -f /wifi_flag.txt ]; then
+                       uap
+
+                       # check and disable wifi after timeout if no station connects
+                       check_sta.sh &
+               fi
+       fi
+       if [ "$autowifi" = "sta" ]; then
+               if [ ! -f /wifi_flag.txt ]; then
+                       w2
+               fi
+       fi
+fi
+# set the default value if it is not set
+if [ "$original_auto_wifi_value" = "" ]; then
+       set_config -p "Auto Start Wifi" -v  "uap"
+
+fi

/etc/mtab における違い
・「none /dev/pts devpts mode=0622 0 0」が削除された
telnetdを消したことによる変更。

/etc/uaputl.conf における違い
・MaxStaNumの値が5から8に増加
同時接続数が増えた(「Max number of stations allowed to connect」)

/etc/uaputl_sender.conf というファイルが追加
「Trek_FLUCARD_WiFi」に関する設定が入っている。
かなり細かい設定が書かれている。

FLUCARD GEN 2とGEN 3の違い


firmwareアップデータのデータを確認すると、「FLUCARD GEN2」と「FLUCARD GEN3」というものが存在しているらしい。
「FLUCARD GEN1」は、黒いFLUCARDのことだと思われる。
「FLUCARD GEN3」が何をさすのかがよく分からない。16GBモデルのことなんだろうか?

それは、ひとまずおいておくとして、firmwareを見る限りでのFLUCARD GEN 2とFLUCARD GEN 3の違いを確認してみた。
busyboxバイナリ自体は同一の様に見える。
設定ファイルやWeb管理画面のテンプレートレベルでの差異は、以下の様になっていた。
GEN 3では、いろいろと音が鳴らないような感じになるのか?

Flucardのbuzzerコマンド


flucardは、まずスロットに入れた際、低い音で1回鳴り、おそらくOSが起動したタイミングで、ちょっと高い音で1回鳴ります。

また、autorun.shで実行時にbuzzerコマンドを呼び出し、音を鳴らしています。
autorun.shでは「buzzer -t 1」とか「buzzer -t 5」とかあるので、「-t」はtimeオプションで値は秒かな?と思っていました。

しかし、いろいろ実行してみた結果、以下のような感じでした。

-t 1 : てぃーらーろーれー(音が下がっていく
-t 2 : ちょっと高い音
-t 3 : てぃーれーろーらー(音が上がっていく
-t 4 : てぃーらーろーれー(-t 1よりちょっと高い音で、音が下がっていく
-t 5 : ブザーを止める
-t 6 : ぴー、ぴー(1個、音があがる)
-t 7 : ぴー、ぴー、ぴー(と短音リピート + コンソールに「WAITING_indicating」という出力
-t 8 : ぴー、ぴー、ぴー(と短音リピート
-t 9 : コンソールに「SHAKE_DETECT」という出力
-t 10以降は無い模様

「-t 5」で止めない限り、Flucardをスロットから外すまで鳴り続ける感じです。

使い方としては・・・

buzzer -t 3
sleep 2
buzzer -t 5

という感じで記述すると、音が上がっていく感じのブザーが2秒間鳴る、というところです。
