2007-06-27 舊平成拾玖年皐月拾參日 (水・晴) [長年日記]

筋肉痛。

左足が腫れて痛かつたので、きのふ一日變な歩き方をしてゐたら筋肉痛で動け無かつた。

KURO-BOX/PRO (No.20) miconapl に附いて見てみた。(參)

きのふ miconapl の使はれ方を診てゐたが、何もコマンドライン・オプションを指定してゐ無い時にどうなるかは見てゐ無かつたので、何も附けずに實行してみた。

# ./miconapl
Usage: miconapl ver.1.11(Dec  4 2006) OPTION
 for OPTION
  -d{0,1,2,3} : set debug level
                bit0:function trace
                bit1:pakcet trace
  -i FILE : communication device(/dev/ttyS0)
  -l      : for local debug
  -p      : micon watch daemon
  -f      : no fork for micon watch daemon

デバッグ・モードが在つたので其れを附けて温度を取得してみた。

# miconapl -d 3 -a temp_get
>SetDeviceName
>Initialize:/dev/ttyS1
>AdvisoryLock (1)
>argCmd: argc=1 argv[0]=temp_get argv[1]=(null)
>argCmd: opecode:0x37, opesize:1, write:0, read:1

------- (SendCmd) len=3 -------
000: 80( ) 37(7) 49(I)
header:0x80 0x37: cmd=01 len=00 ope=37
--
>Output (len=3)
------- (Output) len=3 -------
000: 80( ) 37(7) 49(I)

000: 81( ) 37(7) 23(#) 25(%)
>Input:len=4
------- (RecvPacket) len=4 -------
000: 81( ) 37(7) 23(#) 25(%)
header:0x81 0x37: cmd=01 len=01 ope=37
--
>RecvPacket:len=4
>AnalyzeRecvPacket:Compare Command 0x

結果を診ると、

マイコンとの遣り取りには /dev/ttyS1 が使用されてゐる。
最初にマイコンに對して「80 37 49」を送信。
其れからマイコンから「81 37 23 25」を受信。

してゐる模樣。最初にマイコンに對して送信した 3 bytes の 16 進數は「KUROBOX/PRO マイコン通信仕樣 Rev.1.0」を診ると、

0x80 -- マイコンからのデータ讀出し指示(bit7 が「1」)でデータは無し(データ・ペイロードの長さが「0」)。
0x37 -- 温度を取得するコマンド。
0x49 -- パリティ(0x00 - (0x80 + 0x37) = 0x00 - 0xB7 = 0x49)。

と成つてゐて大體説明書の通り。受信データの方も、

0x81 -- マイコンからのデータ讀出し指示(bit7 が「1」)に對する應答で、1 byte のデータが在る(データ・ペイロードの長さが「1」)。
0x37 -- 送信されたコマンド(温度取得コマンド 0x37)。
0x23 -- 返信された温度(0x23 は 10 進數で「35」。即ち現在の温度は攝氏三拾五度。)。
0x25 -- パリティ(0x00 - (0x81 + 0x37 + 0x23) = 0x00 - 0xDA = 0x25)。

と成つてゐて大體説明書の通り。

だとすると「KUROBOX/PRO マイコン通信仕樣 Rev.1.0」で解説されゐるコマンドを /dev/ttyS1 に書込んで、戻つて來たデータを解析すれば、自分でも温度の取得、空冷扇の制御等が出來るかも知れ無い。

KURO-BOX/PRO (No.21) ファームウェアの初期化を試した。

色々弄つた後でファームウェアの初期化を行つて失敗すると衝撃が大きいので、今の内に一囘試して置いた。

作業に當たつて以下のものを用意した。

母艦と KURO-BOX/PRO とをクロスケーブルで結び、TFTP サーバは WinXP 上で動かした。

一方、SCON-KIT/PRO を使つてシリアル - USB でも結び、此方は VMware Server の上で動かしてゐる Gentoo で minicom を使つて操作した。

「シリアルコンソールを使用したファームウェア書き換へ手順」(PDF)に随つて母艦のネットワークの設定を行ひ、TFTP サーバのデータフォルダにファームウェア書換キットに含まれてゐる、

uImage.buffalo
initrd.buffalo

を置いて KURO-BOX/PRO を再起動した。

Hit any key to stop autoboot:

と出力された處で適當なキーを打ち込むと、ERROR 燈が點滅し「ぴーぽー」と云ふ警告音が鳴り響いたが其之儘無視して大丈夫だつた(最初は驚いて reset して了つた)。

以下に全ての出力を載せた。
