メールボックス用の資源をコンフィギュレータで確保。
- CRE_MBX(MBX_DISPLAY, {TA_NULL, TMAX_MPRI, NULL});

以下の構造体を定義。

 typedef struct {
     T_MSG header;
     unsigned char cmd;
 } display_msg_t;

rcv_mbxで待ちに入る。

     display_msg_t *msg;
     rcv_mbx(MBX_DISPLAY, (T_MSG**)&msg);

現象発生。

仮説1
- ベアメタルアプリケーションで使用していたライブラリを流用したが、それらライブラリが触ってはいけないレジスタを触っているのではないか？

2013-02-17 18:19 Updated by: shintamainjp

댓글 올리기

仮説2
- UZUMEプラットフォームが使用している割り込みを止めた場合、現象が発生しないのではないか？
  - 要するにOSのサービスを使用するにおいて、潜在的に何らかの問題があるのではないか？

仮説3
- 誰もrcv_mbxした事がない。

以下の点はどうでしょうか。

ログ末尾のコール・スタックからどのような関数が呼ばれて最後にどこで問題が発生したか特定できるか。
RETIの値が0になっている。
スプリアス割り込みを引き起こしたタスクは十分なスタックを持っているか。

IPENDとHWERRCAUSEから考えると、"An access was attempted to reserved or uninitialized memory."となって、違法メモリ領域へのアクセスが原因と考えられる。

2013-02-18 06:32 Updated by: suikan

EXCAUSEが0である点が腑に落ちない。しかしIPENDはHWERRだと示唆している。

余剰命令メモリが2kBくらいしかない。ハードウェア・エラーの原因ではないが、注意すべき所。

IPENDレジスタ
- イベントのネスト状態を示すビットマップ。
- 上記例では、0x00008020となっているので、IVHWとIVG15が処理中のイベントという事になる。

RETIレジスタ
- 割り込みから戻るためのアドレスを保持しておくレジスタ。
- RTIが対応する戻り命令。
- 上記例では、0x00000000となっているので、まぁ普通に考えて割り込み戻り番地が設定されていないという事になる。
  - こういう表現が正しいかどうかはわからない。

以下の処理のいずれかを行うと、HW_ERRORが起きなくなる。

INNO_TIMERをSIC_IMASK0でディセーブルする
TIMER2をTIMER_DISABLEレジスタでディセーブルする。

タイマーステータスは何のエラーも示していない。

次のステップでSPORT DMAの停止を行ってみる。
