TMS320F28030:TMS320F28030

Part Number: TMS320F28030

MCU型式：TMS320F28030ソフトウェアが正常に機能していない状況が発生しています。（ROMの値が0でもなく、1でも中間状態のような異常状態になっていると推定していますが明確ではない）

レジスタ：XDS100v2 USB キャプチャを使用して、マイコン内部の ROM の値や RAM の値をモニタすることを検討しています。

「Loading option」にはプログラムをしない「Load symbol only」を選択してアクセスを試みようと考えていますが、このアクセス方法でROMの状態が異常状態から状態が変化してしまわないか？について調査したいと考えています。過去に経験があればご教授ください。お願い致します。

    MCU model: TMS320F28030 I am experiencing a situation where the software isn't functioning normally. (It is presumed that even if the ROM value is neither 0 nor 1, it is in an abnormal state like an intermediate state, but it is not clear)

    Registers: I'm considering using the XDS100v2 USB capture to monitor internal ROM and RAM values.

    I'm thinking of trying to access it by selecting "Load symbol only" that does not program the "Loading option", but will this access method change the ROM state from an abnormal state? If you have experience in the past, please let me know.

    When you connect the target, it loads GEL file, which resets the target. You can either modify the target configuration file, not to load the GEL file or you can modify the GEL file, and comment the Reset() function which is called inside OnTargetConnect() function.

    . 

    Then connect the target. Once the target is connected, you can load the symbols.
