[参考译文] TMS320F28069M：TMS320F28069上的软件复位不能正常工作(处理器无法重新启动)

问题没有得到解决；问题变得更加严重。 让我更详细地说明一下：

我    使用 MotorWare 18与 LAUNCHXL-F28069M 和 BOOSTXL-DRV8305EVM 配合使用。 未安装 JP1和 JP2。 在调试器下工作时、我使用引导设置：开、开、开。 在此模式下、一切均正常运行、我可以成功调试程序。

调试后、我切换到闪存引导模式。 引导设置为：On (开)、On (开)、Off (关)。 我打开系统电源、程序开始运行、我可以通过闪烁的 LED 进行确认。 但我无法控制电机。 通过 CAN 进行通信时工作正常。

如果我按下"Reset"按钮或执行软件复位、一切都开始正常工作、包括电机控制。 但在首次上电后、电机控制便无法正常工作。

对于可能导致此问题的原因、我希望提供任何建议。   

Andrew。

PS：我有3个  LAUNCHXL-F28069M。 相同。

您能否在进行电机控制的代码部分放置 GPIO 切换开关、您需要查看代码的哪个部分会遇到通过执行 XRSn 来解决的问题。

谢谢

LED 控制位于 MAIN_ISR 中。 主域中的 CAN 通信。

我不确定我的问题是否与 cmd 文件有关。 这是我的命令。

Andrew、您好！

??? ? 说：

LED 控件位于 MAIN_ISR 中。 CAN 通信。

??? ? 说：

可通过闪烁的 LED 进行确认。 但我无法控制电机。 通过 CAN 进行的通信正常。

那么您的电机控制代码在哪里呢？ 是否未执行？

??? ? 说：

但在首次通电后、电机控制立即无法正常工作。

我无法从 CMD 文件中说出任何内容

谢谢
