[参考译文] TMS320F28379D：delay_US () 函数非法 ISR 问题

https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1549751/tms320f28379d-issue-with-the-delay_us-function-illegal_isr

工具/软件：

您好：

我的 delay_US () 函数有问题,我有一个程序,每秒和每 2 秒使用 CpuTimer 0.1 和 2 生成中断。 一切都按预期运行。 我已经在主循环中添加了 delay_us 函数、但无论向该函数添加了什么值、一旦启动程序、它就会停止而不会显示错误消息。 CCS 指的是第 164 行的 F2837xD/DefaultISR.c：

中断无效非法 ISR (void)
｛
  //
  //在此处插入 ISR 代码
  //

  //
  //接下来的两行调试仅用于暂停此处的处理器
  //插入 ISR 代码后删除
  //
  ASM（“   ESTOP0“）；  （第 164 行）
  for（；；）；
}

我尝试在 F2837xD/examples 中将时钟频率设置为 200MHz、但没有发生任何事情、问题是恒定的。

有任何线索吗？ 如果您有任何疑问、请随时与我联系。

提前感谢您、

Florentin
