[参考译文] TMDSCNCD28P55X：TMDSCNCD28P55X 控制卡上的 LED 闪烁工程问题

工具/软件：

TI 团队大家好、

我目前正在使用 TMDSCNCD28P55X 控制卡进行开发。

我在导入位于以下位置的 LED 闪烁工程时遇到问题：

C:\ti\c2000\C2000Ware_5_05_00_00\device_support\f28p55x\examples\led

Code Composer Studio (CCS) 中。 工程将成功导入、当我逐步调试代码时、它将按预期运行。 但是、当我连续运行代码时、无法跟踪其执行情况。 我随附了一个视频、介绍了调试行为、供您参考。

以下是我所使用的工具版本：

• CCS 版本： 20.2.0.12__1.8.0

• C2000Ware 版本： 5.05.00.00

如果缺少任何问题、或者您对解决此问题有任何建议、请告诉我。
