C2000-GANG Programmer 8路输出不稳定

Other Parts Discussed in Thread: C2000-GANG, TMS320F28027

问题描述：C2000-GANG Programmer 有8路输出，经实际测试发现，只有6路能稳定下载到MCU中

当随机5路一起工作的时候，4，5输出口有时会下载报错，其他口偶尔下载报错；

当随机6路一起工作的时候，4，5输出口有时会下载报错，其他口偶尔下载报错；

当随机7路一起工作的时候，4，5输出口经常会下载报错，其他口无下载报错；

当8路一起工作的时候，4，5输出口一直下载报错，其他口无下载报错；

去除4，5输出口，其余6口能稳定输出下载。

PS：期间为芯片单独外部供3.3V电和用编程器供电两种供电方式均已试验，结果如上;

所用芯片为TMS320F28027

问题：上述问题是什么原因导致的，怎样能让8路均能稳定输出下载？

    请问下载报错的具体信息是怎样的呢？每次都是相同的报错信息吗？

    能否请您给出相关的截图？

    另外您是否对C2000-GANG Programmer进行Self Test？能否给出相关报告？

    很抱歉没有说清楚

    www.ti.com.cn/.../spruhs0c.pdf

    的 2.4 Self Test

    这个是主要对编程器进行自测，已排除其本身出现问题

    Tools→Self Test 会有一份报告出来，请您上传一下

    Self Test 测试是没有问题的。

    您是否可以单独测试第4路和第5路？请您实验后上传下错误信息，谢谢
