28377d芯片下载程序出错的问题

Other Parts Discussed in Thread: UNIFLASH

做的板子上有两路28377d芯片，电路完全一样，但是其中一路下载程序正常，另一路出错。具体错误如下，求各位大佬帮我，万分感谢！

C28xx_CPU1: GEL Output:

    那您现在使用UNIFlash能识别芯片吗？用的是同一个仿真器？

    您好，谢谢回复。我这次没有直接debug，而是一步步地连接、下载。发现连接也连接不上，报错如下：
    C28xx_CPU1: GEL Output:

    另外，我是新手，请问UniFlash是什么，怎么用呢？

    CCS Uniflash is a standalone tool used to program on-chip flash memory on TI MCUs and on-board flash memory for Sitara processors. Uniflash has a GUI, command line, and scripting interface. CCS Uniflash is available free of charge.

    Uniflash 可以独立下载固件到芯片，您可以下载来看一下

    您现在提示的这种错误，之前也有客户遇到过，大部分都是硬件或者仿真器连接上的问题

    您好，我下载了Uniflash试了试，结果还是报错，如下：

    我做了两块板，另一块板上的这路芯片可以下载程序，电路是完全一样的。

    那请请测试一下复位引脚的电平。另外这两个芯片烧录时的配置都是相同的？
