test connection成功，但是在工程文件没有看到gel文件

ccs\ccs_base\emulation\gel\c5509.gel， GEL文件是在.ccxml文件中添加的。

Nancy Wang 说：

已经添加了，但问题还是依旧

需要修改cmd文件吗还是修改gel文件

之前有debug成功过吗？请参考以下链接给出的引起 device hung的原因：
software-dl.ti.com/.../ccsv7_debugging_jtag_connectivity_issues.html

这两个文件不需要修改的。从打印信息看memory已经配置过了，应该不是配置的原因，也可以再次通过手动ccs->script再做一次配置，将TCLK调低试一下。

使用codec回声代码可以调试成功，但是当我在代码中加入相关的DMA操作后，出现trouble reading memory block at 0x....的问题

TCLK拉低了，还是出现错误

好的，我试试看，有相关的map与地址内存分配参考的文档吗

我修改了一下cmd文件问题解决了
