TI中文支持网您好，
我在正常运行的TDA2X(dra7x)平台上（此时已经有图像输出，运行正常），连接XDS110,可以正常launch,xml文件。但是无法连接到A15或者M4，DSP等任何一个core上，反复上电，执行system reset 也不行。请问应该如何操作才能debug？

最近那边在审核邮箱，好像无法发帖，而且海外回复很慢，经常要等1,2日。我这个主要是工具使用问题，如能告知不胜感激。

我在正常运行的TDA2X(dra7x)平台上（此时已经有图像输出，运行正常）
不跑任何程序，直接连可以吗？

user6243290：
可以直接连，但是会停到初始化程序部分，没法继续运行（我使用VSDK0205，好像是必须读srv_cfg配置文件，因此在运行时连接）。我的目的也是在输出图像的位置打断点，观察缓存的数据。故而需要他跳过初始化能够连接。请问该如何操作？

Nancy Wang：
你的情况比较像是已经加载的代码引起jtag无法连接的问题。
In certain scenarios the loaded code may cause issues with the normal connection and/or execution.

由于我对TDA2X不熟悉，可能无法给出相关的建议。看你的是企业邮箱，应该是可以发帖的。
你是已经往板子里烧写了程序才引起的连接报错问题是吗？具体是烧写的什么内容呢？是TI提供的吗？
请详细描述我这边去英文论坛发帖子，再给你贴出来。

感谢回复，我将相关核的.gel删除后连接已经可以了。
