cc3200 中断的问题

首先，我是刚学习CC3200芯片的，我从淘宝网上买了一块开发板学习。当我在测试CC3200SDK_1.2.0中的example\serial_wifi例子，用EWARM软件通过JTAG方式下载到芯片RAM中运行，main程序中建立了2个任务后执行osi_start()，我一直跟着代码走了下去，当调用portasm.s文件中的vPortStartFirstTask函数里的 “svc 0” （在152行)时，PC计数器不在执行下去了，一直停留在"SVC 0"这一行，这是什么原因呢？

我感觉好像不能进入中断异常，后来又测试了example\interrupt例子,也不能中断。

麻烦哪位工程师帮我解答下，谢谢。

烧了servicepack没有？

您好，我板子的外部SFLASH中有别人做的应用软件的，我并没有擦除掉外部SFLASH中的数据，我直接用IAR软件下载例程中的程序调试的，这样对中断有影响吗？当然后我没有改过例程中的程序。

一开始JTAG连不上芯片，后来看到网上的贴子说需要一个文件“CC31200_JLink.JLinkScript”，我使用了这个文件后才能调试的。

您指的Servicepack是什么？也需要写入外部SFLASH中的吗？

一个版本的SDK对应一个servicepack,请阅读 SDK里的doc,CC3200-Getting_Started_Guide.pdf.

servicepack相当于是补丁。

你好，我已经更新过servicepack，但是好像没用， 程序还是停留在 “SVC  0” 这一行。。。

这是UniFlash显示的内容

1. 先format flash,再烧servicepack， 试一试

2. 换个例子试试先，如getting_started_with_wlan_ap 或者get_weather

我已经格式化flash了，也已经烧写了servicepack,以下是获取的文件列表：

我用IAR打开了getting_started_with_wlan_ap，并重新选择了 J-link作为调试器。成功下载到了RAM，运行时还是停留在了 "SVC 0"

问题解决了，每次下载调试时必须断下电，然后就正常了
