AP例程异常

Other Parts Discussed in Thread: CC3200

大家好！本人新做PCB+全新CC3200，下载其他程序（非wifi类）都正常，但是下载AP或者STA例程后不断的初始化，故障如下一直显示

*************************************************
CC3200 WLAN AP Application
*************************************************

请问是什么原因，感觉不像是硬件问题，service 和SDK 用过1.2和1.3版本都不行

能详细说明下您的实验流程吗？您可以先看一下 processors.wiki.ti.com/.../CC3200_Getting_Started_with_WLAN_AP

我用的是官方的demo，只是pcb和cc3200新的，谢谢，其他都正常涉及到网络的才异常

没有串口一直重复显示这个信息，我网上看了很多人有这个问题，就是没有人给出解决措施

你去debug不可能没有报错信息。下面这个如果正常会有显示，不正常也会有显示，你看一下卡在哪里了。

    unsigned char ucDHCP;

    // the persistent settings stored in NVMEM (viz. connection profiles &
    // policies, power policy etc)
    //

    // that the device is in its default state at start of applicaton
    //
    // Note that all profiles and persistent settings that were done on the
    // device will be lost
    //
    lRetVal = ConfigureSimpleLinkToDefaultState();
    if(lRetVal < 0)
    {

    }

卡在ConfigureSimpleLinkToDefaultState()里面的lMode = sl_Start(0, 0, 0)

今天测试无意间发现出现此异常时SOP2电平会跟着跳变（平时是高电平，间隔1.2s拉低），测量VCC也会间隔约1.2s有抖动。以上异常是使用的AP demo程序，没有开启NWP时都正常。网上很多人新制作的板有该问题，还请哪位解决了告知下，谢谢！
