TI工程师好，想请教以下问题：

我通过STM32 mcu 通过spi与cc3100通信，目前通过串口已经烧写完成servicepack_1.0.1.15-2.14.0.0.bin

我移植了例程到mcu程序，通过spi测试例程成功，然后使用getting_started_with_wlan_ap/station例程卡在_SlDrvSyncObjWaitTimeout里。

正常调用sl_Start函数得用多长时间呢？mode = sl_Start(0, 0, 0); 有时候会耗时1分钟多返回mode = 3

接着继续执行 retVal = sl_WlanSetMode(ROLE_STA); 最后进入LOOP_FOREVER()

想请问怎么排查问题

您好，

sl_Start是用来打开NWP的，若没有回调函数它应该是阻塞的；若有InitCallBack，它将立即返回。

Sl_Start – This function initializes the communication interface, sets the enable pin of the device, and calls
to the init complete callback. If no callback function is provided, the function is blocking until the device
finishes the initialization process.

_i16 sl_Start(const void* pIfHdl, _i8* pDevName, const P_INIT_CALLBACK pInitCallBack);

所以您可以重点检查一下你是否在 sl_start 提供了回调函数。
