CC3100: cc3100 stm32 mcu通信

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
