【问题描述】：
对于一个项目，我尝试使用 ESP8266 RTOS SDK。
第一步我安装工具和工具链。 hello_world 示例和另一个 gpio 示例工作正常。我尝试softAP 示例并得到Guru Meditation Error: Core 0 panic'ed (StoreProhibited). Exception was unhandled 错误。我发现line 62 : .automode = WIFI_AUTH_WPA_WPA2_PSK not 有效。我试过WIFI_AUTH_WEP,WIFI_AUTH_WPA_PSK,WIFI_AUTH_WPA2_PSK，但只有WIFI_AUTH_OPEN才可以使用softAP。有人有相同的行为或一些提示吗？

【问题讨论】：
-
我的建议是分享一个导致崩溃的代码的最小可行示例，然后有人可能会就崩溃的原因提供建议。
-
对不起，我正在编辑代码。
