麻烦下载并解压缩附件，将 AT_target.bin 烧录到 0x00000 地址，无需再烧录其他文件。

重新上电运行后，波特率 115200，输入 “AT”，回车，看是否有回复？

如果您的问题仍未解决，麻烦提供烧录时的 ESP Flash Download Tool 截图和 上电运行时的 log 以供分析。

但是在最开始我没有写错代码误操作wifi_softap_set_config这个函数的时候，都不会有问题。我是误操作了这个函数之后，导致溢出。才遇上反复重启的问题。望可以解决。

您的问题是：您的模块运行一段时间后，就会自动反复重启，必须重新烧录固件 才能正常运行，运行一段时间后，又再次反复重启吗？

能否详细描述一下问题的复现步骤，如果是使用 AT 固件，请问重启之前，执行了哪些 AT 指令，返回值是什么？

麻烦使用 ESP Flash Download Tool 烧录固件，如果您的问题未能解决，请提供烧录过程中 ESP Flash Download Tool 的截图以供分析。

我的flash_id是4014，这个应该是一个1M大小的flash。blank.bin分别刷到0x7e000跟0xfe000俩个地方。刷at固件或是nodemuc，或是自己写的固件都能使用，但是过一会就开始反复重启。

我曾经试试过调用system_restore()和system_restart()这两个函数，也无效。

我还尝试dd出一个1m大小的空文件，把flash都刷成0x00，然后再刷blank和固件，也都不能解决重启的问题。

望能给出解决方法。

您可以重新烧录 blank.bin 或者调用 system_restore 和 system_restart 复位 ESP8266。

感谢您对 ESP8266 的关注！
