Hmm.. I added the '-fm dio' option to use 2 data lines instead but I'm hitting another crash now:

Code: Select allFatal exception (0):

��n't use rtc mem data


The last line says "don't use rtc mem data" but I don't see this string in my code or the SDK. Any other ideas? Or is this just a busted batch of ESP-12Es?

I had this problem when I was using a separate power supply for the ESP-12 and the FTDI module (USB Powered) I was using to communicate with the module. After connecting grounds together the module was stable. Hope this helps.

- Sat Nov 05, 2016 12:40 pm #57705 我也出现同样的问题，我使用了两个方法解决了。
1、更换8266电源。Arduino的3.3V无法给ESP8266蕊片提供稳定的>250mA的供电电流。供电不稳定会造成各种意外发生。如：刷写固件时无法顺利完成，WIFI信号不稳定等！

2、清除ESP8266写入。多次刷入固件后可能造成地址指向错误。

3、刷入新的固件。
