你好:
这个可以在给出异常的地址在相应生成的.S文件中查找异常的原因。如果使用的是user1.1024.new.bin,那么就在user1.1024.new.S文件里查证exception地址“0x40221908”,然后在代码添加打印进行调试。如果使用eagle.irom0tex.bin,就在eagle.S中查找exception地址。有关异常重启等原因请关注esp8266_reset_causes_and_common_fatal_exception_causes_cn文档。连接http://espressif.com/zh-hans/support/download/documents
