SDK：ESP8266_NONOS_SDK_V2.0.0_16_07_19和ESP8266_NONOS_SDK_V2.0.0_16_08_10，两个SDK都会重启，log信息也相似，epc1位置也一样
BOOT文件：boot_v1.6.bin
FLASH SIZE：8Mbit
每次升级都会出现该错误，但是我将运行的userbin和地址打印出来看，下载成功，也在跑新的userbin了，就是每次升级完reboot都会出现Fatal exception错误重启。
Fatal exception (28):epc1=0x4000df2f
user1.1024.new.2.S文件里找不到该对应地址。
是否是ROM里面代码问题？
- 4000e190 <memset>
- 4000df48 <memcpy>
- 4000dea8 <memcmp>
- 4000de84 <bzero>
- 4000e1e0 <strstr>
部分关键打印log如下：

img_crc = 501400701
