strip the 400 error mesg

表示您的服务器传来的数据长度，比之前查询到的 bin 长度更长。

upgrade crc check failed !

表示 flash 里面写入的 bin 文件 crc 校验不通过。

建议您查证服务器发送的数据是否异常。

感谢您对 ESP8266 的关注！

boot是boot_v1.5.bin, Web Server是 nginx, Url 192.168.5.224:8080/user2.4096.new.6.bin

做OTA結束時會發生1. strip the 400 error mesg 及 2.crc check failed,
然後按ESP8266 Reset並未切換到 UserBin2 開機. 請問如何解決? 謝謝幫忙:)

執行結果如下.,
