[Resolved]关于OTA升级后 bin文件crc问题

[younger]

Dear Espressif：

我在用贵司1.4版本，自己搭建的OTA Server中，做OTA升级，最后下载bin文件ok，但是：
upgrade file download finished.
flash_crc = 2063597568
img_crc = 314686468

1、请问这两个crc是什么意思？
2、这样的错误可能是什么原因导致的呢？

非常感谢！

您好，

请确认您是否更新到了 esp_iot_sdk_v1.4.0 的 tools 文件夹。

您这个错误很有可能是没有更新 tools 文件夹导致的。请更新 tools 文件夹，重新编译，上传 OTA server，再下载升级，看是否还有问题？

我们在新版 SDK 中加入了 OTA 的 CRC 校验，如果您没有更新 tools 文件夹，就会导致 CRC 校验出错。

谢谢！ 更新后校验正常。

但是有时会出现在擦写flash时，卡住了，然后wdt重启了。

请问这种情况有没有什么办法避免？

[younger]

问题原因找到了。

在擦写的过程中需要关掉相关中断，中断对擦写falsh过程中有非常大的影响。

我用NONOS 2.2.0遇到了一样的问题,并且是在更新了esp_iot_sdk_v1.5.0的 tools文件之后,问题依旧

直接在 PC 浏览器中打开你下载的 URL，看 bin 文件是否会被下载下来。

It says that you need to update to the new ESP8266_RTOS_SDK/tools, this may solve your problem.

最近也遇到这个问题，之前一直把bin文件放到公司服务器上面已经用了几年都升级没问题，前几天对网关升级，发现升级失败显示结果如下：

后面我把文件从外网服务器取下来放到了我本地搭建的服务器上面（自己电脑），测试没问题，搞不懂为什么会这样，我看上面说什么tools更新，这个应该不对吧，毕竟我那个用了两年多了，一直OK.而且我本地服务器验证也OK.下面是我本地服务器的升级的结果相同文件：
