TI中文支持网大家好
我最近在研究CC3200 OTA升级问题，我按照APPENDIX的过程做了，同时，修改了COMMON.h文件的路由器设置
然后我又在DROPBOX里面建立了文档，生成了“f80_sys_mcuimgA.bin”文件。
可是我不知道在附录提到的/sys/mcuimg1.bin 中的URL的“1st OTA Image” 是什么意思？这个IMAGE文件是在哪里可以找到呢？
然后我用TERA TERM出来的图片总是显示UPDATE ERROR RETRYING
请问下改如何解决这个问题？
谢谢了
Yameng Sun：
/sys/mcuimg1.bin 应该就是example/ota_update 工程生成的.bin文件吧？
请问一下你是怎么在dropbox里建立文档的？我按照说明做，DropBox网站都登不上怎么办

Yameng,
您好！
TI 目前OTA只有基于dropbox的demo，需要通过VPN登录。 如果不行的话，建议直接上自己的服务器，把dropbox那一段替换成自己的协议。谢谢！

Edits_for_OTA.zip 这个下载链接还有？在OTA NOTE.pdf里面提及的。
