Dear TI support,

         如上的ccs uniflash log，在Service Pack Updata出现了“Open operation failed”，硬件应该没有问题，因为flash的擦写是没有问题，能帮助分析大概是什么原因么？使用的flash为：winbond 25Q16CV1G

有没有尝试过先format一下SFLAH，然后在进行相关的program操作？

谢谢

Ken，在Service Pack Updata之前我是有做Format，且没有报错。就是无法执行Service Pack Updata和Program。后来我发现不能Program的serial flash尾缀不同，能成功Program的丝印为：winbond 25Q16CV1G 1234，不能成功Program的丝印为：winbond 25Q16CV1G 1240，但是既然可以Format和擦除，证明CC3200和serial flash是可以通讯的，且serial flash工作是正常的，是否CC3200底层兼容性不够好。

我也遇到了同样的问题。而且很奇怪的是开始是没有问题的，后来就一直不行了。

丝印的后缀只是批号，不应该是这个问题吧？您如果找到了真正的原因能否分享一下。谢谢了！

论坛有类似问题，解答请看这边： https://www.deyisupport.com/question_answer/wireless_connectivity/wifi/f/105/t/69350.aspx

谢谢回复！

但是没有解决我的问题。

我完全是按照那个帖子的操作方法和步骤在烧写service pack 和程序，开始正常，后来某次之后就总是出 open operation failed 错误了。

刚刚换了 flash，好了。怀疑是 flash 被烧坏了。但是为何会坏，还是一头雾水

Hi Calvin，

您好！
您是使用的EVM还是您自己设计的板子？自己的板子的话用的是我们推荐的Flash型号么？Flash坏的几率很小那？谢谢！
