ESP32-S3-DevKitC-1 v1.1开发板的nvs分区可以写入，但是无法正常读取出来是怎么回事？

ESP32-S3-DevKitC-1 v1.1   开发板。



这个开发板大概是半年前我买的，一直在用。最近调试的时候一直发现，程序运行不正常，上一个蓝牙信息掉电的问题也是我发布的。今天终于找打原因了。



这个板子的nvs分区可以正常写入，但是读取出来的时候数据读不出来。下面的日志是我测试的nvs_rw_value这个例程的日志。发现数据读取不出来。这个日志是官方例程直接编译烧写的，一点修改都没有。



今天下午我在测试adf 的tone分区音乐播放时也出现了，tone数据写入flash成功了，用esp_tool.py 脚本吧flash读取出来，发现也确实写入了。但是在程序里面读取的时候返回的值就是0xFF。但是相同的程序写入其他开发板就好使。所以怀疑是这个开发板的问题。



但是这个开发板的nvs分区 tone分区我都修改位置都一样读取出来不正确。但是很奇怪的是编译好的程序都能正常运行。



麻烦官方的看一下吧，是哪里有缺陷还是什么问题。应该不是flash的问题，因为吧程序分区换个位置也都能正产运行。
