最近在想用SPI FLASH存参数，跑 wear_levelling 例程 读写出现写入不成功，读出来也不对的现象，不知道具体原因还多指教一下。

[ESP_Gargamel]

spiffs 文件系统烧入了吗？参考 一下 examples/storage/spiffsgen。

[WangXiaohai]

不太一样吧，一个是FAT文件系统，一个是SPIFFS文件系统，我用wear_levelling例程它是用的FAT，我其它几个板子，下进去都可以，就有一个不行

[ESP_Gargamel]

好的，弄错了，是 FAT 的。
那问题变成为什么有一块板子不行，从 log 上看，读写都没有报错。

Code: Select all

I (483) example: File written
I (483) example: Reading file
I (484) example: Read from file: ''
I (484) example: Unmounting FAT filesystem
I (585) example: Done

只是读到的字符串不对了，只有一个 "。

你用命令 esptool.py read_flash 0x200000 0x100000 fatfs.bin 把 bin dump 出来看看，那个字符串有没有写进去。

[WangXiaohai]

好的，谢谢了，我这边试了，估计是 模块硬件上的问题，没有写进去成功，读出来都是0xFF 0xFF，谢谢了
