esp_littlefs: mount failed

[NhanDoremon]

I am trying to follow this tutorial to show Jped Image wih JPEGDecoder: https://www.youtube.com/watch?v=4eD6recBq4M I get the following error:

clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO, clock div:1 load:0x3fff0030,len:1184 load:0x40078000,len:13260 load:0x40080400,len:3028 entry 0x400805e4 File Test!

E (941) esp_littlefs: ./components/esp_littlefs/src/littlefs/lfs.c:1225:error: Corrupted dir pair at {0x0, 0x1} E (941) esp_littlefs: mount failed, (-84) E (944) esp_littlefs: Failed to initialize LittleFS

Can someone please tell me what I need to do to fix this?

Thank you for all to see, I have sovled this problem. I think my ESP32 and another things maybe have conflict with LittleFS. So my solution is that: Replacing all the keyword of "LittleFS" to "SPIFFS in the main code. Example: fs::File jpgFile = LittleFS.open( filename, "r"); ----> fs::File jpgFile = SPIFFS.open( filename, "r"); Moverover, I aslo changed all the command like above in JPEGDecoder.cpp and hide the command #include LittleFS.h. So, that all my solution, after alterning it work well, but the speed to read and decoder Jpeg image is few slow. If you have any other solution. Please give a comment below for everyone.

[Bodmer]

SPIFFS is being deprecated. I suggest that LittleFS is used.

[RDJunc]

Bodmer, your libraries have been invaluable to a great many people, thanks very much.

I also ran across this problem and understand that LittleFS is the preferred file system. All good but how to make that conversion is not very easy to find. Might I suggest that you provide a description?

I changed all the SPIFFS reference to LittleFS but that still did not work. I went into the JPEGDecoder.h file and commented out the #define SPIFFS LittleFS line. I have my test code working but I am not sure this is the right way to resolve this issue. Is this all that is needed?
