littlefs vs fatfs differences

[gt1]

@robert-hh
yes it was in the same folder. i have a complete folder i transfer over for our project so it is 100% identical to the same files running with the fatfs file system.

this setup has been running over a year whenever we get new wipy in we normally just flash to the newest firmware and it runs fine with putting the files over.

but this time i decided to try the littlefs firmware.

@gt1 How did you verify that the files were actually stored in the file system. Did you run from the REPL something like:

import uos
uos.listdir("")

@robert-hh
I just looked at the files from filezilla. I looked in the folder and the file was there.
i did not do the repl commands but i could try this.

it was strange that it happened on all of the 5 or 6 wipy i tried.

[robert-hh]

@gt1 FileZilla should be fine. Can you open the file from REPL, like:

f = open("config.html")

Dear @gt1,

if you like, you might want to try an unofficial firmware build [1] from our pen where we tried to mitigate some issues with LittleFS the other day.

Let me know if this works for you.

With kind regards,
Andreas.

@robert-hh here is the screen shot of the dir and showing an error opening the config.html file
which i tried opening the index file and it worked.

@gt1 From that screenshot, it looks like the file is called Config.html. Please note the capitalization of the first letter.

@gt1
I just put a wipy that has fatfs firmware with the same folder/ files on it and ran this command f = open("config.html")
and it worked with no errors.

[robert-hh]

@gt1 The file name is "Config.html", you try to open "config.html". Could you try to rename the file to all lowercase letters. FAT is not case sensitive, but littlefs may be. Actually I am not sure.

@robert-hh @andreas Gentlemen thanks. that was it. i didnt notice the capital and since fatfs didnt care i didnt look at it.
