ESP32S3 : Little Minimum File Size is 8192 bytes. Why ?
Posted: Thu Jun 05, 2025 1:49 pm
Good afternoon,
I am using Little FS on an Esp32S3 and the FileSystem is located in the internal Flash of the Chip.
Each time I create a new file using Little FS, it seems that the amount of bytes used is 8192 bytes.
However, in the littleFS configuration, the minimum File write size is something like 128 bytes.
Normally, I only write 19 bytes for each line in my file, and the maximum number of line in a file is 80.
So, I would like my file to be maximum 80 * 19 = 1520 bytes and not 8192 bytes.
Do you know how I can change the minimum file size ?
Do you have any idea ?
I don't see anything in the configuration.
Thank you for your help,
Best regards,
Thomas TRUILHE
