Is SPIFFS limited in size?

[fly135]

I have a 2MB sppiffs partition and once I get to about 1.5MB I get errno 28 (not enough space) after a write. I increased the partition to 3MB with no luck. I can write to a different partition. And I'm able to write up to about 1.5MB on this one. Don't see a size limit in the docs.

I've used 14 MB SPIFFS (on WROVER with 16MB Flash) without issues.

Well darn, that leaves me with a mystery. All I did was change the file name to point to my other partition and it wrote fine. On the failing partition it writes 128 bytes (out of 80044) and fails to write with errno set to 28. But have 400K free.

Hi,

Which ESP32 IDF version are you using? And are you using SPIFFS component provided into IDF or any customer third party component like loboris provided?

Because we have used more than 2 to 8 MB for SPIFFS partition into our project in which we are able to read and write files without any issue.

Please share details regarding issue with code snippet to help you quickly
