I try to use the lib with an ESP8266 module.

But, the code crash with this line :

((spiffs_page_ix*)((u8_t *)objix_hdr +
sizeof(spiffs_page_object_ix_header)))[data_spix] = data_page;

Fatal exception 9(LoadStoreAlignmentCause).

Thanks for your help

Stéphane

Hi @pellepl,
I'm new here and I'm having the same issue, but I dont know how enable SPIFFS_ALIGNED_OBJECT_INDEX_TABLES.
Can u explain how I do it?

from spiffs.

Look for the file spiffs_config.h - in there are all the build time config defines. Define SPIFFS_ALIGNED_OBJECT_INDEX_TABLES to 1.
