How to use WearLevel in spiffs?

Postby YxWang » Fri Jan 11, 2019 1:15 am

Hi there,

SPIFFS supports wear leveling, but I can't using wl_mount() to mount wear level in SPIFFS partition.
So I have two questions:
1. Is the SPIFFS partition already installed with wearlevel?
2.If 1 is not, how to use Wear Level in spiffs?


regards,
YxWang

SPIFFS does wear levelling internally, and expects that it operates on raw SPI flash. As such, it can not be used on top of another flash translation layer, such as wear_levelling library, or on top of encrypted flash.
