Temporal file cache hit score. Each time a file is opened, all

cached files will lose one point. If the opened file is found in

cache, that entry will gain CONFIG_SPIFFS_CACHE_HITSCORE points.
|

One can experiment with this value for the specific access patterns

of the application. However, it must be between 1 (no gain for
|
|
hitting a cached entry often) and 255.

config SPIFFS_NO_BLIND_WRITES
|

bool "No blind writes"
|
|
default n
|
|
---help---
|
|
By default SPIFFS in some cases relies on the property of NOR flash
|
|
that bits cannot be set from 0 to 1 by writing and that controllers
|
|
will ignore such bit changes. This results in fewer reads as SPIFFS
|
|
can in some cases perform blind writes, with all bits set to 1 and
|
|
only those it needs reset set to 0. Most of the chips and
|
|
controllers allow this behavior, so the default is to use this
|
|
technique. If your controller is one of the rare ones that don't,
|
|
turn this option on and SPIFFS will perform a read-modify-write
|
|
instead.

Object name maximum length. Note that this length include the zero

termination character, meaning maximum string of characters.

Note: This config affects the on-flash structure.

config SPIFFS_COPYBUF_STACK

int "Max Stack Allocation"
|

default 64
|
|
---help---

Size of buffer allocated on stack used when copying data. Lower

value generates more read/writes. No meaning having it bigger

than logical page size.

Enable the compatibility with older NuttX versions.

(Older than NuttX 11.0.0, where this option was introduced.)
|
|
|
|
Note: For better compatibility, you may want to disable
|
|
CONFIG_SPIFFS_LEADING_SLASH because those versions of NuttX

didn't have the option.

Assume and ensure that on-flash filenames are always prefixed
|
|
with a slash.
|

This enables the compatibility with images generated by
|
|
the following tools:
|
|
|
|
* mkspiffs

Note: SPIFFS_NAME_MAX doesn't include the leading slash appended

by this option.
