 # SPIFlashFileSystem
 
-The SPIFlashFileSystem (SFFS) library implements a basic [wear leveling](https://en.wikipedia.org/wiki/Wear_leveling) file system intended for use with SPI Flash devices, using either the built-in [hardware.spiflash](https://electricimp.com/docs/api/hardware/spiflash) object on imp003 and above, or an external SPI Flash plus the [SPIFlash library](https://github.com/electricimp/spiflash) on the imp001 and imp002.

 ### Hardware
 
-The provided tests require an [imp003 Breakout Board](https://electricimp.com/docs/hardware/resources/reference-designs/imp003breakout/) or [imp003 Evaluation Board](https://electricimp.com/docs/hardware/imp003evb/). Any other boards with imp003 and above containing SPI flash with available user space may work too.

 ## To Do
 
-- Add *start* and *end* parameters to *seek()* as per the [Squirrel Blob obect](https://electricimp.com/docs/squirrel/blob/seek/)
+- Add *start* and *end* parameters to *seek()* as per the [Squirrel Blob obect](https://developer.electricimp.com/squirrel/blob/seek/)
 - Add an append mode (`"a"`) to *open()*
 - Add an optional asynchronous version of *_scan()* which throws a ‘ready’ event when fully loaded
 - Add an optional *SFFS_PAGE_SIZE* (4KB or multiples of 4KB) to reduce overhead
