Tuxera EdgeFS

Product overview

Take the guesswork out of storing your data

Most file systems in small, embedded environments are outdated implementations that aren’t designed to protect your data. Tuxera EdgeFS is different. Built from the ground up for 100% data integrity, EdgeFS keeps your data safe even after sudden power loss. Backed by 30+ years of file system experience, EdgeFS delivers unmatched reliability in a compact footprint. It’s fully customizable, putting developers in complete control of your data. Paired with Tuxera FlashFX Tera, it works on top of any NAND or NOR device.

WE ARE TRUSTED BY INDUSTRY LEADERS

KEY FEATURES

Fail-safe by design

Our Dynamic Transaction Point™ technology prevents data corruption during unexpected system crashes and power loss. Your system quickly recovers to a known good state. This keeps your operations running smoothly with your data intact. All of this means faster boot times.

Small footprint

Built for resource-constrained environments, EdgeFS operates efficiently with minimal RAM and storage requirements. Our compact, well-structured file system can be configured to fit your exact needs, using as little as 4 KB of RAM while never compromising reliability.

Direct path to certification

With only 7,036 effective lines of code, EdgeFS makes certification straightforward and cost-effective. We provide all necessary artifacts to support your certification process, from market requirements to code testing.

Tuxera EdgeFS options

Choose the solution that fits your needs.

EdgeFS

EdgeFS is the ideal choice when you need to manage and store mission-critical data without straining CPU and memory usage. It supports larger files and volumes than standard FAT file systems, and works with virtually any storage media, including SD cards, eMMC, NVRAM, hard drives, and NVMe.

EdgeFS CERT

EdgeFS CERT works best for safety-critical applications with the highest reliability requirements. It follows the strict coding standard MISRA C and includes comprehensive documentation. For project certification, a complete set of artifacts is available.

EdgeFS NAND

EdgeFS NAND is designed specifically for SPI NAND flash, with a built-in flash translation layer. It handles everything you need to make NAND flash work properly—from wear leveling to bad block management and error handling. EdgeFS NAND keeps your data safe without any extra batteries or capacitors, saving you storage space and money.

Frequently asked Questions

Have questions about Tuxera EdgeFS?

Here are answers to what customers typically ask about Tuxera EdgeFS. Just reach out if your question isn’t listed here.

Is EdgeFS available in source code?

Yes, EdgeFS is available as fully documented and well-structured source code. This makes it easy to integrate with your systems and to customize according to your exact requirements.

What's the difference between Tuxera EdgeFS and the Edge GPLv2?

EdgeFS includes additional features that aren’t available in the GPL version, along with professional technical support. Our commercial license also gives you more flexibility in how you distribute your products without GPL licensing restrictions.

Is EdgeFS available on my specific RTOS?

EdgeFS is highly portable and works on virtually any RTOS environment. It has been implemented on FreeRTOS, QNX, ThreadX, and many others. Our standard C code can be compiled on multiple tool chains and platforms, making integration straightforward regardless of your environment.

Which SPI NAND parts are supported by EdgeFS NAND?

EdgeFS NAND supports most common SPI NAND flash parts, including single, dual, or quad SPI NAND.

I have limited memory for my project. Would EdgeFS be a good option?

It might be! EdgeFS has a smaller footprint than many options on the market, and it doesn’t hurt to ask. Reach out to us at sales@tuxera.com and get in touch to get the conversation going.

Technical specifications

Detailed product specifications

DATASHEET

Transactional design

Never overwrites live data. Once data is written, it’s always in a determinate state.

Rapid recovery times

Mounts quickly and consistently after unexpected shutdown/power loss.

Maximum portability

Ported to many RTOSs including FreeRTOS, SafeRTOS, μC/OS, ARM mbed, MQX, INTEGRITY, and eMCOS.

Small footprint

Ideal for resource-constrained environments. Configurable to use as little as 4 KB of RAM and 11 KB of ROM.

Supported block device drivers

Works with a broad array of storage media including: HDD, eMMC, SD/MMC, NVRAM, USB mass storage, and SATA (or PATA) disks.

Atomic writes

Metadata never points to wrong user data.

Reliance Edge Configuration Tool

Tuxera EdgeFS offers three options for file system configuration. Each one is thread-safe and completely power fail-safe, protecting your file system structure and user data if power gets interrupted. Flexible transaction point configuration is also available for each option. Key file system operations are deterministic, providing unprecedented predictability.

Flexible configuration options

	Full POSIX	Small POSIX	FSEssentials
	Includes path-based file access, file handles, and atomic directory operations (including rename).	Contains the same POSIX-like APIs Full, but excludes rename.	Supports read, write and truncate on files referred to by a number, which is configured at compile time.
API set	POSIX-like	POSIX-like (not including rename)	Constrained
Number of files	Variable	Variable	Fixed
Number of volumes	Multiple	Multiple	Multiple
Maximum stack depth	824	744	556
Buffers (minimum)	12	6	5
File references	Names	Names	Numbers
Code size (ROM)	17.6 KB	16.7 KB	10.6 KB
