Deep Expertise, Practical Solutions

We created YAFFS in 2002 and have been maintaining it ever since. Along the way, we've helped hundreds of companies solve flash storage challenges across every industry imaginable.

Flash storage isn't simple. NAND behaviour, wear characteristics, power-fail scenarios, performance tuning—these are specialised problems that require specialised knowledge.

Our consultants have seen it all: from consumer devices to satellites, from startups to Fortune 500 companies. Whatever challenge you're facing, chances are we've encountered something similar before.

Why work with us?

  • Created and maintained YAFFS since 2002
  • Deep understanding of NAND/NOR flash behaviour
  • Experience across consumer, industrial, aerospace sectors
  • Worked with clients from startups to multinationals
  • Practical, production-focused advice

How We Can Help

🔍

Evaluate your flash storage design before it becomes a problem. We'll review your architecture, identify potential reliability issues, and recommend optimal configurations.

  • Flash device selection guidance
  • File system configuration review
  • Wear levelling and lifetime analysis
  • Power-fail safety assessment
🔧

Integration Support

Getting YAFFS (or another file system) working in your specific environment. We can help with driver development, performance optimisation, and platform-specific issues.

  • YAFFS integration into your platform
  • Custom NAND driver development
  • RTOS and bare-metal integration
  • Performance tuning and optimisation

📋

Code Review

Have your flash-related code reviewed by experts. We'll identify bugs, reliability issues, and performance problems before they reach production.

  • Flash driver code review
  • File system usage patterns
  • Error handling assessment
  • Best practices recommendations
🎯

Custom Development

Need something specific? Custom features, specialised testing tools, or bespoke solutions—we can build what you need.

  • Custom YAFFS modifications
  • Specialised testing frameworks
  • Migration tools and utilities
  • Platform-specific adaptations

Common Problems We Solve

Data Corruption After Power Loss

Devices coming back with corrupted data or failing to boot after unexpected power cuts. We'll diagnose whether it's the file system, driver, or hardware, and fix it.

Premature Flash Wear

Flash devices failing earlier than expected. We analyse write patterns, identify hot spots, and optimise your system for maximum flash lifespan.

Slow Performance

File system operations taking longer than they should. We profile your usage patterns and tune the configuration for your specific workload.

Integration Challenges

Struggling to get YAFFS working with your hardware or RTOS. We've done hundreds of integrations and can get you past the roadblocks quickly.

Choosing the Right File System

Unsure whether YAFFS, JFFS2, UBIFS, or something else is right for your project. We provide objective recommendations based on your requirements.

Field Failures

Devices failing in the field with no clear cause. We help analyse failure data, reproduce issues, and implement fixes.

How It Works

1

Initial Discussion

Tell us about your project and challenges. We'll have a preliminary call to understand your situation and determine how we can help.

2

Proposal

We'll provide a clear proposal outlining scope, approach, timeline, and costs. No surprises, no hidden fees.

3

Engagement

We get to work. Regular communication, clear deliverables, and practical results. We work collaboratively with your team.

Engagement Options

Project-Based

Fixed-scope engagements with clear deliverables. Ideal for specific problems like architecture review, integration work, or troubleshooting a particular issue.

We agree on scope and price upfront. You know exactly what you're getting and what it costs.

Ongoing Support

Retainer arrangements for ongoing access to our expertise. Get priority response times and regular check-ins to keep your project on track.

Ideal for long-term projects or when you want expert guidance throughout development.
