Why Use Linux in Embedded Solutions Development

There was a continuous demand for a powerful and flexible operating system in the world of server computing. So, here Linux stepped in.

Its open-source nature, resilience, and extensive community support make this operating system a popular choice among software development companies. Recognizing its potential, software manufacturers utilize Linux in embedded solutions development. The flexibility of this OS allows the developers to adapt it to various devices and industries, which makes Linux so widely used. 

Here are just a few common use cases:

• It is used to power devices we don't imagine our lives without. Smartphones, tablets, smart TVs, wearable fitness devices, and smart home devices owe to embedded Linux for seamless operation.
• In the automotive industry, embedded Linux system allows to power infotainment systems, drive navigation systems, enable Advanced Driver-Assistance Systems (ADAS), and power vehicle diagnostic tools, among many other benefits.

Apart from that, embedded Linux solutions are found in healthcare IoT, industrial automation, aerospace, defense, energy management systems, and many other fields where reliable computing systems are required.

Common Challenges in Adopting Embedded Linux

Despite being highly flexible, the adoption of embedded Linux solutions comes with its own set of challenges. Embedded systems have specific features, making them different from regular computers. Thus, it can be challenging to make Linux work well on them. These challenges include:

Limited Resources

Resources like storage, processing power, and memory are often limited on embedded systems. For this reason, it can be challenging to deliver the desired functionality.

Incompatible Hardware

Embedded systems are known to have specialized hardware components, which makes the adoption of the Linux OS challenging. It often requires either kernel modification or custom device drivers.

Stability

As Linux is constantly developing, there is a risk of hardware incompatibility and  potential instability in device performance. That’s why only developers with relevant experience must work on embedded software systems to make them reliable.

Safety and Security

Most devices that run on embedded Linux have a connectivity feature integrated by default. This makes them vulnerable to security threats and prone to hacking attacks.

Increased Development Cost

The adoption of embedded Linux solutions might be pricey as it involves specialized hardware and additional resources. They usually include: 

• more powerful processors;
• additional licensing;
• bigger memory capacity;
• integration challenges;
• maintenance and support services. 

All this contributes to the higher development and production costs.

Limited Battery Capacity

Most of the time, devices with embedded software solutions are powered by the battery. Thus, manufacturers strive to balance the device's performance and power efficiency. Usually, it involves optimizing the kernel, system components, and drivers to minimize energy usage.

Customization

Despite being flexible, the Linux OS can take time and effort to implement the specific requirements of the embedded solution. Providing updates to the delivered system can be challenging as well.

Ways to Overcome Embedded Linux Development Challenges

The challenge is just a mountain waiting to be climbed. With the right approach and proper planning, the adoption of embedded Linux technology is another technical moment. Let's explore life hacks to make the development process smooth and enjoyable.

Collaborate with a Hardware Provider

It's recommended to get involved in the hardware creation process from the beginning. Ensure compatibility through prototyping and testing. At this stage, you can foresee potential issues and step in to avoid their negative impact.

Mind Resources

When developing embedded Linux solutions, use lightweight libraries and optimize code for efficiency. It's also recommended to optimize the core by reducing unnecessary services or modules and practicing hardware acceleration.

Manage Power

Reduce power consumption by applying power-saving techniques such as dynamic frequency scaling and idle-state management. It's also worth using power profiling tools to identify and optimize power-hungry components. 

Keep up to Date with Security

Follow the secure coding practices first thing to decrease hacking risks. It's recommended to keep up with safety vulnerabilities and use frameworks and libraries that provide built-in security features.

Use Ready-to-go Solutions

Use libraries and frameworks tailored to embedded systems needs. This can significantly minimize the development effort, thus reducing the development costs. Using a ready-to-go solution is always faster than developing features from scratch.

Conclusion

Embedded Linux system lies in the heart of many devices we use in everyday life. These devices include smart TV's, industrial machinery, medical equipment, and automotive systems.

Of course, along with the inspiring taste of unlocking the potential of embedded Linux comes a fair share of challenges faced when adopting it.

Software development companies often deal with:

• limited resources;
• incompatible hardware;
• safety and security;
• stability
• increased development costs;
• limited battery capacity
• customization difficulties.

There's nothing impossible in the world of technology, and even the biggest challenge can be resolved with the right approach. Embedded Linux software adopters usually collaborate closely with the hardware providers, optimize power management, prioritize security, and use ready-to-go solutions. All this helps them to create a robust system, using the technology's potential to the fullest.
