Transfering from an RTOS to Linux

Introduction

 

Many questions emerges when migrating from an RTOS (real-time operating system) to embedded Linux. Furthermore, there are both advantages and disadvantages between an RTOS and OSS (open source software). One of the advantages that developers are moving to Linux is because of its extensive graphics capabilities. On the other side, if you are a sole Linux developer, you might get helps from the community, but not always. Performance and scalability provide reliability when migrating from an RTOS to Linux . Moreover, open source software is free to use. Linux offers many advantages to an organization. For example, to lower licensing costs and improve control over maintainability.

 

RTOS

 

As we know, there are many benefits to moving from an RTOS to OSS. However, there are situations when it is better to stay with RTOS rather than OSS. Here are some factors you might need to think about before moving from an RTOS to Linux. Before making any decision on moving to Linux or not. It’s highly recommended that one to take a look at the end application. To decide whether or not Linux is a good fit. Or maybe an RTOS is a better and appropriate fit.

 

  • Who is going to offer the support you need
  • Cost of development
  • Specific licensing agreement you need to follow
  • How important is it for you to reuse current/existing IP

 

LINUX

 

Real-Time Computing (RTC)

 

How fast is your real-time? Real-time requirement is also a key aspect to be considered when thinking to migrate from an RTOS to Linux. In computer science, RTC describes hardware and software systems subject to a "real-time constraint". On the other side, a real-time system has been described as controls and environment by receiving data and processing and returning the results. Which is sufficiently swiftly to affect the environment at the time.  However, the term “real-time” used in simulation to run at the same speed as a real clock and to avoid significant delay.

 

Security

 

Everyone knows that security is all about risks. Who is going to watch the community for security vulnerabilities? What are the differences in Linux security compares to an RTOS security? An RTOS established by a small group of developers. Therefore, an RTOS security is easier to be managed and maintained than Linux. With Linux, the most important part is to protecting data.  Below is a brief checklist:

 

  • Have a secure boot mechanism
  • Disable all unnecessary communication interfaces and ports
  • Eliminate non-essential services and softwares
  • Check and install software updates regularly
  • Two-factor authentication for accessing the system
