Advantages: Porting Android/Embedded Linux for Fleet Management, Telematics, Infotainment Applications
Porting of open-source Linux and Android instead of porting a proprietary operating system for Connected Car, Telematics, Head-Up Display applications, offer several advantages.
Following are some of the advantages:
- Apache v2.0 licensed. This means these are open-source software and hence, one ends up saving licensing costs.
- Support and maintenance services for proprietary OS, device drivers and kernels may not be available free of cost.
- Porting Android or Linux operating systems provides flexibility to the project. Your developers can integrate customized and open-source software packages and components.
- Linux or Android porting, more often than not, results in reduced time-to-market. This is due to the availability of open-source software packages that may need minimum customizations.
Before kick-starting your Android or Linux porting projects, these are some of the best practices your embedded software development partner should take care of:
Selecting a Robust Hardware Platform
While selecting a SoC or SoM/SBC, one should consider:
- Business Requirements of the application
- Power consumption specifications
- BoM cost, Life-time of Chipset and support
- Memory and Speed capabilities of the processor
Bootloader, Device Drivers & Kernel
- Design a two-stage bootloader – primary and secondary bootloader
- Bootloader design should have low memory footprint
- Develop robust, bug-free and maintainable drivers as per Linux/Android coding standards
- Plan and implement efficient faults-handling, reporting and recovery from errors
- Device drivers should not contain any dead code or unused variable
- Optimise usage of memory space after code compilation

FAQs on Android/Linux Porting Services
Ans. One-stage Bootloader, inherently by design becomes a very large single software package. It requires more memory space (this increases cost) and becomes difficult to manage and maintain. Thus, a multi-stage bootloader appears as a practical choice for dynamic embedded applications that involve managing multiple functionalities and operations.
Having two-stage Bootloader software offers you the following benefits:
- Managing System Start-up Applications: Some necessary start-up programs (that can’t be delayed until the entire OS is loaded) like display of OEM brand logo or branding animation, switching on the camera vision and more can be best managed using two-stage Bootloader software.
- Re-programming or Flashing of target devices: A two-stage Bootloader design facilitates more efficient flashing of field-deployed IoT devices. Your in-house or technology partner’s support team just needs to make necessary configurations in the 1-stage. Based on the instructions, Bootloader will then execute the new firmware image.
- Cost Optimization: Generally the 2nd stage of the Bootloader is designed using low cost memories like EPROM, EMMC, NOR flash memory, or SD cards. These memory types can also be reprogrammed more easily. This offers the flexibility to add more functions or features to your applications in the future, at lower costs.
- Error Recovery: In case of an error or exception, a multi-stage bootloader supports easy recovery of the system, as compared to a single stage bootloader. In multi-stage bootloader, the primary bootloader is booted into internal ROM & RAM. Meanwhile, a two-stage Bootloader can be loaded from any of the external memory medium. Thus, any failure occurring while booting a 2-stage loader from one external memory can be recovered by booting from another external memory medium.

Knowledge Bytes
What is Android CTS?
- Android CTS (Compatibility Test Suite) is an open-source, commercial, and automated test suite, provided by Google. This test suite for Android applications is an automated “mechanism” to test compatibility of a particular Android application during the development process.
- Android CTS consists of a number of test cases, that can be used to evaluate the software and hardware components of an Android device. Android CTS helps in detecting all Android incompatibilities during the development phase itself.
What is Android Automotive?
- Android Automotive is an Android-OS based platform that executes pre-installed In-Vehicle Infotainment System applications. Android Automotive provides an open-source codebase for automotive infotainment that is completely free of cost. It can be directly installed on the in-vehicle hardware. Automotive software engineers can also customize and implement new features on the platform to develop unique products.
- One of the many advantages of using Android Automotive for Infotainment system development is the fact that software engineers have access to a huge repository of reusable software created by Android developers worldwide. Development expertise and guidance is also available easily.
