Android And Linux Porting Services For Embedded Systems
Porting of Android or Linux in Embedded Product: Advantages and Best Practices
Porting of open-source Linux and Android for embedded product development, instead of porting a proprietary operating systems offer several advantages.
Following are some of the advantages:
- Android and Linux OS is GPLv2.0 licensed. This means these are open-source software and hence one ends-up saving licensing cost
- 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 customisations
Before kick-starting your Android or Linux porting projects following are some of the best practices your embedded software development partner should take care of:

Creating Linux Distribution Image with Yocto:
What is YOCTO?
The Yocto Project (YP) is an open source collaboration project, under the aegis of the Linux Foundation . It simplifies the process of custom building Linux distributions for embedded and IoT applications , independent of the underlying hardware architecture. The Yocto Project provides built-in toolchains, software stacks, board support for multiple architectures like ARM, MIPS, PPC, x86, x86-64 & more, configurations, emulation environment etc.
What are the steps involved in custom development of an embedded Linux Image, using the Yocto Project?
