OS Porting & BSP Development

Faststream Technologies is expertise in OS Porting and BSP Development of  Board Support Packages for operating systems over various microcontrollers and microprocessors. We have worked extensively on configuring the BSP to support operating systems features, file systems, and memory types. We provide optimization and development services for boot loaders, file systems, and device drivers as well as Board Bring up and RTOS Porting Services. We have good knowledge of OS Porting, optimization, and customization of boot loaders and file systems like FAT16, FAT32, JFFS2, YAFFS.

BOARD BOOT UP

We have deep domain knowledge of ARM cores and memory architectures that aids in the rapid boot-up of new boards. We have worked on different kernel versions on Linux and Android which helps in porting BSP from a specific kernel version. We stick to the mainline kernel of a silicon vendor to achieve a stable version of ported BSP. We also offer customization of the Android Hardware Abstraction Layer for delivering numerous non-default Android features.

FASTER BOOTING AND POWER OPTIMIZATION

Faster booting with minimum power consumption is needed in many devices used in Automotive and handheld devices. We provide services on optimization of Android and Linux boot time through entire system analysis. For optimization of boot time, firstly we get the platform for which the optimization has to be carried out, get the current statistics and optimize it to get values near to theoretical number.

APP DEVELOPMENT

Our application services are based on QT and GTK based GUI applications, Android applications, etc. We have worked on the integration of camera imaging sensors to the embedded platforms and offering solutions on ISP tuning and image quality.

OS Porting / BSP Porting AND DEVELOPMENT

 

We have extensive knowledge in designing, implementing, and debugging Board Support Packages (BSPs). Our firmware knowledge along with our reference BSPs enable us to port an OS on a board to estimate its potential and to lessen the time period to develop an OS-based device.
We have worked in embedded OS platforms like Windows Embedded suite, Windows Mobile, and embedded Linux. We also have knowledge of the processor architecture of PPC, NIOS, ARM, ColdFire, and x86 which has enabled us to master technical skills in developing bootloaders that helps in the fast download of new OS images during the development phase. Also, it has helped us to develop the architecture code that allows communication between the OS kernel and device. It also includes creating device drivers to support peripherals onboard device interfaces such as touch screen, keyboard, audio to function suitably between devices.

 

OPERATING SYSTEM PROFICIENCY

 

Android, Linux, WinCE, Linux as well as RTOS like QNX, uCOS, FreeRTOS, etc are the embedded OS our team has been working on.

 

TECHNOLOGY SKILLS

 

We are skilled in technologies like SMP, AMP, ARM Hypervisors, and Virtualization.

We provide development of boot loaders, device drivers and middleware.
