What We Do

At Promwad, we provide a wide range of kernel engineering services to enhance your product's performance and reliability.

Board support package (BSP) development

 

Our embedded Android & Linux Board Support Packages (BSP) development includes:

  • Creation of BSP with boot loaders (U-Boot, custom).
  • Development of drivers, protocol stacks, and system interfaces.
  • Development of power-on self-test sequences.
  • Creation of file system images.
  • Profiling and code optimisation.
  • Documentation development.
  • Contribution to mainline open-source projects.

Drivers and BSP development for Android

 

We develop drivers and BSP (software modules or collections of modules) for Android, specifically designed for different processor architectures. Our expertise lies in modifying and configuring the Android kernel to ensure support for all features of a specific hardware platform.

 

Developing and porting middleware

 

We develop middleware, the linking software that connects different apps, systems and components, using technologies like XML, SOAP, web services, and service-oriented architecture. 

Our team has experience in porting middleware into solutions within the following areas:

  • Streaming audio and video
  • Graphics libraries and app
  • User libraries
  • Open source software
  • Networking applications
  • Development tools
  • File system and flash utilities
  • Real-time tools

Assymetric multiprocessor processing (AMP)

 

We utilise asymmetric multiprocessing, where multiple operating systems run on a multi-core chip. One core runs Linux, managing data transfer, protocol support, and user interface access. The other core executes a real-time operating system (RTOS), handling real-time processes.

 

Linux device driver & kernel development

 

What we do within our Linux kernel and driver development services:

  • Develop drivers for x86, ARM, RISC-V, PowerPC, SPARC, and other processor architectures.
  • Build file systems from scratch and modify existing ones.
  • Сonfigure task scheduling and management system.
  • Build a networking stack.
  • Engineer-specific codes for low-level architecture.
  • Perform device tree configuration.
  • Set up memory management systems.
  • Develop framebuffer, V4L2, and USB interfaces.

We assist customers in adapting Linux kernels to hardware platforms and developing drivers for essential peripherals such as audio, graphics, RTC, NAND, sensors, data exchange, and power.

Optimisation

 

During our technical audit of Linux-based client systems, our team:

  • Identifies vulnerabilities and addresses them to enhance system security.
  • Reduces energy consumption and system start-up time.
  • Optimises processor performance for improved efficiency.
  • Enhances the operation of RAM, ROM, and flash memory to improve overall system performance.

Android kernel driver programming

 

We develop custom drivers for the Android kernel to simplify application integration and ensure hardware compatibility. Our services also include the following:

  • Integrating peripherals and off-the-shelf components.
  • Engineering and integrating hardware.
  • Designing user drivers and loaders.
  • Conducting testing and validation.
  • Implementing Android OS versions.
  • Developing custom Android ROM.
  • Assisting with migration to/from Android OS.

Linux system design

 

What we do within embedded Linux system design services:

  • Cloud integration
  • OTA updates
  • OS migration
  • IoT and embedded security implementation
  • Customisation of Linux distributions
  • GStreamer-based video and audio software solutions development

FAQ

How do you approach compatibility and customisation in Linux kernel programming?

 

We thoroughly analyse our client's hardware specifications and the overall functionality of the solution. Thus, we ensure the kernel is tailored to the specific hardware platform, optimising its performance and ensuring seamless integration into your infrastructure.

 

How can embedded kernel development enhance the performance of my Linux system?

 

Kernel plays a crucial role in enhancing the performance of your Linux system. By optimising the kernel configuration and fine-tuning various parameters, we can maximise resource utilisation, reduce latency, and improve overall system responsiveness.

We also leverage kernel-level optimisations, such as implementing efficient memory management, I/O scheduling algorithms, and power management techniques, to achieve optimal performance for your specific use case.

 

What level of support and maintenance do you provide for embedded Linux kernel development projects?

 

For our clients, we provide comprehensive support and maintenance services before and after the deployment stage. Our team ensures that your kernel remains up-to-date with the latest security patches and bug fixes, minimising vulnerabilities and enhancing system stability.

 

How do you ensure scalability and reliability in Linux kernel module and device driver programming for large-scale deployments?

 

By carefully designing the system architecture, we ensure that it can accommodate increased workloads, handle concurrent processes, and scale seamlessly as your requirements grow.

We implement fault-tolerant mechanisms, such as redundancy and failover support, to enhance system reliability and minimise downtime. Additionally, our engineers test and optimise performance to identify bottlenecks that need to be “expanded" to guarantee the scalability and reliability of your kernel system.

 

What is the relationship between a kernel system and device drivers?

 

They are closely related components of an embedded Linux system:

  • The kernel is the core software that manages system resources, provides abstractions for hardware devices, and handles low-level operations. 
  • Device drivers, however, are software components that facilitate communication between the operating system kernel and specific hardware devices. They enable the kernel to control and interact with various peripherals, such as network interfaces, storage devices, and input/output devices.

Proper integration of device drivers within the kernel system is crucial for seamless hardware functionality and efficient system operation.
