Embedded Linux Development

Over the years ALTEN Global has grown to provide support in the creation of embedded software systems.

ALTEN Global has an in-depth experience of Customization of Embedded Linux Operating System for any platform or hardware board, and also Embedded Linux Application development. This includes Linux Kernel BSP/Driver customization. Accord’s engineers are experienced on Standalone Linux, SDK Linux, Embedded C, Build Root, etc.

ALTEN GT expertise is in product development on SoC and SOM platforms with display interfaces, communication interfaces, sensors, peripherals, network protocols and implementation of features like embedded device security, secure communication, differential firmware upgrade etc.

ALTEN GT teams have command over full embedded software life cycle beginning with requirements analysis, System Architecture development through code development and integration testing. ALTEN GT also specializes in custom board bring-up for a variety of architectures including ARM. Accord’s board bring-up services range from setting up and booting the board from sources like eMMC, NAND, SD card, etc. to setting up the bootloader, kernel and optimizing for various devices and peripherals.

ALTEN GT provides complete end-to-end device security and implements security early in the device design phase and maintain the security of the software right through product deployment. ALTEN GT ensures that the device is not running tampered software by verifying its authenticity before execution. Accord’s secure boot/chain of trust service establishes the software authenticity from bootloader to user applications. Accord’s security service helps in determining how to update/deploy software securely and deny unauthorized software installs. ALTEN GT is skilled in modifying and customizing Linux kernel and Linux kernel drivers for IoT solutions, industrial automation, etc.

ALTEN GT also specializes in integrating embedded Linux devices with the peripherals on custom boards, as well as develop user-space drivers for end-user and GUI apps. ALTEN GT also provides sound recommendation of hardware component/selection to reduce costs and development efforts.

At ALTEN GT, we make it a point to listen to our clients’ needs and technical requirements completely to create a product that is specifically tailored for the customers.

Embedded Linux Product showcase

Telematics Control Unit (TCU)

Telematics Control Unit functions as a communication unit between vehicle and the User interface through the Cloud. TCU is a main stakeholder of connectivity solution and it will be acting as a data logger and gateway. Major functions of TCU will be Location gathering, vehicle information gathering and transferring to the Cloud. The TCU is developed as Platform and has different components like GPS, GSM, Wi-Fi, Bluetooth, Memory, Accelerometer, RTC, Internal Battery, SIM card etc.

Micro Air Vehicle (MAV)

This project aims at developing RF modems which can be used in an MAV application for video recording and down streaming purposes. The airborne unit is responsible for collecting the compressed video from the on-board camera unit and telemetry data from autopilot of the MAV, record it and then downstream it to the Ground unit at S-band frequencies. It is also responsible for receiving the control commands sent by the ground unit and pass it onto the autopilot of the MAV.

Network Time Server (Clock)

It is a GNSS based Network Time Server from ALTEN GT which is also a source of highly stable and accurate time (nano second accuracy) and frequency source. It comes fitted with Our GNSS receiver capable of receiving and tracking signals from GPS, SBAS (GAGAN), GLONASS (optional) and Dual frequency IRNSS (optional). This product has multiple GbE ports for time dissemination over the network using NTP protocol and PTP protocol.

NavIC Receiver Monitor

This product is a NavIC (IRNSS) GPS SBAS Receiver. It has features like Data logging, Data Transfer, Displaying receiver parameters, security related features and Remote monitoring of Receiver Status data.

Smart Surface Control Unit (SSCU)

The Smart Surface Control Unit is a line replaceable unit of the Smart Surface System and provides Video Signal, Control Information and Power to the connected Display or Projector. It updates internal media and configuration databases by automatic file transfer from a USB storage device. Play still and motion pictures with support for “Warping” feature. Projector functionalities like power on/off and light output. The connected projector will be commanded via a serial interface. UDP interface that allows to select different scenarios (0-9) in terms of videos or pictures (e.g. Scenario 1: Sunrise-Movie, Scenario 2: Cloud-Movie etc.)
