Boot loader is the basic building block for a long life and reliable functioning of any embedded system. Maven understands the critical components involved in developing a boot loader and has the desired expertise to develop a boot loaders capable to perform POST, image check, memory check and testing of critical peripherals of system. Maven has developed a variety of boot loaders best suitable for the operating system and functional requirement of the system.
Maven has done development for u-boot for Linux systems, VxWorks boot loaders, e-boot for Windows compact and CE6 and custom boot loaders for firmware enabled devices.
Maven has developed boot loaders to boot image from flash, USB, serial and SD card. Maven has specialization to support remote firmware upgrade and firmware redundancy in boot loaders.
Selecting a right operating system is extremely important to meet the functional requirements and overall performance of the system. At Maven, we consider various factors such as processor capability, memory footprints, performance, power requirements and time to market.
Maven has extensive expertise in BSP development, porting and customization for different operating systems and develop device drivers for peripherals on these operating system.
The broad spectrum of BSPs developed by Maven include:

Low memory foot-print data structures and programs are developed for controlling various peripherals. The hardware abstraction layer (HAL) contains drivers developed for interfaces such as RFID readers, Bluetooth, Wi-Fi, Ethernet, Weigand readers, USB host and device, UART, RS485, battery, LCD, keypad and IOs, touch screen and storage devices. Firmware development for different family of microcontrollers such as Microchip PIC (PIC18, PIC24, and PIC32) and LPC series is done. These are primarily used in logistics management, location identification and asset tracking applications.
SPI, I2C, UART, RS485
Display options such as LED, character LCD, graphics LCD and TFT LCD display are used to suit product requirements. High end devices with TFT color LCD with touch screen are used with applications such as video streaming and audio-video communication with VGA and QVGA resolutions. Industrial HMIs / MMIs, security solutions and driver consoles are developed using high resolution – industrial grade displays.
Maven has developed drivers for firmware to support range of LCDs including character LCDs, graphic LCDS and TFT LCDs. Maven has also ported and customized drivers for Linux based TFT LCDs. Touch screen and keypad interfaces are provided as user touch points. Drivers for various touch screens and IO based keypads are developed at Maven.
Internal and external ADCs are used in solutions for industrial and home automation. If the resolution supported by internal ADCs is not sufficient, higher resolution external ADCs (16, 18 or 22 bits) are used. Drivers for architectures such as ‘Delta sigma’ and ‘SAR’ are supported depending on internal or application level sampling.
Maven provides advanced ‘Power Line Communication’ solutions for retrofit solutions. RF or WiFi based networks have penetration problems through concrete walls or have issues over long distances. Sometimes wiring infrastructure becomes a problem as adding new communication back-bone to already available concealed wiring is near to impossible and a costly affair. These issues are tackled with PLC based solutions. These types of problems are typically observed in cold storage plants or existing facilities which need BMS solutions or places where industrial automation needs to be implemented. Maven’s PLC to wireless gateway proves to be a great advantage in such situations. Maven has developed firmware based solutions like PLC to RF, PLC to Ethernet and PLC to serial gateways.
Firmware based drivers are developed for internal flash, EEPROM, external data flash, microSD card, standard SD card, USB mass storage, and hard disk. For high-end applications, Linux and WinCE based drivers are ported for USB SATA hard disk and USB mass-storage.
File systems such as FAT-32, NTFS, EXT-2, EXT-3, JFFS2, UBIFS, CRAMFS have been ported for Linux. FAT, TFAT and NTFS file systems have been ported for WinCE.
MEMS - Accelerometer, Gyroscope, Magnetometer
MEMs sensor based devices / accelerometers are used in various solutions which need sensing of directions using ‘dead reckoning’ techniques in absence of GPS. Vertical falls or crash can be determined using these devices. In healthcare area these prove extremely useful for devices used in monitoring old people or patients. Drivers for Freescale MMA7455L have been integrated in all solutions.
Home safety & security – door, motion, fire, smoke, temperature, RFID
RFID based solutions are developed for reading active and passive RFID tags. Firmware for RFID (TRF79xx ISO 14443 A/B, ISO 15693, ISO 18000-3) has been developed to read RFID tags.
Industrial – fuel, load sensor, RPM, level
Drivers for USB 1.1, 2.0 and OTG support are developed / ported for various microcontrollers and processors. USB host support is provided for connectivity with mass storage devices, printers, etc. USB device support is provided for debugging and device charging. Solutions with multiple USBs with and without DMA support are integrated.
Maven has integrated CCD cameras in high end security solutions with video surveillance. Maven has developed driver for 4-channel NTSC / PAL video decoder (TVP5158). Single camera is displayed using VGA resolution on LCD monitor and multiple cameras using QVGA resolution. TI DM365 based processor is used for a solution to capture streams from a CCD camera with VGA resolution and transferring streams over Wi-Fi. Video based application development is done using specific codec plug-ins like H264 and MPEG4. Audio codecs such as G.711 are integrated.
Wi-Fi solutions with support for 802.11 b / g / n are designed considering factors such as range, number of nodes / traffic and type of data to be transferred. Wi-Fi drivers are developed for firmware based solutions used in home automation and security solutions. Wi-Fi drivers have also been ported on Linux and WinCE platforms with high bandwidth requirements for audio video streams transfer. High data rates have been achieved using throughput optimization techniques.
Mobile solutions have become an integral part of all the devices used in real-time tracking, monitoring and control. To ensure fail safe communication, dual SIM card facility is provided. GSM, GPRS and 3G based communication mechanisms are used to support different application needs such as only data transfer or supporting multimedia streaming protocols. Modems from Simcom, Centerion, Telit and Wavecom are supported.
GPS solutions are used for fleet management and individual / logistics / asset tracking requirements. Interfacing of GPS modules from Skytraq, Venus, LeadTek – SiRF STAR III/LP, Ublox 5 has been successfully done at Maven.
On Ethernet and Wi-Fi
Also mention about porting to FreeRTOS
Support for low and high frequency RF modules is made available for different applications. 2.4 GHz, 433 MHz, licensed and open frequencies are used for applications needing wireless communication with different range requirements. Firmware applications are developed to support updating change of parameters and bulk data transfer over custom protocols. Special care is taken for power management and data is transferred in bursts or only when needed. RF repeater modules are designed for signal amplification to cover long distance communication and RF mesh networking solution. RF to PLC and RF to serial gateways are developed for communication between different mediums.
ZigBee modules are integrated in home / office / industrial automation solutions. ZigBee protocol implementation for sensor communication and mesh networks has been developed.
Bluetooth based solutions are used for connecting mobile phone applications for quick display and easy access of information of data from data loggers and controllers. Firmware for Bluetooth modules from CSR are integrated with solutions for data centric or device controlling industrial applications with support for services such as file-transfer and Obex.
Power management firmware is developed to provide fine level of control over individual devices such as displays, disks, modems, Wi-Fi, processor or any of the peripherals. Use of accelerometer, timer and other algorithms ensures extraordinarily long life on battery power.
Multimedia and user interface applications on Linux (based on DM368 or DM365) are developed by taking advantage of the hardware acceleration and software frameworks such as Linux GStreamer and TI’s digital video software development kit (DVSDK) Rich UI and video based application development is done using QT and specific codec plug-ins like H264 and MPEG4.
