    FAQs: Board Support Package (BSP) Development

    Q. Your automotive software & hardware teams have hands-on experience with which microcontrollers for BSP development.

      Ans. Our Automotive software and hardware teams have partnered with global customers for development of Board Support Package (BSP) based on following hardware platforms:

      1. Renesas ( RL 78, RH 850)
      2. Freescale( S12G128, MPC56XX)
      3. Fujitsu, Texas, Atmel, STMicroelectronics and Cypress semiconductor.

    Q. What is our business engagement model for BSP software development ?

      Ans. We partner with our automotive customers under a one-time licensing fee model.

      Under this model, our customer gets access to the entire source code of the Board Support Package (BSP). Customer also owns the IP rights of the BSP software.

      Such a model delivers an added advantage of reuse of the BSP software modules across multiple projects (multiple platforms and/or for multiple application software).

      P.S: When you partner with us for BSP Development, we also share the static files ;viz; cfg.c and cfg.h files. This enables your team to manage the system configuration and re-use of the source code for different projects.

    Q. What programming language is used for development of BSP software? Is your code compliant with any global standard?

      Ans. Our team has in-depth expertise in Embedded C software programming language for BSP development.

      Our BSP code is compliant with 2012 MISRA C standard.

    Q. If we have a custom-developed or third party software component, can it be ported with your existing architecture without any compatibility issues?

      Ans. Yes, we ensure seamless portability of your software component module to our existing software architecture with the help of our API ( Application Programming Interfaces) based design.

      Here at Embitel, we don’t follow a coding practice that is based on global variables. Rather, we follow an API based and a layered architecture design for BSP development. This ensures that any customization or addition/removal of a software module doesn’t require major changes in the source code of that module.

      All the software modules in different layers of the BSP, communicate via APIs’ . This makes it easy for us to port your software components to our software architecture without causing any compatibility issues.

    Q. Do you provide support for both Real time Operating Systems ( RTOS) and non-RTOS systems?

    Ans. Yes, we have experienced engineering professionals who can work on both RTOS (Real time Operating Systems) and Non-RTOS based applications by following API based architecture for application programming.

    Q. What tool-chains does your team expertise in for BSP development ?

      Ans. At Embitel Technologies, we have deployed the following tool-chains for BSP development across different projects:

      1. Softune IDE: An Integrated Development Environment, Softtune is useful in developing, emulating and debugging an embedded application. The IDE is primarily used for the FR family of Fujitsu Microcontrollers.
      2. IAR: is an embedded workbench that is primarily used for RENESAS microcontroller. It includes the IAR C/C++ compiler and debugger.
      3. Greenhills: Multi IDE from Greenhills Software is used for developing BSP for PowerPC. Our automotive team has years of experience in the development and customization of BSP for PowerPC.
      4. CodeWarrior: CodeWarrior is one of the most widely used IDEs (integrated development environment) for embedded systems. It is used for editing, compiling and debugging software program for a wide range of microcontroller families, primarily the FreeScale.

    Q. Do you also offer any documentation and testing related services for BSP software?

    Ans. Yes. We offer the following documentation and testing services:

    1. Low Level Design Documentation
    2. API Documentation for software components
    3. Module Level Test Plan and Report: In order to ensure the quality of the application being developed, we perform unit testing, functional testing, and integration testing during the product development lifecycle. These tests are executed based on a test case plan and a report is generated once the tests are performed.
      • a. Functional Testing & User Acceptance Testing : If we are involved in the development for the application software, we perform the functional testing and user acceptance testing.
      • b. Manual testing: Manual testing is done for low level drivers
      • c. Unit testing/ Script Testing: The unit testing is done through the Check C framework. A script testing helps in ensuring a Modified condition/Decision coverage.
      • d. Integration Testing: If the application being developed has any additional software component, as per the user’s requirement, then an integration testing of the software modules is performed.

    Knowledge Bytes
      What is the Board Support Package?

      Board Support Package, abbreviated as BSP, is the set of software codes (for low-level drivers and hardware abstraction layer) which are essential to facilitate robust boot process of a microcontroller.

      It does not include any software other than what is necessary for the desired functioning of the peripherals of the System-on-Chip (SoC).

      As BSP is the first software code to be developed for a SoC, it also consists of the bootloader software that will load the applications in the OS memory. The board support package is also designed as per the unique specifications of a particular hardware platform and is not dependent on the OS (Operating System). With respect to the automotive embedded systems, the BSP can have varying number of CAN, PWM and ADC channels.

      What Function does a BSP perform in an automotive ECU?

      The primary function of Board Support Package is to facilitate the communication between the hardware (microcontroller) and the application software.

      To enable this, the BSP has

      • Low-level Drivers– Vehicle network drivers (CAN, LIN etc), Analog to digital converters and more.
      • Hardware Abstraction Layer– I/O handler, Pulse Width Modulation handler, communication control and more.
      • Service and Safety layers– RAM, State Manager, Fault Code Memory and Diagnostics stacks (like UDS, OBD2)
      • Scheduler and Flash Bootloader

      In an automotive ECU, the peripherals on the SOC have to interact with the OS or the Scheduler (depending on the use case). These peripherals may include USB, GPS, touchscreen and more.

      Communication between the OS kernel and the hardware component like system Bus and Memory is also taken care by the Board Support Package.

      Modules to check the ECU state, memory management and fault code memory (FCM) are all handled by BSP software.
      BSP may support additional functions as well depending on the use cases and applications.
