Bootloader Software Development Project for Seating Control Application

Customer:

An US based Tier-1 supplier of automotive and industrial thermal products.

Their pursuit of Innovation has helped to develop niche in domains like aviation, medical, home and office appliances.

Business Challenge:

• Our customer’s team was working on a tight deadline. In the application development phase, the significance of bootloader solution was realized. Bootloader software was initially not a part of the software development roadmap.
• Customer also realized that the in-house expertise did not offer skill-sets required for bootloader software development.
• Development of bootloader software also required specialized skills and experience in Vector tools

Embitel Solution:

• Our team of automotive software developers developed a Vector FNOS bootloader solution.
• This bootloader software was designed using Vector Geny tool for the seating control application. This seating control system is designed to support Climate and Motor control features.
• The Vector FNOS bootloader has been customized to adapt the seating control application
• A gateway re-programming software was developed over SPI protocol for the non CAN network based microcontrollers on the ECU PCB
• This gateway software acts as a bootloader for the microcontrollers which are not connected to vehicle CAN network.
• The gateway helps the non CAN or SPI network depended controllers to communicate with the CAN based network which in turn communicates with the Vector FNOS bootloader.
• Our team also developed a bootloader re-programming utility, which is a web-based application designed on UDS(LIN) protocol using CAPL and CANoe scripting.

Why Tier-I supplier partnered with Embitel for Vector FNOS Bootloader development?

• The business requirement of the client was complex and needed and lot of understanding about their end application.
• Reason being, the application was already in the development phase when the requirement for a compatible FNOS bootloader was brought to our desk.
• Embitel’s embedded software team won the confidence of the customer during consulting workshops.
• Customer also realized the value-addition of our 10+ years of domain expertise in automotive embedded software and experience in Vector tools

Embitel Impact:

• Our expertise in embedded system software development helped our customer’s R&D activities to be more focused on application development.
• Domain expertise of Embitel in Bootloader programming and vector tools such as CANoe and CAPL guaranteed the customer with quality delivery
• Such business solutions resulted in effective cost efficiency and reduce the time-to-market for the customer.
