The Flash Bootloader comprises of several device drivers and software modules for flashing the Automotive Control Unit. Let’s find out one scenario at a time! Scenario 1: An Instance of Memory Corruption by the Flash Driver We will shed lights on all these scenarios and issues that required flash bootloaders to be developed specifically to address them. There is also a possibility that the communication channel may not be secure enough, to support the re-programming. The software image (file that contains the updated version) may be large in size, or there may be a chance of flash drive corrupting the memory. Reprogramming of the Control Units Software can get tricky at times. Why Use Different Types of Bootloaders? The Scenarios and the Solutions Every scenario will be followed up by the type of Bootloader, which is designed to mitigate the mentioned challenge. The complexity of the automotive applications has also meant that one type of Flash Bootloader solution is not the best fit for all the business use-cases.Ĭhances of memory corruption and security threats has paved the way for development of flash bootloader solutions that differ based on their technology architecture, security measures and connectivity features.īefore we discuss these special types of flash Bootloader, let’s first establish their need in the context of changing automotive electronics landscape. And who empowers these software updates? It is your modest Flash Bootloader Software! The need for firmware or application update was not mission-critical, due to not-so-complex features and systems.įast-forward to the era of Connected Cars, Infotainment, ADAS and Telematics applications, and the need for frequent software updates can’t be understated. The Embedded Software Engineers, during Automotive Product Development, were more focused on the features and functions of the software. When Automotive Electronics was in its nascent stage, software engineers had not fully utilized the capabilities of a Flash Bootloader software.
