The boot loader software is a prevailing technology for modern System on Chip (SoC) application development. It provides some level of initialisation to the system and bridges portability to the application program. In many cases, its role is invaluable. However, the boot loader does have its set of problems. It takes up resources and requires special skills to build it. The boot loader is also susceptible to corruption due to electrical surges, bad application programs, and so on, that can render the boot loader inoperable and cause the system to fail.

Freescale, however, provides its automobile customers an alternative to custom boot loader softwarethe Boot Assist Module (BAM). The BAM provides its users two interfacesthe Enhanced Serial Communication Interface (ESCI) and the Controller Area Network interface (CAN)to upload application program using the BAM protocols. To embellish the BAM further, these two interfaces are equipped with the ability to detect fixed baud rate and automatic baud rate.
