<< J1939 Bootloader (CAM11/CAM21) <<


An increasing number of J1939 devices need bootloaders to update firmware in the field. The use of a complete J1939 stack for the bootloader is mostly unsuitable, because of the large flash memory footprint.
Emotas has developed a new J1939 Bootloader using CAM11/CAM21 that needs only few memory resources. The bootloader supports only the necessary services. 16 KiB of flash memory are sufficient for the emotas bootloader – and it is still j1939 compatible.

The J1939 Bootloader is available for different 16- and 32-bit micro controllers and can easily be adapted to other targets. It is delivered as ANSI-C source code and thus can be extended by customers e.g. with a password protection mechanism, firmware encryption or a manufacturer-specific back door.
