<< UDS Bootloader <<


An increasing number of ECUs need bootloaders to update firmware in the field via CAN. The use of a complete UDS stack for the bootloader is mostly unsuitable, because of the large flash memory footprint.
Emotas has developed a new UDS Bootloader 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 UDS compatible.

The UDSonCAN 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.

UDS services and limitations

If additional UDS services or specific "update sequences" are required, we offer an extension or customization of the bootloader according to your requirements.
