UDS Bootloader

The Simma Software UDS bootloader is a complete software package that allows users to update the firmware of an embedded ECU. This package comes with two main components: target-specific code that resides in the embedded microcontroller and a PC-side host application called flashUDS (versions supporting both Windows and Linux are available). Various ISO 14229 (UDS) services are used to execute the flash updating process. OEM flash updating specifications as well as enhanced security requirements can be supported.
