Software residing on ECUs needs to be regularly updated not only during development but also after production and throughout the vehicle’s lifetime. EB tresos Bootloader enables car makers to securely update the software of Classic AUTOSAR & OSEK ECUs inside a vehicle using a downloading tool, which is connected via a communication bus (Ethernet, CAN, LIN, FlexRay) to the vehicle using the standardized UDS protocol from ISO 14229. This allows car makers to easily update the ECU during software development and add additional features for the application while reducing costs and efforts. EB delivers a fully integrated and tested EB tresos Bootloader that includes a demo configuration on the project hardware/compiler. When ordered, features of the EB tresos Bootloader such as memory mapping and communication identifiers are configured according to project requirements. This enables car makers to execute a complete programming sequence to download an application demo software on delivery of the product.
Update ECUs during development phase and manufacturing and when the vehicle is on the road. This reduces the costs and efforts to manually fix a faulty ECU.
Secure boot and secure update features use state-of-the-art security algorithms to verify the authenticity and integrity of the software (BootManager, Bootloader, and/or Application) that runs on the host. SecureBoot architecture is based on EB tresos Bootloader and EB zentur HSM Firmware products
Available in series production quality.
