vFlash - Programming ECUs over CAN, CAN FD, FlexRay, LIN or Ethernet

vFlash is designed for all users at automotive OEMs and suppliers whose tasks include (re-)programming of ECUs. It supports already more than 70 different flash specifications and is simply expandable via a plugin concept.

Advantages

Flashing via CAN, CAN FD, LIN, FlexRay, Ethernet (DoIP, SoAd = AUTOSAR Socket Adaptor)
Simple exchange of pre-configured flash projects in one package (.vflashpack)
High transfer rate:
Example: transfer of 1.000 kByte data in 36,6 s (27,3 kByte/s) in idealized reference ECU over CAN at 500 kBit/s with STmin = 0, BS = 0
Support of numerous flash specifications (protocols and flash sequences) simply expandable via plugin concept with flash templates
Direct “native” programming of data in Intel hex, Motorola-S and binary format
Quick and uncomplicated creation of flash projects for different bootloader based on so-called “Flash Templates”
Flash programming based on container formats like ODX-F and OEM-specific formats
Documentation of flash actions in flash reports
Tracing of CAN raw data for later analysis in case of an error
Flashing of compressed and encrypted data
Interactive flashing via the GUI as well as automated flashing over a programming interface (C API / C# API)
Validation of the flash bootloader in the ECU in combination with CANoe.DiVa (via CAN, FlexRay, DoIP, LIN)
Standalone flashing with the Intelligent Diagnostic Device VN8810 and the “vFlash Compact” edition
Simultaneous flashing of several ECUs each on a separate communication channel with “vFlash Station”

Application Areas

vFlash is designed for all users at automotive OEMs and suppliers whose tasks include (re-)programming of ECUs. vFlash allows users to flash ECUs in the laboratory, at programming stations, at a laboratory vehicle or in the vehicle very efficiently.

vFlash can be controlled via a graphical user interface or it can be simply integrated as a library in an existing environment.
With the special edition “vFlash Station” you may simultaneously flash up to 8 ECUs each on a separate communication channel.

vFlash Bootloader Support

Vector offers prepared flash templates for a large number of different automotive OEMs and bootloaders.

Highlights Version 4

Advanced Security Features

Support of OEM-specific security mechanisms.
Optional authentication at the gateway and/or at the target ECU.
Use of different security concepts based on symmetric or asymmetric cryptography (PKI- or challenge-response-based).

Parallel Flashing via LIN for E-Mobility Applications

LIN ECUs already installed in battery stacks can be reprogrammed in parallel.
Advantage: Reduction of programming time, e.g. for 32 ECUs from approx. 2550sec. to approx. 114sec

Enhancement for Custom Actions

Custom Actions are tasks that are processed automatically before or after the flash sequence (customer scripts in C# using the vFlash diagnostic libraries).
In addition to generating reports for quality assurance, printing labels and much more, values can now also be read from the ECU and passed on to the customer application via the Automation API.

Extensions for CANoe.DiVa Flash Tests

Significant increase in speed when executing flash tests with CANoe.DiVa.

Manufacturer Support Further Extended

vFlash already supports more than 120 different Flash Bootloaders (= specifications) from various vehicle manufacturers via Flash Templates, continuously, new ones are added.
Existing vFlash templates are supplemented with new additional functions, like for example authentication with OEM-specific certificate infrastructure.

Remote Flashing

Highlights Functions

vFlash Remote gives diagnostic users the option of flashing ECUs remotely, independent of location. Users benefit from high degrees of flexibility and reliability, especially on vehicle test drives and offshore production plants.

Advantages:

Easy reprogramming of ECUs remotely - entirely independent of location and without much organizational effort or cost.
High degrees of flexibility and reliability, especially on vehicle test drives and offshore production plants.
Secure and reliable flashing procedure
Extremely easy to set up the communications infrastructure.
Users can boost efficiency and reduce costs by reusing existing flash packs for remote applications which have already been created with vFlash.

vFlash Remote will be used as the flash tool and connects to an access point on the vehicle remotely over the Internet. Two possible pathways are available for the remote interface:

Simply via the intelligent VN8810 Diagnostic Device which already integrates the vFlash Access Point
Via a Windows-based PC with an installed vFlash Access Point and network interface.

The download of the vFlash Access Point required for this will soon be available on this website.

The remote connection between vFlash Remote and the vFlash Access Point is always encrypted. This ensures that flash data cannot be seen or manipulated by third parties. Furthermore, the transfer of flash data to the Access Point is decoupled from ECU reprogramming. Reprogramming is not started until the data to be flashed has been fully transferred to the Access Point and has passed a plausibility check.

The user gets added transparency from continuous display of progress information during the flash procedure, qualified status feedback after completion and optional generation of a report for documentation purposes.

Like vFlash, vFlash Remote works with flash templates which implement the flash specifications of the automotive OEMs. Currently, more than 130 templates are available for over 70 different OEMs.

Training

The number and complexity of control units used in automobiles has increased tremendously. It is therefore important to include diagnostics in the development process of control units from an early stage.

Our training classes and workshops will provide you not only with a basic understanding of diagnostics. Especially with practical exercises you will gain a comprehensive view on the Vector diagnostic tool chain.
