emtas CANopen Bootloader
Software package of a CANopen Bootloader including Flash Firmware Updating
To avoid this waste of flash memory, emtas developed a new CANopen Bootloader that needs only few memory resources. The bootloader supports the necessary services (SDO, NMT slave, heartbeat producer) and objects. So resource saving 6 to 8 KiB of flash memory are sufficient for the emtas bootloader – and it is still CANopen compatible.
- Segmented SDO Transfer
- SDO Block Transfer
- Only little flash resources needed
The CANopen Bootloader is available for different 16- and 32-bit microcontrollers and can easily be adapted to other targets. SDO block transfer is optionally availabe as well. 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.
The CANopen UpdateManager is an easy to handle tool designed for firmware downloads. Apart from direct firmware downloads it offers the opportunity to put firmware files for all devices of a network together, add the configuration data and and create an update package.
This allows service technicians to carry out an automated update of all devices in a network that need an update by simply starting the update package. Additionally, both a CAN backdoor and access to second domain is supported.
Supported processors and IDEs
For this CANopen Bootloader, target hardware with CAN controller is required. The CANopen Bootloader can be used with for example compilers or IDEs of GCC / GNU, Keil, IAR, Crossworks, Atollic True Studio, Tasking and the specific development environments of the various chip manufacturers.
Ask for the specific possibilities of a specific controller / IDE combination.
The CANopen Bootloader is delivered as source code in the form of a one-time Project or Site License. The distinction between them is as follows:
- Project license
The software (source code) may be used at one defined development location for one defined project. The default support period is 6 months.
- Site license
The software (source code) may be used on one development site / location, by various developers at this location, for an unlimited number of products. The standard support period is 24 months.
There are no run-time fees or royalties on the generated object code.
