CAN support / Autosar

[Anna]

On the Wiki there is a section about support for Autosar drivers. But the link does not work. I cannot find any further documentation on the support for automotive grade stacks. Can you elaborate on this? What sort of CAN support (if any) is there in ERIKA?

Dear Anna,

Thanks for your e-mail...

We have some initial versions of drivers implementing the AUTOSAR API.

Some description is available at the following link:
http://erika.tuxfamily.org/wiki/index.p ... AR_Drivers

We are also going to fill this page
http://erika.tuxfamily.org/wiki/index.p ... ke_Drivers
soon with more information during this week.

In any case, the drivers are available currently for Cortex M4 TI Stellaris and Renesas RX200.

There is no AUTOSAR CAN Driver equivalent, as noone so far requested it or committed resources on doing one... I remember there was an initial effort in the univ. Lab about the can driver for dspic, but at the ened it was not committed.

Which is the architecture you are interested in?

Regards,

Paolo

Hi Anna,

so far, there is no Autosar CAN driver support. An initial effort has been done at Retis Lab during my Ph.D. Basically a standard CAN Driver for a DSPIC has been wrapped by a primitive AUTOSAR CAN driver (ONLY CanDrv layer, No Can Interfarce (CanIf), No Autosar Callbacks, No static configurations examples or CAN-Driver upper layers have been developed).

Thanks very much for your replies. I'm interested in support for a Cortex-M3 based system. Is there a timeframe for when this is (planned to be) ready?

[fesposito]

Not yet planned for any Cortex M3.

But consider that CAN Driver (the lower layer) is MCU-specific and not to CPU-specific. Hence it depends on which MCU you chose for your Cortex M3 (e.g. TI, Freescale, ST, etc).
