GPIO/CAN Pins on ZedBoard

Please forgive me if this question has already been answered elsewhere. I have a ZedBoard on which I am developing, and I require integration with a CAN bus. The ZedBoard does not appear to break out the CAN bus.

I have, however, seen several posts on this forum about operating the CAN bus on a ZedBoard. Some people seem to have been operating CAN over GPIO pins.

Are there any exposed CAN pins? Are there any exposed GPIO pins that can be used to implement CAN over GPIO?

Thanks

Most of my experience is with the Vivado GUI but I think you will be using tcl from the command line. As this Answer Record suggests ( http://forums.xilinx.com/xlnx/board/crawl_message?board.id=Vivado&message.id=1820 ) Xilinx Users Guides UG834 and UG894 are probably a good place to start.

You might also want to take a look at the TCL Community on the Xilinx Community Forums: http://forums.xilinx.com/t5/Vivado-TCL-Community/bd-p/Vivado

If you do a search for "vivado command line" also turns up some interesting answer records.

Perhaps some other forum members have more command line experience to relate.

Gary,

There seems to have been a miscommunication. I'm not looking for a way to configure a project on my laptop, I'm looking for an instruction that can be executed by the arm core itself.

ie:

minicom -D /dev/tty.usbmodem...

-- OR --

ssh root@my-zedboard-running-ubuntu

root@my-zedboard-running-ubuntu ~ $ some-awesome-binary show-mio-status
...
...

root@my-zedboard-running-ubuntu ~ $ some-awesome-binary set-mio-pin --mio=14 --tgt=can-0-rx
root@my-zedboard-running-ubuntu ~ $ some-awesome-binary set-mio-pin --mio=15 --tgt=can-0-tx

The TCL scripts seem to be geared towards interaction with the development environment rather than with the production environment.

Do you think Xilinx included such an instruction, or DMA memory address, or ... to allow the ARM to configure the MIO pins?

Thanks again for helping,
Harrison
