CAN Controller header files

hjo

Can someone please help regarding the C header files I have to use for developing a CAN driver for the Zynq internal CAN.
I'm confused. Is it
canps_v1_00_a/
canps_v1_01_a/
can_v2_00_a/
?

I'm even not sure if it is a LogiCore IP or any other.
The CAN Controller itself is documented in Zynq-7000 EPP Technical reference Manual UGS85 Chapter 18.

I hope you can send me with a link to the directory within the EDK. Thanks.

    With the help of friends at Silica Berlin I got can4linux working. The project is at http://sourceforge.net/projects/can4linux/

    Hey,
    I want to compile the can4linux for my Zedboard but when I use the ./target zedboard, the next message appears:

    elect Target compilatiion environment
    ======================================

    ./target <target>
    where <target> = standard | mcp2515spi | mcp2515 | mcp2515aur | mmc | at9263
                     | imx25 | imx28 | imx35

    mcp2515spi - with external MCP2515 using kernel SPI driver
    mcp2515    - SSV ATMEL9263 with external MCP2515, direct SPI register acc
    mcp2515aur - A&R ATMEL9G45 with external MCP2515, direct SPI register acc
    mmc     - Heyfra MMC, ATMEL AT91SAM9260, 3 external SJA1000
    at9268  - ATMEL AT91SAM9263 internal CAN controller
    imx25   - Freescale FlexCAN iMX25 (Ka-Ro TX25)
    imx28   - Freescale FlexCAN iMX28 (Ka-Ro TX28)
    imx35   - Freescale FlexCAN iMX35 (Freescale PDK)
    zedboard- Xilinx Zynq on ZedBoard
    standard- local host PC, using the local kernel source tree
              call 'make TARGET=X' for different supported boards
              call 'make help' for a list of supported boards

    the script does: ln -s Makefile-zedboard Makefile
    before calling make, adjust cross-zedboard and source it in

    ARCH             arm
    CROSS_COMPILE    arm-xilinx-linux-gnueabi-
    CC               /home/user/bin/arm-xilinx-linux-gnueabi-gcc
    AR               /home/user/bin/arm-xilinx-linux-gnueabi-ar
    LD               /home/user/bin/arm-xilinx-linux-gnueabi-ld
    RANLIB           /home/user/bin/arm-xilinx-linux-gnueabi-ranlib
    DEPMOD           /home/user/bin/arm-xilinx-linux-gnueabi-depmod-2.6
    KDIR             /usr/src/linux-headers-2.6.3246-generic
    LIBS           
    CFLAGS           -Wall -Wstrict-prototypes -Os -Wl,-s
    LDFLAGS        
    DEPLOYDIR      
    DESTDIR          /home/user/Escritorio/can4linux/can4linux-4.1

    ===================================================
    NOW do:
    $ unset KDIR
    $ . cross-zedboard

    I think that the problem is about cross-zedboard file configuration. In the cross-zedboard configuration I have a question: where is located linux directory due to the next directory doesn't exist.

    [ ${KDIR} ] || KDIR=/home/oe/development/zynq/linux-xlnx

    Has somebody the can4linux compiled (can4linux.ko) or has any idea about what I can change to compile??

    Thanks.

    regards.
