Xilinx PTPv2 usage

Former Member

Hi.
I want to use the PTP project from xilinx. http://www.wiki.xilinx.com/Zynq-7000+AP+SoC+IEEE1588+v2+Precision+Time+Protocol+Tech+Tip
After recompiling the kernel I do not know how to integrate or what exactly to do.
Does anybody know, or has anybody implemented the PTPv2 yet?

How can I use the user applications or how can I get them.
The image on the predefined holds an elf file for but no sources.

I need to extend the functionality, so I need the sources themselves.

Thanks in advance.

    I downloaded the LinuxPTP from git and tried to compile it, but without any success.
    I get one Error :

    sk.c: In function 'hwts_init':
    sk.c:55:30: error: 'HWTSTAMP_TX_ONESTEP_SYNC' undeclared (first use in this function)
    sk.c:55:30: note: each undeclared identifier is reported only once for each function it appears in
    make: *** [sk.o] Error 1

    So I had a look at the source file sk.c at line 55:
    tcfg.tx_type    = one_step ? HWTSTAMP_TX_ONESTEP_SYNC : HWTSTAMP_TX_ON;
    and at the include files:
    #include <errno.h>
    #include <./linux/net_tstamp.h>
    #include <./linux/sockios.h>
    #include <linux/ethtool.h>
    #include <net/if.h>
    #include <netinet/in.h>
    #include <string.h>
    #include <sys/ioctl.h>
    #include <unistd.h>
    #include <ifaddrs.h>
    #include <stdlib.h>
    #include <poll.h>
    I couldn't find net_tstamp.h neither ethtool in my XilinxLinux sources

    The xilinx_emacps.c File, which is necessary to modify for hw timestamping  does contain HWTSTAMP_TX_ONESTEP_SYNC


    There is only the enable of HWTSAMP... starting at line 2600:
    #ifdef CONFIG_XILINX_PS_EMAC_HWTSTAMP
    static int xemacps_hwtstamp_ioctl(struct net_device *netdev,
    ttttstruct ifreq *ifr, int cmd)
    {
    tstruct hwtstamp_config config;
    tstruct net_local *lp;
    tu32 regval;

    tlp = netdev_priv(netdev);

    tif (copy_from_user(&config, ifr->ifr_data, sizeof(config)))
    ttreturn -EFAULT;

    t/* reserved for future extensions */
    tif (config.flags)
    ttreturn -EINVAL;

    tif ((config.tx_type != HWTSTAMP_TX_OFF) &&
    tt(config.tx_type != HWTSTAMP_TX_ON))
    ttreturn -ERANGE;


    So, how can I enable HWTStamp for LinuxPTP project? Which sources do I have to include instead?
    Thanks in advance
