Weird. That is really, truly broken. > Based on the location of the jump I would venture to say it is not > an issue in the FPGA hardware but rather something within the > ARM/OS. Do you know what could be causing the jumps? You didn't mention the FPGA/IP core you are using. I'm willing to bet the bug is in there. [ No need to embarrass anyone. So many buggy IP Cores in this world. It could make someone cry. But not me, I'm used to it by now :( ] Thanks, Richard _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
