Re: [casper] Error reading registers with ROACH2

Tue, 12 Mar 2013 09:18:49 -0700

I'm having a hard time updating the .mdl file for tutorial1 after I tried to update to the newest CASPER tools. All the links to the yellow blocks are broken. Should the .mdl files work with the updated CASPER tools or do I have to go in and replace those blocks that have broken links? I tried doing this as well, but I can't find similar blocks in the simulink explorer. Could you send me the .mdl file for the .bof file that you sent me? Would that help? 

Thanks,

Hi Jason

Great - let us know when you have updated and tested.

    Thank you very much for the response.  The bof file you sent me
    works great.  I have not updated my CASPER tools in a while, so
    that's probably the issue.  I'll work on updating, and I'll let
    you know if I have any further problems.

    Thanks,

    Hi Jason

    Attached is a bof file I build for tut1 on Roach2, with some
    additional bus diagnostics. Please try this boffile and report back.

    Thanks

        I just loaded the latest version of tcpborphserver dated
        2013-02-12T17:00:21 for my ROACH2.  I've recompiled tutorial1
        for a ROACH2 and I'm able to load the bof file to the FPGA,
        however when I try to read a register I get a communications
        error from the Roach and the personality of the FPGA is
        dumped.  The roach is still on the network and KATCP is still
        there, but I have to reload the BOF file.  It appears I can
        write to registers correctly.  If I request say 5 bytes from
        the sys_stratchpad KATCP recovers gracefully with an error,
        but if I request 4 bytes I get the following error dump from
        the ROACH2, as read from the USB serial interface:
