Dual EVM Breakout Card

C. García
Intellectual 830 points

Hi,

I have an Dual EVM Breakout Card with the following info:

 REV: A,  LOGIC: LC_DUAL_EVM_BoC-0002, LOGIC: Rev: 10.1,

If I use tow  TMDXEVM6678L boards, the SRIO works ok.

If I use instead of the two TMDSEVM6678LE boards the SRIO does'n work.

Please, could somebody help me?

Thanks in advance.

Carlos.

    Carlos,

    The Dual EVM BOC can provide reference clocks to the EVMs.  These were not supported in the TMDX EVMs.  Make sure they are disabled and try your test again.

    Hi Tom,

    Please, could you specify what do I need to config or change in the BOC board?

    I'm using two  TMDXEVM6678L  Rev 1.0 boards and two TMDSEVM6678LE Rev 3B boards.

    I want to emphasize also the following issues:

    1.-  I have four  REV: A,  LOGIC: LC_DUAL_EVM_BoC-0002, LOGIC: Rev: 10.1,

    2.- Two of the BOC boards work ok either I connect to them two TMDXEVM6678L boards or two TMDXEVM6678LE boards.

    3.- The remaining two BOC boards work ok if I connect to the two TMDXEVM6678L boards, but doesn't work if I connect to them two TMDXEVM6678LE boards.

    Thanks.

    C. Garcia.

    C. Garcia,

    This sounds like a configuration issue.  Please make sure the jumpers on all of the CI2EVMBOC cards match.  I recall there were some issues with the RevA boards whre jumpers could be broken off.  Please refer to the documentation to make sure that they are all present.
