Lost frame on AM3359 ICE board ethercat example

HI..

now days I'm testing my ICE board as etherCAT slave..

so I just add some index for ethercat Object Dictionary.. and I maped that object to PDO (0x1602) 

I thought it works properly... but there is Lost Frame error in OP mode (ethercat state machine)

so i'm trying to find out what is problem...

and I found  EtherCAT example from TI has no Lost Frame.. so I just changed size of existing index(0x7020 Motor output count & cmd)  8 bit -> UINT16

and now I can still see Lost Frame on Twincat 2 

what is problem ?? ind_sdk_1.0.0.5 has problem??

Or is this bug of PRU firmware ??

please help me.. below is my capture file..

thanks in advance..

    Moonseon,

    you should always use the latest IA-SDK of course. we are now at 1.0.0.8. Still I believe that is an issue of your application software not matching the device description. We have tried several different object dictionary configuration in our examples, demo and customer examples. If done right it will work with TwinCAT. You may also try CTT to see if this gives any hints. Generally I would like to defer you to the EtherCAT forum on ethercat.org for such issues. There are real EtherCAT experts who can help on the object dictionary setup and appropriate device config creation.

    Regards,
