I explain the steps that I followed.
* I was using the reference design for fmc110 and configuring the card via ethernet (from PC), it was working fine.
* In next step I started configuring card via pcap file (TCP replay method), still it worked fine.
* In third step I made changes in fmc110 core i.e probed out some clocks into main module, yet it was working well for some time. But with the same code suddenly the output of Channel C is disturbed. I am not sure if it is because i am using a pcap file for configuring the FMC110 card or this happened due to changes in the reference design.
Every time output of channel C is disturbed. When I rerun the pcap file, sometimes it does become better but other times it does not.
Is there a problem with the card? or configuration methods?
I am monitoring the output on Oscilloscope and Channel-C output is not correct.
