Hi,Jack
I realized a firmware that acquire data using ADC_MKID_4X yellow block and
then pack the data into multi 64bits data to 10Gb yellow block in ROACH2.The PC
receiver UDP package through 10Gb cable.The ADC_MKID_4x board clock is
512MHz,and the ROACH2 worked on 128MHz. I use part of Tuto
Traffic from the ROACH doesn't go through the PowerPC, so my guess would be
that it's unlikely anything is causing issues there. I'm not actually sure
how you change PPC settings which aren't set via the "start_tap" command.
For >8kB packets, you should check any options to increase the TX buffer

Hi
Thank you Jack.
I didn't see tx overflow indicate and I connect the 10Gb tx_overflow port to
led2 of ROACH2. In different seeting,I found when there is a overflow and I can
not received any package.In my firmware, I also select the option of 'Enable
Large TX Frames(8k+512).So, I am sure
Hi. Since you can receive 1500 packets error-free, it seems like your PC
is getting more data than it can handle and starts losing packets.As
Jack says, the PPC doesn't get involved in it at all.
Using small packets like you are using makes for more work on the PC side,
as many more interrupt
Thanks for you help. I will try that as your suggestion.
Cheers!
