Hi Dan
I placed a 64-bit counter directly at the input of 10G block, and then adjusted
the accumulation length. The behavior was the same, it only works correctly
hi rolando,
what is your packet rate?
and how many bytes in each packet?
i suggest you use tcpdump or wireshark or some other packet sniffer program
to examine your packets, and see how fast they are coming in (look at the
time stamps of each packet),
and whether the data look correct...

Hi Dan
After doing what you advised me, I managed to observe the following:
When I adjust the accumulation length to 2048 everything works correctly,
then I adjust the accumulation length to 1024 and everything continues to
work fine, then I adjust the accumulation length to 512 and the PC stops
hi rolando,
it's possible that the problem you see is because your sample rate has
changed
or the valon's power output is too low for the adc.
the valon display can sometimes mislead.
i suggest you power cycle the valon, and re-program it with the settings
you want
(don't use the flash to boot
hi rolando,
are you dropping packets?
have you used tcpdump or other packet sniffer code (eg: gulp...),
to investigating what's going on when you change the integration time?
is the number of packets/second correct for the integration time you set?
if not, perhaps you accidently changed the
