Hi, we found a strange thing in Davinci EVM board.
if we ping the board with 32 bytes or 24000 bytes data, everything is OK.
But if we ping it with 4000 bytes, the time is changed randomly.
the following is the printing:
ping 192.168.2.199 -t -l 4000
Pinging 192.168.2.199 with 4000 bytes of data:

I checked with my friends. They are using DM365 in their products. All have the same problem.
This would cause serious delay in video data transferring.
We are using kernel Linux version 2.6.18_pro500-davinci_IPNC_DM368_2.0.0
Any suggestion?
Thanks very much
