PING fails for larger packets of size 2500 bytes
Im running the helloWorld example availble in the MCSDK 2.0 for the Advantech EVM c6670.
The IP assigned is 192.168.2.100.
I try to ping the Ethernet of the DSP c6670 EVM by giving the command as ping 192.168.2.100 -t and all works fine as i get the Ping replies as shown in the attached images.
I try to ping the Ethernet of the DSP c6670 EVM by giving the command as ping 192.168.2.100 -t -l 2500 , <which means by sending 2500 bytes of ICMP
packets>, and on observation i see that some ping replies are received and some are failed, due to IP refragmentation.
Kindly let me know as to how can i resolve this issue and if any settings need to be made in the code.
I'm able to ping successfully on different hardware (OMAPL138).
Which example are you using for this test?
Can you try using the standard helloWorld NDK example?
Im using the helloWorld example found under :
C:\Program Files\Texas Instruments\mcsdk_2_00_00_11\examples\ndk\helloWorld
This was obtained after installing the MCSDK 2.0.11 version. This is the standard helloWorld application shipped with MCSDK examples.
Im running the test on Advantech EVM c6670.
Can you please try the same on this platform as well ? It would be great, or any of you there who have access to this platform.
Sorry for the delay. Let me try this. in the mean time, can you verify that the PC is not fragmenting the packet.

Did you verify that the packet is not fragmented?
Well Arun, the Packets are fragmented and sent across the wire.
I demonstrated the same test on a different laptop and it worked properly, seems there was some problem with the laptop that i was testing the ping test.
Thanks... im facing another issue with NIMU driver of packets getting missed at the application layer. The issue is raised at
Pls help me with that issue too.
