Tool/software: TI-RTOS
Hi there,
I'm using AM5728 IDK, SDK version is 5.03.
and testing NIMU_BasicExample_idkAM572x_armExampleproject
When I ping the board with packet size of 1472 bytes I get a good response.
$ ping 192.168.1.4 -s 1472 -c 1
PING 192.168.1.4 (192.168.1.4) 1472(1500) bytes of data.

When trying packet size > 1472 I don't see anything coming back from RTOS.

According to tcpdump output the large packet is fragmented and sent over two frames, but RTOS doesn't seem to respond.
Any suggestions?
Thanks,
Nir.
