Hi everybody,

I am working in a project where I have to time stamp incoming frames from an Ethernet network and store them in the SD Card.

I have observed that after a random number of frames (1, 71, 235, 177000) the Ethernet module freezes and no further frame is recieved. No Interrupt is generated, and the Ethernet module does not modify any descriptor after this.

The traffic we are monitoring is periodic traffic, with 1 ms between frames at least.

Is this a limitation of the Ethernet module?

Does anybody experienced something similar?

Regards,

José Miguel.
