ping reply stops after some time

[peter.o.mueller at gmx.de]

Hi,

I have just finished to get our new 68332 hardware up and running (at
least partly). We use rtems (one of the latest snapshots) together with the
cs8900 driver from Chris Johns. Everythings looks fine so far.

After a fresh download (via bdm) my target replies to ping several
times, but after some time (e.g. 6 pings) there was no reply from my
target anymore. The target is still alive and I can break and debug it
using bdm. Looking on the network statistics (see below) shows that sill
ping requests (and lots of other stuff, becaus there is some network
traffic) are received, but the figures on the transmitter stand still.

I have no idea where to start debugging. My feeling is that the
transmitter task has stopped working, but I do not really know.

Can someone give me hints how to start debugging?

Thank you very much,
Peter
