Hello,
I am trying to port lwIP to a EFM32 platform and my driver is doing
something that I cannot understand.
In the beginning it replies nicely, but after a while it stops replying for
some time and after that it goes into a reply mode when it bulks all the PING
replies one after the other without doing anything else. After a while it bulks
the ARP respons saying that the IP is at MAC address xxx and after that goes
into a reply late mode when it replies after each request, but it has some
differences in the number of the request reply(i.e. Request seq 3870 followed by
reply seq 3863; request seq 3871 followed by reply seq 3864) after that the PC
starts sending ARP requests and the chip sends all the remaining PING replies
and after that it dies.
Can you help me understand why that is happening?
I tried to look into the stats and I couldn't see any errors or
problems.
Thank you in advance,
KS
