Hi:
I have a custom AM5708 based board and SDK6.02. I have an ethernet board with 2 interfaces (eth1 and eth2) over PRU_2.
My phyter is DP83822. The issue is that when I down either interface ("ifconfig eth1 down" or "ifconfig eth2 down") I get a crash
(see attached file) when unplugging and plugging the cable back.
It seems that the crash occurs because there is a phyter interrupt that is not attended. It is supposed that in
down state the interface interrupts, included phyter´s, should be disabled.
If I configure in the dtb the phyter no to generate interrupts the crash does not happen but I see that after some unpluggings/pluggins
the interface still receives frames but does not send any. In principle this should not have to do with the phyter interrupts.
Regards
Billa
