Hi
We have the tcp/ip stack up and running by default on our ui board that uses the imx8mn.
We put the board to sleep using the following command:
echo "s2idle" > /sys/power/mem_sleep
echo mem > /sys/power/state
After we have issued the command we have monitored using wireshark the the router send an ARP message to the ui board. But the ui board does not respond to the arp message.
From the above the router sends ARP message to the ui board for at over 10 minutes. Eventually the router removes the ui board from it attached devices.
Hence if we ping the ui board it is un-reachable.
So is their a way to keep the ip stack alive when the imx8mn is asleep?
