I have 2 BBB, following is the setting:
I connect as BBB - eth0(RJ45) - PLC - PowerLine - PLC - eth0(RJ45) - BBB
This method I can work fine on Beaglebone(White), but BBB cant work.(Only changed board)
Does anyone has idea? Thanks.
Run tcpdump on the network interface, check that the ICMP packet is actually getting out through the interface, and similarly check what does tcpdump see on the receiving system.
there is nothing shown on terminals.
tcpdump -v icmp
tcpdump -i eth0
ping BBB1’s IP
When I ping each other, both show “Destination Host Unreachable”
