when I connect Rpi3b+ to Laptop through LAN cable it works fine and I can connect so easily.
Even I find the LAN cable detected in path below and transfer the fileds easily
sys/class/net/eth0/carrier = 1
But when I connect Rpi to my hardware device its not at all detected and no LEDs are blinking.
what could be the issue?
sys/class/net/eth0/carrier = 0
the output of below command is as
ip addr show eth0
eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
link/ether b8:27:eb:31:02:c3 brd ff:ff:ff:ff:ff:ff
Please can you suggest on this NO-CARRIER and DOWN group to make a configuration from Rpi to my Hardware device.
