Currently I deal with the i210-ethernet-controller to do some timestamping from it. So, I have shorted the SDP0 and SDP1 in one piece of i210, in ptp folder, there is a file called testptp.c. The command below are what I have entered to generate the PPS from SDP1 and output it to SDP2:
# gcc testptp.c -o testptp
# ./testptp -L0,1 -i 0
# ./testptp -L1,2 -i 0
# ./testptp -p 1000000000 -i 0
# ./testptp -e 5 -i 0
and this bring me to no result have been output. After that, i type the command # ifconfig to check if the i210 can be detected, unfortunately, it is cannot be detected anymore no matter how many times i try.
The Question is how can this problem fix?
Anyone has faced it before?
Your help would be much appreciated!
