Tool/software: Linux
Dear all.
I am debugging custom board which designed with AM3358 and LAN8710 through RMII interface.
It seemed to normal but, It was abnormal operaing now. I have no idea this is H/W issue or S/W issue.
i have to next step will be modified 2nd board designing. But, I can't now, because it is not certainly H/W issue.
phenomenon
1) When I tryied to 100Mbps with hub switch, it was repeated 'link is up' and 'link is down'.
2) When I connected with PC it was connected only 10Mbps only by auto-negosiation.
3) When I tested ping-test custom board with PC through 10Mbps, it was occured too much ping loss (about 30~50%).
I attched schematic, test resut. please advice for me the thing i do test more and missing point and fault point.
