HI,
now,i still have 2 problem from the closed thread "https://e2e.ti.com/support/interface/f/138/p/832964/3097904#3097904":
1.the host can transmitte data packets correctly. afer pass the PHY,the short packets transmission (200 bytes) is no problem,but when transmitting long packets(1400bytes),issues occur. for example ,1400bytes,the front packet bytes is correct ,but the last packet bytes loss all .
by the way,normal 64 bytes ping,it's no problem. when ping 1400 bytes,data loss very Seriously.
2.In normal operation mode ,soft-reset can work correctly. When MII loopback , after soft-reset ,the PHY can not link normally. additionally,the same cords and the same configuration can work normally on Xilinx DEMO board.
please help me analyse the cause,thanks very much!
