Hi champs,
My customer is facing the Ethernet PHY DP83822IRHBR connection problem, the PHY1 works well but PHY0 fails to work. He conducts the PHY SWAP experiment and makes sure the connection problem follows PCB, because F28388D is BGA package so it is difficult to do DSP SWAP test.
According to my customer, there has no TX clock signal to PHY0. He wants to know what signals he needs to check to solve this problem, makes sure PHY0 works without problem.
Please refer to below reset and TX clock waveforms of NG and OK units.
** PHY reset signal (left side is NG unit and right side is OK unit).
** TX clock waveform (left side is NG unit and right side is OK unit)
Please advise how to debug this problem, thank you.
Regards,
Luke
