Ok, I took some troubleshooting steps, here’s report:
00003F63: FE 59
00015F61: FF A4
First column is address in image, second is byte is from original image, and third from image received by W5100. So we have 2 corrupt bytes for 131072 bytes received. I will wait for new jack and see.
[size=150]Tony[/size], do termination resistors should have exactly 49.9 Ohm value? I was unable to find such nominal, and used 51 Ohms instead (CAY16-510J4LF). Nominal tolerance (I guess 1%)? Again, datasheet does not state anything about PHY connections, nominals and tolerance…
