@akif-durmaz Hi ，what i mean is you can try to use another ethernet connector.

@liamski Hi, if your prototype used the Omega2S+ or Omega2+ Module? And is there any circuit change around the Omega2S+?

expansion header is 2.54MM~

@FredyAlvarez Hi ,you can use 115200 Bauds. and if the Omega2 runs ok, the serial log will show something.

@akif-durmaz
Hi, i had checked the Normal ethernet connector（RJ45），it seems that the inside schematic isn't as the same as yours. Here the connector's sch has the same channel coil of RX/TX.SPEC of HR913550A

@akif-durmaz Hi ,please add a screenshot of the ethernet connector and transformer 's schematic.

The lastest Omega2S reference schematic had deleted the R401~R406，C403 and C404.

@akif-durmaz Hi ,For the Omega2S reference schematic ,there are two options for the ethernet connection,option1 is using ethernet transformer ,option2 is a simpler circuit which using resistor and capacitor to instead the transformer . and each of the option can work.
I had checked your ethernet port circuitry screenshot, there are some connection is not right, you can't connect the omega2S's ethernet signal line to the ethernet port.
