Don’t know where exactly, dp83848 datasheet manual re-flowing made it work. A resistor in the range of 1 – 5 kOhms dp83848 datasheet be sufficient. Can they cause such a link problem despite the well-working link LED? Jun 19, TI and its respective suppliers and providers of content make no representations about the suitability of these materials for any purpose and disclaim all warranties dztasheet conditions with respect to these materials.
Sep 12, 1: If you have further questions dp83848 datasheet to this thread, you may click “Ask a related question” below. Can someone double check my schematic to make sure I didn’t screw dp83848 datasheet up here?
I have tried to debug the connection to DP to no avail, and will definitely appreciate any input. Ethernet Cable Plugged in at Start Up: Oct 22, 8: Jul 5, 4: Patrick, can you verify this dp83848 datasheet
I see you know a lot about the Sep 12, 9: As mentioned by Aking Jin, I tried his approach of setting forced 10mbps, and the LED on dp83848 datasheet computer light up, and dp83848 datasheet link led stays good on my phy as well. When I try auto negotiation this scenario explained on the above post occurs.
We are glad that we were able to resolve this issue, and will now proceed to close this thread. Typical Dp83848 datasheet Diagram Good thing is that if you’ve missed the magnetics, you can probably find the same pinout connector dp83848 datasheet would have the magnetics internally.
I had an issue with the connector when I’ve used a wrong connector with magnetics, that supported voltage output from PHY instead of required current dp83848 datasheet. Jun 19, 1: Post the RJ45 connector datasheet.
In my board, the PHYAD pin 42 was dp83848 datasheet floating but probing this pin shows 0v instead of being pulled high. Also check DP datasheet section 1. I was suspecting this only occurs dp83848 datasheet the LED LINK light is good which for me, as mentioned above, only hapens one sec and it goes off and repeat the cycle. Here are the values that I’ve read from the DP registers.
DP No Link – Page 1
I expect this behavior for startup, but this also happens even after software configuration, which seems weird to me. In reply to Tamas Novak:. Sep 12, 5: Content on this site may contain or be subject to specific guidelines or limitations on use.
After power up, with no software interaction, default straps other than dp83848 datasheet you have already identifiedand no connection to the RJ, the device should dp83848 datasheet configured for Auto-Negotiation with no link and no activity. Otherwise, you can use really short wires between PCB and dp83848 datasheet connector to test it if the pinout doesn’t match.
Glad to hear that your problem is resolved. There are two measurements dp83848 datasheet I would recommend:. I checked MDIO on scope: Don’t care red circles.
