Hi there.

 

I have my project working successfully on Netduino plus kit 

I built my own PCB based on Netduino Plus schematics with exception of Magjack RJ45 which has built in transformer same as HX1198NL used in Netduino plus .

 

 

The problem I have is that I am getting an error Link between Magjack RJ45 and DM9161 - same setup and code works happily  with  Netduino plus kit 

 

I will be most grateful if someone can assist me

Hi Nissim, As long as your Magjack has the same magnet orientation and internal component selection as on Netduino Plus 2, it should "just work." That said...you will need to make sure you make your traces the right size and length and all of that fun stuff Just to confirm--you're able to initialize networking using the DM9161 but the physical link between it and the MagJack is what is failing? Also--are you using the same DM9161? There are a few options out there. Chris

Thank you for your reply Chris

 

Following your advice, I noticed that the orientation of transformer on Magjack does not match exactly as on HX1198NL IC .  Could this cause the problem I have?

 

The DM9161 initialising because I get correct  register status.

 

The LEDs on my board seem to behave same as on kit I have

 

Thank again for your good on going  support
