ADIN1200 EtherCAT issue

Hi Dimitrov,

Would you be able to provide a register dump from registers 0x00 to 0x1F for both of the devices to help point in the direction of the problem achieving a link? You can share these files through PM if  you like.

The Link Status / PHY_CFG1 pin does not appear to have and external strapping resistors, can you confirm this? The PHY_CFG1 pin does not have any internal pull downs so it must have external strapping resistors.

Resistors R3, 4, 39 and 40 are marked as DNP on the schematic, can you confirm these are not on place on the board.

Regards,

Mark

Exactly, remove all DNI, then add a 10k pull-down resistor for PHY_CFG1.
I did so and it worked.

Hello Mark, 

Thank you for your answer!
I added the pulldown resistors, but there is no improvement so far.

You can find the register dump in the table below. Both PHYs (0 and 1) have the same configuration.

I'll double check the DNI resistors a little bit later.

Best regards,

Dimitrov

You should compare your schematic and INFINEON's schematic, then do not add DNI Components.
Check ECAT.PO.LINK, it should be at pin C of BCR108.

Note. You need to add 10k pull-down resistors in both ADIN1200 at pin PHY_CFG1.

Additionally, you don't need to change any source code. It will work fine
