First question asked Welcome!

On the EtherCAT PHY dev board there is a pull-up resistor on RXD0 of the second PHY (R232)
Anyone knows why it is needed, and also why it is not on the first PHY?

 

I forgot to place on my custom board an we wonder if this is a big problem, because it all seems to work fine...

 

Thank you,

Hi @JeroenVDZ,

Could you specify which XMC EtherCAT kit are you referring to?

Regards,
Nikhil
