Hi,

I'm currently working on LPC54628 board for my ethernt interface. In this my issue is during the configuration i'm unable to declare TDES3 register or OWN bit in keilv5. how to enable the own bit in the program. And other issue is during the transmission i'm only getting the ARP request can't able get the ARP response is there any particular method for this. Kindly help me out of this.

Thank you!

Hello saidevaraj m,

TDES3 is not a register, it is part of Transmitter descriptor:

In SDK driver, you can find the definition from:

About other question, I recommend you first have a look at the ethernet demo under SDK.

Have a great day,
