Hello,


I am trying to configure Ethernet on a tc399. I used the Demo Illd as a guide, and it almost works. For testing i use a Vector Can/eth interface connected with an RJ-45.
If i send a messege from Canalizer via eth, the controler receive it, but if i try too send from the controler nothing happens. The setup works because i tested on a tc299.
Anyone had this problem? Any sugestions?
Also in the datasheet it says too make a Transmit Poll Demand, wich tc399 dosn't have like tc299.


Thank you!

Kind regards.

iLLD example for TC3xx configures the PHY as loop back mode, so no frames get out, to fix this disable loopback mode and comment
portions of the code that is waiting for the received frame (demo expects to receive the tx frame)

Yes, but i removed the portion off the code that waits for frame, and disabled loopback mode. As i am tring too find out DescriptorTailPointer gets the rigth adress, and it should work
