TDA4VM: Two questions about TCP/IP

Linda Wang

Part Number: TDA4VM

Hi engneers of TI,

There are two questions about TCP/IP:

1.TDA4 is in ESTABLISHED，then Tester send an error ack TCP packege, we expected to accept an ack from TDA4, but TDA4 didn't respond.

2.Tester send an error length UDP packege, we expected TDA4 to drop this packege, but TDA4 accept this length error UDP packege.

It is different from TC8 , so, I wonder how TDA4 work for those issues.

Linda,

Which port are your testing? Is it the CPSW2G or Virtual MAC?

Hi, Jian

We use cpsw9g, actually, the TCP/IP test is a test for the ipv4 protocal, which is in TI linux code: board-support\linux-5.4.74+gitAUTOINC+9574bba32a-g9574bba32a\net\ipv4, we want to know how the protacal work for these issues.
