TDA4VM: TDA4 driver eth switch use cpsw2g

Yao Zhang

Part Number: TDA4VM

hi expert

We use tda4 in QNX system, and we want to use cpsw2g interface to drive an Ethernet switch chip

Then use io-pkt-v6-hc -d cpsw2g to access the device in QNX system。

My problem is ，If I want to use io-pkt-v6-hc -d cpsw2g access the switch chip, should the driver of the switch chip run on mcu2-0?

Should I develop the driver of the Ethernet switch chip under the PDK path in the RTOS folder of the SDK，just like adding a PHY driver

Hi,

I did not get your question.

CPSW 2G driver is already implemented in QNX.See this page

By Ethernet switch chip, do you mean a PHY ?

hi vineet

What I want to confirm is whether the switch chip instead of the PHY chip driven by cpsw2g will affect the protocol

in the next link i found CPSW9G is not support Multicast broadcast

TDA4VM: Does TDA4VM CPSW9G Multicast supported in SDK 7.3? - Processors forum - Processors - TI E2E support forums

and we test the CPSW2G is support

So we want to use a switch to replace PHY, and still use cpsw2g to drive, to make up for the incomplete protocol

Hi,

So you want to connect CPSW 2G directly to another ethernet switch ? That's called a MAC 2 MAC connection.

Yes it's possible. You will have to make some changes in the driver to disable PHY initialization.

Well, right now multiple cores cannot receive multicast frames. But that support is coming in SDK 8.1.
