TDA4VH-Q1: How to use Quad Port Ethernet Expansion Board with J784S4XG01EVM BOARD

Hi,

Would you like to have a native Linux driver for the CPSW9G or ETHFW model application?

By default, the ETHFW application runs on the MCU2_0 core. In this case, Linux has a client driver with virtual network interfaces as a virtual switch and a virtual MAC-only interface.
Please refer to the ETHFW User Guide for more details.
https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j784s4/latest/exports/docs/ethfw/docs/user_guide/ethfw_c_ug_top.html#ethfw_j784s4_port_cfg

If you would like to run a Native Linux driver, please refer to the FAQ to enable the Native Linux driver for CPSW9G.
[FAQ] How do I bring/brought up Ethernet interfaces for Main Domain CPSWnG in Linux from SDK Version 9.0 and above?

Hi,

I copy the whole k3-j784s4-evm-quad-port-eth-exp1.dtso and paste it under k3-j784s4-evm.dts.

But my booting stucks at

I only want to use ENET EXP 1 in linux.

Can you give me some possible reasons for this?

Hi,

this looks like a problem I had with SDK 10 a while back, too.

You could have a look at this thread:

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1425786/j784s4xevm-using-j721exenetxpanevm-with-psdk-linux/5566357#5566357

From what I remember, the .dtbo for the expansion board was broken on 10.0 because it wasn't updated to reflect other changes in the device tree. I posted a patched .dtbo with a workaround that worked for me in that thread. Maybe you want to give that a try.

In that thread Sudheer indicated that a fix should be included in SDK 11. Maybe you could give that a try, or check with Sudheer if it was actually fixed.

Regards,

Dominic

Hi,

Thank you for your kind help!

I tried change the uEnv.txt to name_overlays=ti/k3-j784s4-evm-quad-port-eth-exp1.dtbo

It seems get more longer log relate to net,but still can't boot.
