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.

Hi, 

Which boot flow you are using? Is U-boot present in your flow. 

Can you please share the changes. Are you running on custom Board

Sudheer

Hi, 

I can ping all 4 port now.

But I am using 

    cd /lib/firmware

rm -f j784s4-main-r5f0_0-fw*

    ln -sf ti-ipc/j784s4/ipc_echo_test_mcu2_0_release_strip.xer5f j784s4-main-r5f0_0-fw

It will make vision_apps can't be used.

Is there any way I can use the exp eth and vision_app at the same time ?

Hi, 

KONG XIANGXU said:

Earlier issue might be due to vision apps loading ETHFW application on MCU2_0 core and wchihc enables Quad ports.

KONG XIANGXU said:

If you would like to run vision apps and use Quad ports from Linux, you need to disable ETHFW from vision apps build and rebuild the vision applications. 

Please refer to below, for disabling ETHFW from vision apps. 

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/07_00_00_11/exports/docs/vision_apps/docs/user_guide/ETHFW_DEMOS.html#ETHFW_HOWTO_DISABLE

Hi

I tried to find place as instructed 

In file vision_apps/apps/basic_demos/app_tirtos/common/app_cfg_mcu2_0.h undef this macro
#undef ENABLE_ETHFW

But can't find similar place in my SDK 

ti-processor-sdk-rtos-j784s4-evm-10_00_00_

I also tried change vision_apps/platform/j84s4/rtos/common/concerto.mak

DEFS+=ENAVKE_ETHFW  to DEFS+=DENAVKE_ETHFW

But still not work.

#include "k3-j784s4-rtos-memory-map.dtsi"

status = "disabled";  
};
&main_r5fss0_core0_shared_memory_bufpool_region {  
status = "disabled";  
};

If I add this in order to use vision app it will cause ping failure(while can ifconfig list  devices)

Is there any possible causes for this problem?

You don't need to remove the ETHFW overlay. Just disable the ETHFW build flag and rebuild vision apps.

if I used overlay ETHFW+visionapp,the ping won't work.

Here are my output of cat /proc/iomem

According this threads,"When you are using above overlay, you should not use EthFw which is mapped to MCU2_0 (main_r5f0_0) softlink with ethfw binary.
If you are using vision apps, vision binary of mcu2_0 is mapped (it also has ethfw)."

It is really possible to use ETH EXP and vision_app at the same time?

Hi,

KONG XIANGXU said:

Yes, definitely.

The only thing you need to take care of is disabling ETHFW from vision apps, as described above, as you can't CPSW from both Linux and ETHFW at the same time.


Have you tried disabling ETHFW from the Vision application and rebuilding the Vision Apps by following the Vision Apps User Guide?

Best Regards,
Sudheer

BUILD PTK2=yes
-BUILD ENABLE ETHFW?=yes
+BUILD ENABLE_ETHFW?=no

Then i run  "make vision_apps_scrub"

And update whole /usr and /opt

Hi,

KONG XIANGXU said:

Then i run  "make vision_apps_scrub"

Vision apps scrub will not build the vision apps. It will clean the full PSDK RTOS.
You need to run the command post scrub.
# make vision_apps -jN

Please refer to Vision Apps user guide for more details.

I did 1:make vision_apps_scrub

2:make sdk

I don't think problems lie here

Hi,

KONG XIANGXU said:

Post that, have you copied the updated binaries to the root (file system) of the SD card?

Can you please share the logs of the vision init script?

Is this the data flow of only use linux to control eth exp1? 

If not,can you show me the correct dataflow?

Hi,

KONG XIANGXU said:

Is this the data flow of only use linux to control eth exp1? 

No, Above is when you are using ETHFW application on MCU2_0 and virtual client on Linux.

KONG XIANGXU said:

If not,can you show me the correct dataflow?

Data flow path is direct, if you don't have CPSW2G interfaces and enabled only Quad Eth expansion eth0 corresponds to Port-1, and similarly others as well.

Please refer to Linux SDK user guide for more details about Native Linux driver and kernel options.
https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-j784s4/11_00_00_08/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/Network/CPSWng-Native-Ethernet.html#cpswng-native-ethernet

But I include k3-j784s4-evm-ethfw.dtso in my overlay ,and notice have to enable

&main_r5fss0_core0_shared_memory_queue_region {
	status = "okay";
};

&main_r5fss0_core0_shared_memory_bufpool_region {
	status = "okay";
};

to make eth exp1's ping function normally.

If not because the data flow through r5f ,what's the reason?

By the way ,I also sing the 2 original eth port in the board too.

Hi,

KONG XIANGXU said:

By the way ,I also sing the 2 original eth port in the board too.

If you are using two ports on the board, then eth1 will be the Main domain CPSW2G interface, not the Quad port interface.

As mentioned above, If you are looking to use Quad Port from Linux need to disable ETHFW from the MCU2_0 core. If you are using a vision applicaiton, you need to rebuild by disabling ETHFW and use the updated binary for MCU2_0 by copying it to root/lib/firmware//vision_apps_evm/vx_app_rtos_linux_mcu2_0.out

If you are using a vision applicaiton, you need to rebuild by disabling ETHFW and use the updated binary for MCU2_0 by copying it to root/lib/firmware//vision_apps_evm/vx_app_rtos_linux_mcu2_0.out 

Yes,I followed your advice and I can use vision_app and Quad Port at same time now.

But I have to change

&main_r5fss0_core0_shared_memory_queue_region {
	status = "okay";
};

&main_r5fss0_core0_shared_memory_bufpool_region {
	status = "okay";
};

in k3-j784s4-vision-apps.dtso to enbale the ping for Quad Port.

If I don't enable this r5f memory ping for Quad Port won't connect but without any error logs.

I want to know why this happened, after all it's said "r5f memory"  ,why it affects the ping function in linux?

remove "main_r5fss0_core0_shared_memory_queue_region" from vision apps dtso and don't use the ETHFW overlay.

Also ,why 

Doredla Sudheer Kumar said:

disable "main_r5fss0_core0_shared_memory_queue_region" as these are part of the "main_r5fss0_core0" node.

would affect my linux 's ping .It doesn't make sense if eth don't rely on rtos.

You are not interested to have this node, so I suggested to remove it.

Can you please share your device tree tops check overlay failed issue. Also, are you using SD boot mode or not?

RTOS vision Apps memory map has these sections in linker file. 

I am expecting it should work when you remove the node and managed dependency in device tree properly.
