TDA4VM: Setup the communication between PC and TDA4x using ethernet

Seetharama Raju

Part Number: TDA4VM
Dear experts,
I'm working on SDK 08.02.00.05. I want to use ethernet to transfer the data between pc and TDA4Vm and vice-versa. I have gone through couple of E2E threads, which are useful for my requirement.
https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1344742/tda4vm-how-to-transfer-data-between-pc-and-tda4vm-board-through-ethernet?tisearch=e2e-sitesearch&keymatch=harib#
In the above thread, it is said like this. "If you want to transfer custom data from PC to CPSW, you have to develop/write an application to transfer the data via Network interface and connect the PC to CPSW and run application from PC."
I have gone through the documentation available at
1) $RTOS/pdk_jacinto_08_02_00_21/docs/userguide/jacinto/modules/enet.html.
2)$RTOS/ethfw
Please clarify me which one is useful for my requirement.
Could you please help me how to use the API's to enable the communication between PC and the board.
I have shown the requirement in the below image.
Note: I have gone through and understood the basic UDP socket based server-client communication from the reference:  www.geeksforgeeks.org/.../
Thanks,
Seetharama Raju.

Hi,

As your requirement will be input from PC and output to PC.
Is input from and output to same PC? If yes, why you need to transfer to TI device in between?

If both input and output are different PCs then you need more than one Physical port. Which means you need to use CPSW9G.

For CPSW9G use EthFw to enable multiple CPSW ports. Enet will enable only one of CPSW Port.

Sudheer

My requirement is this:

Suppose File based segmentation app, where we feed the input images from the sd card and process the app and get the output images and visual display on Display monitor(edp/HDMI).I want to feed large custom input data( cannot give from sd card due to memory limitation) from pc to the application(server). The application(TDA4x) process the data and give the visual display and output images. So I want to use ethernet to feed to input images and get the output images.Is one pc not sufficient for this purpose?

Please guide me based on this.

Thanks,

Raju.

Yes, One PC is sufficient for this Use-case.

You have to implement application on PC side as reading file data and frame Ethernet packets and send from PC to TDA4x CPSW Port.
TDA4x side extract the ethernet data and send to display module.

Thanks for the confirmation.

Is there any demo app in SDK that is using ethernet firmware similar to my use-case?

Thanks,

Raju.

No. We have independent Ethernet application for Tx & Rx realization.

Please refer to Enet loopback example (Tx & Rx the same packet) or enet lwip example (Iperf, ping test with remote PC)
Refer to PDK User Guide for more details.
Code for above applications will be available from "RTOS SDK/pdk/packages/ti/drv/enet/examples/"

Sudheer
