Using NETCP communication between ARM and DSP

Hi STefano,

Why do you want to use ethernet communication between ARM and DSP instead of IPC? Also I recommend you to use latest MCSDK 3.1.4.7 for your development. Please find the download and user guide link below my signature.

Thank you.

Dear STefano,
I hope, you can try to use the NETCP module in DSP code through IPC mechanism.
You have to run the Linux on ARM core and run the NETCP DSP code on DSP core then try communicate with IPC between ARM & DSP.

Please refer to the following links.

Hello,

thank you for the replies and interesting material provided.

Anyhow my need was different, I try to reformulate the question.

I would like to establish a data path between DSP and ARM, not a control path, so I would like to use NETCP as IPC and not queue based one.

In particular, I can successfully establish a data path between DSP and a simple application running on an external PC, through standard socket, but if I move the same application on ARM, it seems that packets cannot be routed properly to ARM.

Any suggestion?

Thanks
Regards
Stefano
