How to send audio over Ethernet to STM32F429ZI board?

[chum]

My laptop act as server and my board (both the end are using statically configured IP) should receive the audio through Ethernet and store it on OTG USB drive.

I would use a plain TCP/IP connection.

Not aware of any higher-level streaming protocol implemented with LwIP.

Just keep irrelevant network traffic away, i.e. a ethernet adapter.

You will probably need some buffering scheme, to decouple ethernet reads from USB writes, and avoid stalls.

I don't understand the background. Why not storing the audio directly on the PC/laptop ?

Most projects are the other way around - the MCU streams real-time data to the PC.

I have to get real time audio through Ethernet and process it on board then revert to server(PC/laptop).

USB operation now not needed 🙂

If you have sample demo please share

Thanks in advance.

Not my area of interest, sorry.

You will surely find several Cube examples for ethernet. Not sure if Cube is a good choice for hard real-time.

The F429 discovers doesn't seem to come with an ethernet phy.
