Is LPDDR required for sw_usb_audio on a custom XU316 board?

Post by gunesgrkn »

Hello,

I am using the XK-EVK-XU316 board and I have successfully run the sw_usb_audio example on it. Now I would like to design my own custom board.

While checking the datasheet, I noticed that the board includes LPDDR memory. Do I need to include this memory when designing my custom board? Is LPDDR required for running the sw_usb_audio example?

Additionally, what is the purpose of the LPDDR on the XK-EVK-XU316 board?

Thanks.

No it's not used by the USB Audio code base.

It could be used for lots of things, big buffers, reverb, camera frames, ai models, etc.
