X-CUBE-AUDIO-KIT: LiveTune Designer communication firmware?

[Rodo]

Hi all,

I'm trying to use Livetune to make an mp3 player but it only works once connected to a board. I have a custom Nucleo-U5A9 (originally a Nucleo-U575, I replaced the MCU and added xtal). 

I'm reading UM3297 Getting started with X-CUBE-AUDIO-KIT and on page 6 (picture below) says:

"The connection is successful only if the firmware running on the device includes the Designer communication firmware."

I would like to include this "Designer communication firmware" into my custom board/firmware but I can't seem to find any reference to it anywhere. I'm pretty sure is part of the examples firmware but I rather not hunt for it that way unless there is an example for the U5A9 which I don't see. Even so ... this "Designer communication firmware" doesn't seem to be designated as such in the example projects.

where is this "Designer communication firmware"? How do I integrate it into my custom U5A9 board?

Any help is appreciated... thanks.

Hi @Rodo 

Did you take a look at the readme, Step 1: Flashing Firmware binary. For source code, you can find it under x-cube-audio-kit\Projects\STM32H573I-DK\Applications\Livetune. Unfortunately, STM32U5 is not supported on this package but should be easily ported from H5 examples.
