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.

I did. Your answer is pretty much what tech support told me. Somehow you guys think that porting code from your examples to another project is relatively easy. I find it to be the opposite of easy. I pretty much gave up on Livetune at this point. I'll dabble on it later. If I may suggest ... make this "x-cube-audio-kit" part of cubemx under "Middleware and software packs". Once enable you can show which version to include (designer, tune or release). There that's my two cent suggestion.

Thanks for the reply though.
