You can=C2=A0get an idea of them all from the layer index's list of machines which is showing 22 pages of them!=20 https://layers.openembedded.org/layerindex/branch/master/machines/?q=3D&bro= wse=3D1 Some have better support than others, we've had the Beagle devices like the BeaglePlay and earlier devices like the BeagleBone and BeagleBoard supported as one of our test platforms for a long time.=C2=A0That has basic support in meta-yocto with beaglebone-yocto and a full BSP from TI as well. There are others like the various RaspberryPis and may more, including more experimental ones with RISC-V processors. It sounds like the audio output might be important to you and however you plan to interface the buttons to the system so that may be something to factor in. You might need USB? That might narrow down your choice. I'd probably try and find a board which holds interest to you as well. Cheers, Richard
