At least for desktops and laptops.
For servers I’m still primarily running Debian (and one instance I’m running Arch).
The reason why I settled on Arch is primarily because the combination of bleeding edge and being stable enough for daily driving it. The AUR also adds sooo much, that there is nothing I really don’t need to manually install anymore.
For servers, I basically want a rock stable system. Hence why I’ve chosen Debian Stable.
Yes you can, it won’t be great though.
I used to maintain a Linux distribution called “OpenWM8650” (back in 2011 / 2012) which was specially aimed at the WM8650 and WM8505. It would run off the SD card. Which wasn’t great, but the flash onboard support was horrible at best.
Maybe you can find some old information on it, on XDA because the website for the initial distribution is long gone.
