Asahi is still in the early days of m3 support. It looks like there is zero m4 support, so I doubt you can even boot on one yet: https://asahilinux.org/docs/platform/feature-support/m4/#m4-...

I doubt it too, but I was hoping to hear from someone who'd tried it. I don't care about peripherals, even booting it without the storage with a serial getty would be useful for me.
