Linux is quite slow on every Risc-V board. Probably only fast-ish I’m aware of is Milk-V Pioneer.

Buy an used Thinkpad for 50-100 bucks and install FreeBSD there. VM works too, but something is always missing.

Expect to read much more documentation than with Linux and it is a good thing.

Will Framework community start writing their own kernel+OS for this board?

Everything related to Bill Gates is dogshit.

TSMC is for bleeding edge chip. 10nm and above are produced everywhere. Mostly 28nm, since it is the cheapest. It won’t be easy to build 5nm fabs but I bet still doable.

Isn’t thwre a single one RISC-V capable production line in the US? Imagine if Apple starts their own chip production.

That’s a rule with everything you auction at Ebay.

Thanks but no thanks.
