The Foundation's charitable objective is education, so sure, it's not necessary, but there really seems to be no reason for it to be closed - I suppose it's just 'closed by default'?
I honestly didn't realise the Raspberry Pi isn't open source. Why isn't it? The Foundation's charitable objective is education, so sure, it's not necessary , but there really seems to be no reason for it to be closed - I suppose it's just 'closed by default'?

Promising hardware, though this isn't looking like comparable hardware even to the Raspberry Pi Zero. Only has a quad-core 64-bit RISC-V (RV64GC) processor at 500+ MHz. RAM size not specified. If it was priced in the $5-15 range it would be more or less practical, but higher than that I'd be buying it solely for the architecture novelty.

I believe it's because the Broadcom System-on-a-Chip (SOC) that the Raspberry Pi uses has one or more binary BLOBS that are required to access features on the SOC. RISC-V is an open standard; chips made based on this standard are open source.
One of the comments I made to myself was that on the die shots, USB3 part is as big as a CPU core ! What would need so much silicon ? Isn't USB3 hardware more or less a serial bus? Is it logic or memory or analog interface parts here? I am curious.
Why is RISC-V even so hyped up/successful? Other open ISAs precede it, and AFAIK the code density that RISC-V allows is disappointing considering the designers had an opportunity to start from scratch.

A board competitive with the Raspberry Pi 1B (800 MHz single core) is not "incomparable."
