#12Earlier quoted context omitted.
The Hazard 3 is basically a hobby project of Luke Wren, a Raspberry Pi Employee. He's contiuing to evolve it further, but I don't think it's ready for a full replacement of the Cortex-M yet, especially in regards to the Security Features. The source code is all from Luke Wren and I don't think other cores use the source code directly, but improvements to test harnesses or general implementation patterns as well as be…
The Hazard3 in the Pico 2 are bigger, more capable cores than the Cortex-M0 in the first Pico, and therefore in general faster at the same clock for compiled code. You're supposed to be able to just recompile most Pico projects to use them as long as there is no ARM assembly in it. They are only inferior to the ARM Cortex-M33 cores in the Pico 2.
So they come inferior in the only place it matters, gotcha

#13I don't even know what would be the point of such device, and if there really is a market for it for tech companies. I would say yes? As a consumer, all I want if a very minimal "phone", with wifi, touch screen, battery, but no 4g or mobile networking, and linux on it. Just the cheapest, smallest, wifi, battery-powered, touchscreen LCD device that could exist that can run executables. People are going to say "but jus…
They don’t make cellphones, they make little computers. Hypothetically you could probably use an Arduino or an esp32 to make a cellphone, but you wouldn’t say those organizations lack an all-integrated consumer device, right? They just aren’t in that business.

What about Commodore where it took 7 hrs to boot (video YT)
Edit: oh damn this one is even worse 8.4 days ha

#15It would probably make more sense to target something like this https://www.hackster.io/news/andrew-bunnie-huang-prepares-th... with linux, has MMU and more RAM.
Availability is a major factor in projects like this.

#16I'd really like to see a pi zero 3 that runs on RISC-V, it might be the kick in the pants RISC-V needs to go "mainstream" at least in the public view. People know raspberry pi, nobody outside the RISC-V scene really cares or even knows about MILK-V

You can buy touchscreen enclosures for the various pi models. If you want to put in the effort to make your own PCB you could really slim it down by using a pi compute module

#18I wish I could buy RP2350 with the ARM cores being hard-fused disabled, "cheaper" since no ARM royalties would have to be paid. That said, I wonder how much they did improve their hazard3 design, because we all know the future is no PI locked ARM cores. I wonder if they are sharing part of the design of other open source RISC-V cores. If those efforts are kept significant, the future is looking good and better there.…

Better yet, put 4 RISC-V cores on there!

That is too practical. For ultimate HN bait it needs to include Rust deployed (over QUIC) as WASM on RISC-V.

But the CPU needs to be build in Minecraft.
