Awesome project! But please compress your images, it took me 2 minutes to load your website. Convert everything to <300kb progressive jpg and use svg for graphics.
OK.
"Open source" with nvidia hardware? Good luck with that
nvdla is actually open source including (most?) of the low level software: https://github.com/nvdla

Looks like their Hard IP is proprietary but based on open high-level designs such as Rocket and BOOM. The peripherals situation is mixed, but they've stated in the past that they're quite OK with using open designs whenever feasible.
The high-level design is proprietary too. As I said elsewhere, SiFive CPUs are just as closed as Arm ones, you just pay a royalty to SiFive instead of Arm.
They have source code files for their 'Freedom' core designs up on GitHub under an Apache 2.x license. These can be directly used to evaluate their designs as FPGA soft-cores.
I would love a RISC-V board to play with that is a bit more stable and about the size of a Raspberry Pi within a reasonable price range. The SiFive development boards are pretty pricey, definitely showcase hardware (look at all these peripherals or this is basically a desktop computer!).
I'm hoping with the explicit call out of open hardware and open software that this board won't have the same issues as the Beaglebone Black...

I think in the real world "No percentage of each sale payments to ARM" is what will drive RISC-V. An "open" ISA doesn't force anything else to be open. So, use cases like Western Digital, where they can quit paying ARM a percentage of every hard drive they sell, for example. As for technical advantages, each RISCV vendor has their own choice of how to implement, so it's hard to say anything broad that applies to all…
> quit paying ARM a percentage The percentage is very small, though. So this argument only works for very high volume use cases, which is why the RISC-V eval boards are currently far more expensive than comparable ARMs. Do WD do their own silicon yet, or do they just buy the parts?
WD said they were finishing taping out their first production design about a year and a half ago, so I assume they have started shipping them at this point, but it's hard to find info.
The website is super slow. It downloads 7.66MB of files, and it took 1.05min to load for me on a 2020 MBP with 150Mbps bandwidth and ~15ms latency.
Is there something inherently complicated in adding a SATA/M.2 port to board like this? The RaspberryPi is also "disk-less", which to me is one of the major limitations. It's a super interesting little board, and I love that it's a RISC-V, that could really help getting the CPU in the hands of people. I just don't know enough about these things to understand why there are no storage connectors (other than an SD card…
Why would you need SATA when you have SD, also USB3 and Gigabit Ethernet? I have no problem booting from the SD then accessing data on my SATA drives using a USB-attached controller, also plan to get a NAS. Sure, it would be great to have connectors for everything and support for every cool standard but these guys have to give up all what is non-essential to keep it small, cheap and possible to engineer by a small te…
There's no reason you couldn't kick SD transfer speeds up towards SSD speeds other than the protocol doesn't allow for it.
