Linux capable RISC-V boards do exist but cost several hundred dollars or more with the likes of HiFive Unleashed and PolarFire SoC Icicle development kit. If only there was a RISC-V board similar to the Raspberry Pi board and with a similar price point… The good news is that the RISC-V International Open Source (RIOS) Laboratory is collaborating with Imagination technologies to bring PicoRio RISC-V SBC to market at a price point similar to Raspberry Pi.
I’m 100% ready for fully top-to-bottom open source hardware, whether it’s Power9/Power10 at the high end, or RISV-V at the low end. ARM is a step backwards in this regard compared to x86, and while I doubt RISC-V or Power will magically displace either of those two, the surge in interest in ARM for more general purpose computing at least opens the door just a tiny little bit.
From the second link:
“””PicoRio aims to be open-source hardware as much as possible, with the CPU part being fully open, but the memory PHY, USB 3.0 PHY, GPU, and other I/Os will still be closed source, even though the goal is to eventually have as much IP released under a BSD-like open source license.”””
Even accepting the SoC will be effectively closed source (nobody will be able to create a clone without licencing the GPU hardware), Imagination Technologies doesn’t have a good track record for Linux driver support for their GPUs.
If the software (because of the graphics drivers) is even more proprietary that the Raspberry’s, what’s the point other than having a toy for playing with the RISC-V architecture?
