Has there been much traction in building RISC-V application processors? Something like a RISC-V Raspberry Pi style SBC would be interesting to see, but the only thing like that I am aware of was enormously expensive (the HiFive Unleashed @ $999). I think the semi-open, high-volume, competitive ARM SoC market is going to make it very hard for RISC-V to find a niche in higher performing devices.

how about https://www.seeedstudio.com/Sipeed-Maix-Cube-p-4553.html ?

RISC-V Dual-Core 64-bit, with FPU and some 'machine learning' accelerator

or cheaper https://www.seeedstudio.com/Sipeed-Longan-Nano-RISC-V-GD32VF...

Those are both microcontroller-class RISC-V processors (of which there are many), not something capable of running Linux.

I get your point.

You still can get linux on the K210 https://www.cnx-software.com/2020/02/17/how-to-build-run-lin...

and it seems it's mainlined now: https://www.phoronix.com/scan.php?page=news_item&px=RISC-V-C...

Does this work? https://conferences.computer.org/isca/pdfs/ISCA2020-4QlDegUf... “Xuantie-910: A Commercial Multi-core 12-stage Pipeline Out-of-order 64-bit High Performance RISC-V Processor with Vector Extension,” Alibaba

I hope so. I also hope someone will reinvent mass-market for Power/PowerPC architecture.

It's good to have a choice
