So I've had the itch to get a 64-bit RISC-V board of some sort. For reasons I won't get into, I'm not so interested in the 32-bit version.
The prices for the Genesys 2 Kintex-7 are $1000 USD at Digikey, which is way too much to spend on a hobby. I suppose I could try to port the FPGA code to a cheaper platform, but I'm no expert on that sort of development.
Arguably, I'm not an expert on operating systems development either...
On the other end of the spectrum, There is this Canaan Kendryte K210 chip, which is a dual-core 64-bit RISC-V SoC, but only has 8MiBytes of on-chip SRAM, with no provision for SDRAM. An RTOS is of course the straight-forward choice for that, though people are apparently able to run a very slim Linux kernel on it as well. You can get various boards from Seeed Studio for $30 USD or less.
Is there something else that is a reasonable price? Less than $100 USD? Yes, I know, qemu is free.
