I'm guessing you're after the bare MCU, but for others, you can get a nice relatively cheap prototyping board with the chip from Sipeed, for example:

SeeedStudio has a few others as well:

Just note that you need a relatively new J-Link (v10 iirc) to program RISC-V cores using J-Link, alternatively for the Sipeed Longan boards, pick up two of them and you can flash one with a provided debugging/uploading firmware.

Yes, the Longan Nano is very nice but I'm also interested in the bare chips. Seeed also sells cheap JTAG dongles that work with their RISC-V boards, which is nice.

I've been using a clone J-Link which works pretty good. I got it probably 5 years ago, so it's impressive that it works. I think I'm using a patched version of openocd with it though.
