00:33 <cyrozap> I had a bit of a cursed idea recently. You know those USB 3.1 Gen2-to-NVMe enclosures (e.g., https://plugable.com/products/usbc-nvme/)? Well, I was thinking, what if we could use a chip like that to connect an FPGA to a computer? In other words, emulate NVMe in the FPGA, then let the UAS kernel driver handle all the I/O, and you can issue commands by doing uncached reads and writes to the block device

00:33 <cyrozap> that appears. The benefit of something like this over an FX3 is that you'd need a lot fewer pins to reach the max speed of the bus, since it's PCIe, and you don't need to define your own interface with an FX3 or FT601.

00:34 <whitequark> this is like a high speed, more cursed version of UF2

00:37 <balrog> cyrozap: what bridges do those things use?

00:37 <balrog> > JMicron JMS583, Asmedia ASM2362, and Realtek RTL9210

00:37 <cyrozap> Some use the JMicron JMS583, others use the Realtek RTL9210.

00:38 <cyrozap> Oh, yeah, I forgot ASMedia has one, too

00:41 <cyrozap> whitequark: UF2? I assume you're not referring to the Microsoft file format or the nRF52 bootloader?

00:43 <cyrozap> Oh, you were referring to the Microsoft UF2. TIL: "UF2 is a file format, developed by Microsoft for PXT (also known as Microsoft MakeCode), that is particularly suitable for flashing microcontrollers over MSC (Mass Storage Class; aka removable flash drive)."

00:44 <balrog> oh god that shit

00:50 <kc8apf> Microsoft has another one. I'd have to look it up.
