A few more things about the shipping info. These websites want you to pay to access the data, but some more information can be searched up for free, and some redactions can be circumvented.
Most if not all of these T239 listings are being exported by NVIDIA Corporation and imported by NVIDIA Graphics Private Limited, which is Nvidia's branch in India. It's presumably due to customs requirements for India or just SOP for this specific company that these show up so consistently, while other kinds of Nvidia- or Nintendo-relevant shipping that one could imagine don't seem to.
If the dates are to be believed, Nvidia is frequently shipping them all kinds of stuff, including retail and test boards for products both before and after public release. For that reason, I don't think the dates are super meaningful, as seeing a test board or prototype in one of these listings demonstrably doesn't mean that product is currently still in development. But, just to document the relevant ones:
- 699-12423-1099-TS1 shipments are listed between April 27, 2022 and August 20, 2022
- 699-12423-1099-TS2 shipment is listed on September 19, 2022
- 699-12423-1099-TS3 shipments are listed on October 31, 2022 and November 10, 2022
- CARPA X1 shipments are listed between July 28, 2022 and May 30, 2023
These dates match up well with the implied timeline of T239 sampling (or otherwise physically existing) around April 2022, per the interpretation of some Linux commits by oldpuck and others, and being finalized sometime that year.
By the way, Carpa X1 has nothing to do with Tegra X1. Carpa is presumably a codename, but X1 is a common type of revision number which we know Nvidia uses (such as on the SDEV-CPU-X0 prototype board posted in this thread before; more Switch-related examples
here).
So, what is Carpa? Based on the description of "T239 SW DEVELOPMENT PLATFORM CARPA X1," I speculated it could be another dev board with a DDK included. Well, the
HSN code for the E2423 boards classifies them as basically just an electronic device in the "other" subcategory, but the
code for Carpa puts it in the "video game consoles and machines" category. It would be tempting to assume this is related to Nintendo devkits, but Nvidia probably wouldn't primarily refer to those as a "T239 software development platform." I think it's possible it is another test board and/or DDK, and the HSN code is either just a bucket it got lumped into, or this could be for an actual Nvidia product such as a Shield TV. But even then, I feel like it would have a more identifiable codename and not mention T239 specifically in that case. So I'm not sure about this one.
One other difference to note is that the E2423 boards have China or the United States as their country of origin, while the Carpa shipments have Japan (all have India as the destination). The listings from China appear to be from NVIDIA Singapore Pte Limited, which is evidently in Hong Kong, not Singapore. The United States and Japan COO listings are supposedly both exported by NVIDIA Corporation.
