Mini-PCIe: Half vs. Full

Under hardware features / mini-PCIe, there are several links to products which are Full length (50.95mm) expansion cards, and will not directly screw onto the board, since it's mounting holes are for half-length (26.8mm) cards. There does exist 1 adapter/riser that should allow full-length cards, at additional cost. Propose to split adapter list to emphasize which would require an adapter (different sub bullet point). Or perhaps only hyperlink to cards that have been tested and known to work?

Thanks for the info Spawnflagger, I wasn't aware of this when I wrote those links. Actually none of the cards I linked to have been tested on Jetson TK1, I only know that at NVIDIA they tested a few mini-PCIe cards and those did work but I don't know what cards they actually tested. So I just did a search of various mini-PCIe cards and posted links to them.

I'll move the links to a separate page "http://elinux.org/Jetson/mini-PCIe" with the info you posted here, and keep full-height and half-height mini-PCIe cards in separate sections. If you end up finding other useful half-height mini-PCIe cards, feel free to add it to that page, mentioning "(untested)" or "(tested)" if you do actually test one. (Note that some devices will need kernel or firmware driver support before it works).

Thanks Shervin. I will be getting a Jetson TK1 soon, and have also ordered a Syba half-mini PCIe Gigabit NIC (Realtek based). I'll report back to confirm/deny that it works. The full-card to half-slot adapter/riser I mentioned is this MM3U+DB3U (untested).

which CSI-2 MIPI cameras are supported?


Please could we have a list of supported cameras? with links to suppliers would be handy...

I've bought into a few boards over the years, which had CSI-2 MIPI connectors, but no cameras were supported.

it seems clear that currently not one CSI-mipi camera is known to work with Jetson,

Jetson TK1 is a very new board, so I'm not aware of anyone that has built a CSI MIPI camera adapter for it so far. But the Tegra K1 SOC is already used in numerous phones, tablets & Google's Project Tango, all of which use atleast one CSI MIPI camera, so clearly CSI MIPI cameras are supported. The problem is that there isn't a single CSI MIPI format, so you need to design custom hardware & firmware & software for each specific CSI MIPI camera you use.

01:25, 15 July 2014

TK1 is sold to public, ie me... public has no means to "design custom hardware & firmware & software for any specific CSI MIPI camera"

there is an expectation that one or more CSI cameras will be available.

see Raspberry Pi.

03:44, 18 July 2014

I agree that ideally a built commercial CSI camera board should be tested on Jetson TK1 and documented, but unfortunately NVIDIA has not done this and might not do it for many months or years since big customers won't want to use the same specific CSI camera board, and makers will be happy enough to use a cheap USB webcam, so NVIDIA hasn't made it a priority.

PS: Raspberry Pi did release a CSI camera board after the RPi became hugely popular, but Raspberry Pi is also about 100x more popular than any other embedded ARM board, so they have more reason to work on things like this, whereas Jetson TK1 is still very new & unknown so NVIDIA hasn't put many resources into add-on devices as yet. Hopefully this will change in the next 1 or 2 years, particularly for CSI camera & Arduino support!

this is as received...

Hmm perhaps upon delivery (with R19.2?) it has been formatted as 12G. However if you flash according to the directions it will reduce to 8G. I think this is to reduce the flashing time over USB.

13:16, 23 July 2014

Yes Dustin is correct, we ship it with 12G but if you follow the custom Linux flashing instructions it gives you a smaller partition since it can take an extra hour or so of waiting for that extra 4GB of space during flashing. We are likely to simplify it so that both the shipped device and the custom instructions give you a single 12-13G partition.

"a micro-B to female Type-A adapter is included"

Quick Start Guide and physical item supplied is not female, but male micro-b to male A USB.

What purpose does this lead have?

Can someone please check with nVidia and advise?

The lead may be for connecting to another PC?

03:42, 14 July 2014

Early Jetson TK1's were sold with both a micro-B USB cable (to flash the device) and a micro-B to female USB-A adapter cable (to have a second USB 2.0 port). The adapter cable was later removed from sold devices for a while (since someone at NVIDIA thought it wasn't too important), but I think future Jetson TK1's will be sold including the adapter cable (since I convinced people that it actually is important!). So some customers received that adapter cable for free while some customers didn't.
