Very recently I recovered my rock too. I'm about 20 hours in. Any repository or helpful documentation to save part of the 80 remaining hours? pleaaaasee

1.) Forget about EMMC, it's gone and not supported by anyone. 2.) Boot is only possible from microSD card. USB is not supported. 3.) Build BareBox with https://www.barebox.org/doc/latest/boards/rockchip.html Use `rk-splitboot` to split FlashData from the original boot loader, other option doesn't work. Build it, it will create barebox-radxa-rock.img. It's .img, not the .bin. Write an SD card as in the instruction. 4.…

Woow HUGE thanks!

I have a Jetson nano. It's a nice thing for what it is, and the price. But, the software misses the mark by a lot. It's still based on Ubuntu 18.04. Want python later than 3.6? Not in the box. A lot of python modules need compiling, and the cpu is what you'd expect. Good for what it is, bad for compiling large numbers or packages. They run a fancy modern desktop based on the Ubuntu one. Sure, it's Nvidia, gotta be fl…

FWIW, I got a review unit and it ships with a much lighter desktop environment (LXDE) this time and is has a swap file enabled by default. I guess that was needed to ship a 2GB version, but overall it seemed a little better thought out. They also include a wifi dongle in the box. It still only has Python 3.6, but OpenCV and numpy are pre-installed correctly this time so you don't have to compile them which is an impr…

I did switch mine to LXDE, but it was a faff to do and took ages. I imagine the only way to make this thing slower is to swap to an SD card.

I'm not doing anything with mine that involves OpenCV, I didn't realise one of its flagship examples was also messed up in the box.

Oh! And I just dug out my script to rebuild if I need to. I forgot a few more annoyances:

* tensorflow isn't installed by default, and it's not obvious how to do the install because you have to specify NV's repo: pip3 install --pre --extra-index-url https://developer.download.nvidia.com/compute/redist/jp/v44 tensorflow

* openai gym won't work unless you specify archaic version 0.15.3, there's a buggy interaction between it and NVidia's X11.

* lots of packages need installing that should really have come by default, or were broken by default [eg numpy]

I want to setup something like this for my daughter's primary grade school meetings using Zoom. Any suggestions? Are the Pis or this device up to par now for such use case? I totally do not like Chromebooks, and standard laptops are an overkill.

Given that you also need a screen, keyboard, mouse camera and mic, I don't know if it is better than a laptop for your application.

You can update it to Ubuntu 20.04 pretty easily. (using a Xavier as a desktop with that) If you don't need CUDA, you can outright use regular Fedora, which uses nouveau. (no reclocking issues or such on Tegra)

If you don't need CUDA, then save money, heat, and support issues associated with a second-string product and just get a rpi4. The entire point of the Jetson is that there's a non sucky GPU that can do AI at the Edge.

Just curious, any guess why it doesn't come with the latest Ubuntu and Python pre-installed?

Yup, just buy a cheap Chromebook (maybe used) and save many hours of labor/setup and quite possibly even some money.

tl;dr: It's the same device as before in terms of processing, but with less RAM and fewer connectivity options (and therefore cheaper)

More than that. They dropped Display Port, the second CSI Camera Connector, the M2 slot, the USB slot and replaced the barrel jack with the USBC. Thats a decent downgrade of capability

Removing the second CSI Camera Connector is what immediately killed it for my use case :(

What are the use-cases for a GPU-accelerated single board computer?

Anything that is not mass produced, needs to have a small size or weight and needs 3D graphics or computer vision. For instance, imagine a bike rental startup that wants to do traffic sign recognition integrated in their vehicles.

NVidia don't see the point. There are a few forum threads where NV respond "why do you even want that" or "you can get ubuntu 20.xx from a third party".

Forgot the most important one - power it by using power cable that came with it and the 5V _2A_ adapter. It will kernel panic at random places if you power it from the USB port.
