Support status for Seed studio boards

[antoinefaure]

Hi team,

Thanks for the great work. I'm already using meta-tegra on a reComputer J4012 and it's working great so far.

I'd like to test the super version, but before I ask my company to buy it I'd like to make sure that it's supported in meta-tegra. It seems to be the same carrier board with an extension board for the extra ports, so from my understanding I should be able to use the same p3768-0000-p3767-0000 machine. Is that correct ? Has someone tried it ?

Regarding the support mode, I assume there is no software difference either ?

Thanks in advance,
Antoine

Yes, the J401 carrier board that's in that J4012 box is sufficiently compatible with the NVIDIA p3768 carrier that you can use the stock machine configuration.

We upgraded the stock machine configurations for it when "super" mode came out, rather than treating that mode separately. You should see "super" in the device tree name.

Thanks for your comment @madisongh !

When you say "sufficiently compatible", are there some differences I should be worried/aware about ?

And regarding the j4012 super board, any idea of what might not work out of the box ? By the look of the schematics, it seems that the additional ethernet port is on a PCIe port meaning that it should be discovered automatically if the drivers for that chipset are present ? I'm trying to get an idea of how much of an effort it's going to be to make this board work. If anyone has used it I would be keen to get your feedback please!

Good to know about the super mode, thanks.

Cheers,
Antoine

Not that I know of, but you never know...

No, but their documentation points to their "getting started" page that has links for downloading a customized L4T, so my guess is that there are going to be at least some other drivers needed, or device tree modifications, to make some of the hardware work. Might be best to walk through their docs first using their L4T, test everything, then work on your OE/Yocto OS build and look at what needs to be added/adapted.

All right, thank you very much for your help, it's greatly appreciated! I'll have a look at their L4T image.

Thanks,
Antoine

I already have meta tegra working on j4012, I transformed the dt overlay to be used as an external devicetree see https://pastebin.com/7C8QXgWz and in yocto machine side I used only the som with this config conf/machine/p3768-0000-p3767-0000.conf (16GB)
for now here the status:
the linux-yocto boots fine without kernel panics..., the gpu works fine, the internal ethernet port works, usb ports works, serial console works, hdmi also works, but I didn't check for wifi or the second ethernet port maybe need to add some drivers.
