OXNAS - Command line to determine if PCI or Not?

I'm going to put together a tutorial on setting up Debian on the Pogoplug v3/Pro leveraging @bodhi's work.

What's a easy way via command line (from the stock Pogoplug OS) to determine if the Pogoplug is a Pro vs Classic? Basically to help determine which appropriate DTB file (ox820-pogoplug-pro.dtb or ox820-pogoplug-classic.dtb) to use.

Thanks

Thanks gray.

There are a few ways. Easiest is the command lspci, which I believe should be there. If you see nothing coming back, its a Pogo Classic. If a Pogo Pro, then PCI is populated.

I'm pretty sure there is no "lspci" command available in the stock Pogoplug OS. I can't verify because my Pro is already running Debian.

Maybe a "dmesg | grep pcie" is sufficient. I believe I have a unmodified P21 (OXNAS) somewhere to test on.

The problem with using dmesg is that the PCI driver should show up, since the same kernel is used for both versions. I guess you would have to look back to stock dmesg in both boxes to know for sure.

I kept it simple and defaulted to the pogoplug classic dtb since it works for both the PCI and non-PCI version. Enabling Wi-Fi/PCI can be done separately.

I think that's a kludgy approach! you should be able to determine which box. If not possible, then ask the user to figure out which box they have by looking at the model number (not rocket science!).

if you ran the dmesg output and looked for module load failure, wouldnt that show if the pci loaded and that could be used as proof of the "type"?

True, it's a little kludgy. However, defaulting to the pogoplug classic dtb guarantees a bootable system regardless of which Oxnas device the user has.

Setting up Wi-Fi requires additional packages and configuration anyways, so if the user has a Pro and wants to use the Wi-Fi, it's one additional command to update the env to point at the pogoplug pro dtb file.

Yes, it's not rocket science, however I think you maybe overestimating people on the internet. I've had at least two users brick their Pogoplug because they followed my PPv4 tutorial and installed the PPv4 uBoot on their E02 and Oxnas device. Why would they do that even though the tutorial clearly states its for the PPv4? Translation issue? Lack of reading comprehension? Pure stupidity? I don't know. :)

I found a good way to detect it, but it requires me writing a script which I don't want to do at this point.

For the record, it documented in the archlinuxarm oxnas installation script - http://os.archlinuxarm.org/os/oxnas/oxnas-install.sh

No. Carelessness and excessive risk taking, and so bricking is a ritual :)
