Does anyone do a boot menu to load tftp images off a container on a NAS or something like that? Was thinking this might be a nice alternative to not have to change sd card boot images. I was having a look at amiga emulators too, feeling nostalgic for some old games and demos.

How useful is PXE boot if/when that becomes enabled? I’ve only used PXE for fog imaging tools and have no idea if it is useable for a real OS

Alehkhs posted:You can also have a Pi boot from SD card, but move the entire Root over to an external source. It needs the SD card in for turning on, but shouldn't be writing to it. Plus, it's reversible. I’ve done this in the past with atmel cpus and it works great. Just set the boot sd to read only and you’ll never have to worry about it! Also makes it easy to backup/snapshot your filesystems.

Somewhat related the nvidia jetson Xavier has a x8 Gen4 (x16 mechanical) slot right on it. It’s pretty nifty.

Chinese companies moving from ARM to RISC-V due to export bans etc makes me wonder what that may mean for risc-v security (or lack of it) going forward. Like will that increase the backdoor potential of IoT devices sprinkled about if they are running some customized risc-v that is CCP approved. Not that IoT stuff isn’t already hilariously insecure already.

Martytoof posted:I specifically used lead solder but I'm not sure if there's something about the Pi that would require an excess of flux? Oh probably if you are mixing between lead and lead free (the board probably has lead free on the pads) it would need a higher iron temperature to melt the lead free. Could be just the added time let the lead free that was on the pads flow.

Maybe a weird request, but does anyone know of a ribbon cable for the regular pi (40 pin header) that goes to a much smaller connector on the other side? Looking at using RPis to control development boards in pcie form factor and would be nice to have something a bit denser so to not take up as much real estate. Realistically all that is required are the SPI, I2C, UART and a couple more gpios. Been looking all over with no luck so far. Alternatively something like a compute module with the dense b2b connectors but with power input and an RJ45 ethernet jack on the board would be cool too The RockPi S looks interesting for something small.

ante posted:Use individual female to female headers, then hot glue them into whatever square configuration you like. Well, we know the interfaces we want but it's still in the spec design phase so form factor is open. Would probably get a cable custom made if there's no good options. It's the classic development card that has to have everything and the kitchen sink on it but also be able to sell it to customers as a reference design so can't stick too much on the board, otherwise I would just push for a compute module and then put the RJ45 on the main board. Simplest solution is just use a RPi 4B, 40 pin header with female header on the pcie and plug the card in directly (like a really big hat) but not sure yet if we'll have the space for that.

I just moved my pihole over to a container on my nas, was so easy to just save settings and reapply (although strangely the dhcp settings did not cone over). Now I need to think of what to do with this spare pi! One thing I was thinking about was get familiar with network booting so I don’t have to use sd cards, I think a netboot.xyz container perhaps.

Mr Shiny Pants posted:I am a big fan of PXE booting them. If you have a NAS that does NFS it is pretty slick. Needs a cabled connection though, but if you can, I highly recommend it. I am going to try to figure this out, I think probably using the netboot.xyz container on my unraid machine. Maybe something to do if I'm bored on the weekend.

Saw the BliKVM video on Geerling’s video feed, and that is perfect for using as lab host controllers. Does anyone know if pikvm install supports containers? I would run that for test scripts. Seems like the hardest part will be finding a compute module though.

Anyone ever use a Tiny Pilot KVM (https://tinypilotkvm.com/)? Looking to get an IP enabled KVM for work and looks like a good option, with it being plug and play with no fiddling around required. I won't be the one to maintain it so it can't be super linux complex etc. Not exactly cheap by Pi standards ($399 for the pi and enclosure with hdmi input) but the ease of getting it running plus the fact it is actually available to purchase are big plusses

pzy posted:I haven't tried Tiny Pilot but I swear by PiKVM: Oh nice, I had thought the pikvm hats were just a one off kickstarter thingie. There is also one that takes a CM4 you can buy from aliexpress. I’ve ordered one of the tiny pilot ones to try out, possibly will get one of those assembled pikvm to compare. This will be for remote controlling systems and may need some out of band stuff like external relays for power and reset along with voltage monitoring, so better than any of the other ip based kvms I have seen..

And then it's going to really start pushing out ARMs for the main CPUs for a lot of things! Huge growth potential.

Question for anyone who maintains a bunch of Pis.. We have a bunch of Pis deployed as USB UART <-> Ethernet (and some other minor function) devices for test setups. The Pis are not able to access the internet. What would be the best way of doing updates on these? - Some kind of ansible playbook that does offline installs on .deb files - Similar to above but do a reverse ssh tunnel from the Pi to a machine that is internet connected to grab all the apt-get stuff (IT might frown on this) - Just buck up and update all the microSD cards manually - other?

VictualSquid posted:Are they connected to an intranet? If yes, you could just setup a local mirror of the raspibian repositories and point your updater to that. Yeah they are accessible on an intranet, is pointing to a file share good enough? I will have to check if they can mount. I would also like to move to either making the boot section read only and mounting network folders as file system or net booting the whole thing at some point too. I’ll look into how to mirror the repository locally, thanks!

We deploy rpis in a lab to act as control/uart interfaces to test systems and I continually have to insist that we NOT attach them to the web enabled power supply because if people are just shutting them off willy nilly that is gonna gently caress the sd cards really quickly. I still get pushback and a lot of “what if we need to power cycle them remotely??” To which I say well fine do what you want just understand you will have to come in to replace the the sd cards then. I would like to move to a pxe netboot but our IT has things far too locked down to even attempt that.

cruft posted:Is the concern the media, or the filesystem? Yeah, filesystem, I got em twisted. Corrupting the card will cause someone to have to go in and swap. My argument to not being able to switch off the power to the pi is that if os restart doesn’t work you need to go in anyway, and it removes the possibility that someone accidentally powers off an outlet with a running pi on it. It’s still mildly chaotic in the lab so this can happen. I think perhaps setting up the web power to lock certain ports might be a good option too but overall it just doesn’t seem necessary to have that control over the power input. As for the lack of netboot it’s a whole thing, IT is ridiculous. I might be able to get them to allow it to a staging server. I have given up trying to have something like FOG for reimaging servers because that requires some dhcp control iirc and that’s not gon happen!

I got some cheap PoE splitters with USB-C and it owns not having to have a wallwart for the pi (or have to bother with the hat as all the pis were already in small cases that wouldn't fit hats) Only drawback is only 100Mbit but eh should be fine.

If you have a PoE switch there are some inexpensive ethernet/usb-c splitters that work pretty good. the basic 5V/2.4A ones seem to work fine for our pretty basic needs (just a UART relay really)
