ante posted:Oh poo poo, might be almost the year of the I wish. Those things are so drat expensive. More messing around with the Jetson Nano. It seems to have formidable hardware codec ability. However there is no way to use it for video playback. The hardware may be HDMI CEC compliant but nVidia doesn't offer any software support for it. So technically it could be a great media device but lacks software support. It's not what I bought it for, but it's interesting to see what it can and can't do.

Is the lifespan of the SD card an issue for use as a daily desktop substitute?

KICK BAMA KICK posted:Is the lifespan of the SD card an issue for use as a daily desktop substitute? Yeah it is definitely problematic. You could do a ram disk to store logs and other ephemeral frequently written stuff (can google around for tons of guides on it), or IMHO now that the USB buses are super fast I'd just throw an external drive on the Pi 4 and boot exclusively from it.

Given the jump to the A72, which seems like a drastic jump from the more traditional broadcom that would only boot from SD, is it super likely that USB boot should be enabled within a couple of weeks of release? USB boot would be fantastic

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

They confirmed that USB and network booting is on top of the priority list and will be implemented "soon".

I was looking into USB Boot and the guide says that the procedure to set it up is permanent. Does that mean that it permanently can only boot from USB or that the Pi permanently has the ability to do so? if the latter, why does that matter?

Boot from SD is probably lower power overall. USB thumb drives can get quite hot. What is the procedure? Do you have to cut a pcb trace or something?

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.

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.

I guess maybe if you have a pi set up in a way meant to be secure, enabling usb boot would allow someone to attach a usb drive, reboot to it and then access... Something.

My guess is that there will be an 8GB variant, but will cost > $119 due to fitting 8gb high quality ram in a tiny chip is moderately expensive. Selling a raspberry pi board for over $100 is not good branding as they are all about the $35 price point marketing. 2gb and 4gb for under $60 is a great sales story, everybody loves that narrative and can buy in to it, what a wonder. If they were to launch their $120 8GB model with the relatively cheap 2 and 4gb models, the story would be "omg $120 is outrageous, highway robbery, might as well buy a new Chromebook at that point" terrible sales story, makes your product launch a net negative If you launch the 2 and 4 now, you get the initial generous press, see how sales do, then model demand for the overpriced 8gb, quietly release it as a limited edition model for raspberry pis 8th birthday in February 2020

I am guessing they have prototyped and tested the 8gb. Probably waiting on RAM prices to drop to release commercially. Also raspbian is currently only 32bit. Maybe next year if everything falls into place they will drop the 1gb model, price the 2gb at $35 and release the 8gb along with aarch64 build of raspbian.

I doubt you'll see bigger ram on the Pi 4 board as it is currently. I would bet they're designing a compute module and motherboard that just breaks out PCIe lines, memory DIMM slots, maybe a SATA controller and ports, etc.

wolrah posted:That's just for the Pi 3 and later Pi 2 models that use the updated SoC. They have USB/network boot support in beta in their boot code but it's not enabled by default, so you have to set a one-time programmable bit (basically an e-fuse) to enable it. Once enabled it can not be disabled, but the device will still boot from SD. It'll just take a little bit longer as it checks for a USB device. Ah, cool. I'm using a 3B+ so I guess I'll look into finding an enclosure for my various old hard drives to run the pi off that instead of the SD card.

does anybody know where I could find headless installation images for the rPi 4? I don't have a fitting HDMI dongle and I'm not about to buy one because it's supposed to run headless anyway. Ubuntu Server has these nice images that boot up without configuration and allow access via SSH, but I can't find anything for the rPi 4 yet. The old images don't work. edit: dropping an empty file named "ssh" into the boot partition of raspbian enabled SSH and solved that problem. eames fucked around with this message at 11:47 on Jun 27, 2019 |

eames posted:edit: dropping an empty file named "ssh" into the boot partition of raspbian enabled SSH and solved that problem. Glad you found the answer. Also if you drop a wpa_supplicant.conf in there it'll automatically install that and start up wireless on boot, in case you ever have a need for a wireless Pi that you don't want to have to plug in to a LAN first to set up (especially useful for Zero W).

Something handy to have too if you deal with a lot of little Linux-based boards is a 3.3V serial to USB converter like this: https://www.adafruit.com/product/954 Every board usually has a serial port exposed on GPIO pins and you can generally get to a login shell there. It's handy for hacking on little embedded devices like routers, cheapo game consoles, etc. too.

Played with the new rPi a bit and the performance is good as expected, easily saturates gigabit without encryption, syncthing over LAN to an encrypted USB 3 drive is ~400 Mbit, SMB ~650 Mbit. Pretty decent considering it has to do everything in software. Next up overclocking and before i'll put it in the dedicated raspberry-pi-in-case-i-need-one-but-i-wont drawer.

I have a recalbox pi and I'm looking to upgrade to hopefully get N64 emulation more stable. Do I need to bother with 4 gig ram for RPi4 or just stick with 1-2 gigs? I can't conceptually see more ram as better but I don't understand the underpinnings of emulation well enough to fully discard it.

RAM is one of those things where you either have enough or you don't. If you have enough, adding more is nearly meaningless (not entirely meaningless when running a modern OS because "free" RAM is often used for caching), but if you don't have enough adding more is usually the best thing you can do for performance. Any time you run entirely out of RAM with a modern OS it fakes the extra RAM you need using the hard disk, which is many orders of magnitude slower. Or it just crashes. So the question is, are you running out of RAM on your current platform?

On the serial subject there's lots of options. That posted USB serial dongle, or one that has a mini or micro connector. There's also RS232C, wifi via something like an Esp8266, or Bluetooth via an HC-06 or HC-05 module. I've used all of these for various reasons. Depending on device (adapter or SBC) , sometimes the USB adapter can be an issue. Even when it's set up to be USB powered, a high on RX (in terms of SBC) before the device is powered up can cause some really weird boot issues. Just putting that out there in case anyone finds themself with a weird boot problem.

Would this make a good Gigabit router if I bought a USB3->Ethernet adapter? And not a wifi access point, just a plain router (and maybe VPN server/client if the CPU is good enough)
