OT, sort of, but a while back I saw one of these... "Pi-like" boards that had two Ethernet ports. It also had significantly more horsepower. I'm wondering what might be recommended choices at this point for someone looking for an inexpensive, wired MITM / Firewall platform. P.S. It would be great if it also had decent on-board wireless for e.g. making a portable hardware firewall device.

seriously? (seriously seriously)? It depends on if you're okay with the chinese having a backdoor, at the firmware level. (to the tune of '//gotroot!!' in the source code, and dropping to root.) if you're okay with it, you have a LOT more options than if you aren't. perhaps if we start having dedicated routers and networks for the backdoored insecure stuff they'll start realizing that at the end of the day they're be…

I'm curious to see this for myself, do you have a source?

The BeagleBone was great when it first came out. Then the Raspberry Pi came out, and has a bigger community, higher performance, and lower price. Compared to the RPi 3, the BBBW seems like ... too little, too late?

Does RPi have PRU co-processors?

Nope. Would be awesome if they did though.

Does the RPi3 still require an SSD Card for the file system? Edit: A warning about the TPS65217C on the BBB. The power supply needs to come up in (I think 50ms) or it'll fail to boot.

It needs a microSD for the stuff in the /boot partition (kernel+devicetree files+firmware blobs+bootloader), but everything else should be able to live on an external USB device.

USB+ethernet both use the same connection to the CPU, and it's a USB-OTG implementation basically hacked to act like a USB host, but it's possible to host the filesystem there.

The BeagleBone Black has always targeted more embedded applications. Raspberry Pi's recommended embedded models are actually worse than this.

Yup. I've worked with a couple companies now that use BBB or derivatives thereof in shipped hardware. Mostly managing other hardware, e.x. battery packs. It's a cheap off the shelf solution, and with it being open source hardware it seems (I have not been part of the procurement process) that they're easier to source in bulk. The Raspi has always struck me as exclusively targetting the hobbyist market.

The board SoC quality is very good. However, it can not compete with e.g. the CHIP SoC board [1], which costs just 9 USD + shipping with similar specs (I have two CHIP running 24/7 without any additional cooling, running rock solid -even in summer, at 35-40º C indoor-). The only thing that would make me consider buying the BeagleBone Black Wireless is the two built-in microcontrollers ("PRU" processors [2]), for real…

Unfortunately even though I 'bought' a CHIP some 6 months ago I have yet to actually receive it. It's very easy to source a BBB. Hopefully in the future thy become more available. Though I fear that will come with an increase in price.

That's odd - I ordered my PocketCHIP in June and received it a week ago.

anyone know of any good resources, tutorials, books, etc. for putting the PRUs to good use? those seem to be the defining feature that separates the BBB from the other SBCs.

I can recommend "Exploring BeagleBone" by Derek Malloy which offers a very gentle introduction to the PRU with some mildly advanced examples. Also, a shameless plug with more PRU code examples in case you are interested to use Rust rather than C for the glue code: https://github.com/sbarral/prusst

The link at the bottom goes to https://beagleboard.org/wireless which isn't working for me, but https://beagleboard.org/black-wireless works. Mouser lists the price as $68.75 and element14 as $99.25; neither has any stock yet. There are hardware design source files on https://github.com/beagleboard/beaglebone-black-wireless , including a PDF schematic: https://github.com/beagleboard/beaglebone-black-wireless/raw... w…

Can it be that those prices are imaginary until there's stock? It seems like a nice board (I have a old BBB, with ethernet, and it's solid), but the CHIP [1] gets you wifi and BT for $9... 1: https://getchip.com/pages/chip

Beagleboard's come with PRUs, for which, if you need a lot of very fast GPIO, there's no substitute. I've driven 9000 LEDs at 100fps with Octoscroller

I have a few chips too. Running one as a jukebox. Not sure what to do with the others yet. What do you use yours for?

What kind of OS do you typically use with the BB? I know the RPI has noobs/rasbian, but is there something comparable for the BB?

Plain un-customized Debian is what it comes with. Debian and Ubuntu are both popular, but you can run almost any distro.

Or OpenBSD. http://www.tedunangst.com/flak/post/OpenBSD-on-BeagleBone-Bl...

I also think all governments should collude and there should be like world peace ¯\_(ツ)_/¯ - meanwhile they should fear for their people, and have to nominally follow constitutions. I guess I can keep dreaming though.)
