Used beaglebone since it's out years ago, it's a great piece of hardware and kind of kicked off the open-source-software plus open source 32-bit-CPU DIY hardware movement before everybody else. Then clone was up everywhere, from RPI to Intel to many small shops in China etc, even Arduino started to add 32-bit CPU boards, price has remained to be low so far. The only concern is that TI is not as active as before on it…

Didn't anyone else out there have a PandaBoard? And TI was probably smart to exit OMAP for phones/tablets when they did. It's too hard to beat Apple/Samsung/Qualcomm in this space now. (The Sitara/AM335x on Beagle is just an OMAP without the video DSP)

There were a not-insignificant number of companies who tried setting up build servers &c on PandaBoard & found the units failed fairly quick under any kind of sustained use. AFAIK BBB, although more limited, best I know remained reliable.

The BeagleBone does power management which the RPI doesn't. It's unfortunate that they didn't take this revision opportunity to boost the RAM and switch to USB3. IMHO.

> It's unfortunate that they didn't take this revision opportunity to boost the RAM and switch to USB3. IMHO. Well, the RAM on the Bone is DDR3 while the RAM on the RPi3 is DDR2. I'll generally take the extra performance over an extra 512MB. With respect to USB3, USB Type-C connectors are WAY more expensive than micro-B. We're talking like more than a dollar vs less than 10 cents. And USB Type-C cables are way more e…

You've conflated USB 3.0 with Type-C. Many many people ship USB3, many of them being fairly low cost wifi routers, but yes, they use USB 3.0 Type-A connectors, the big rectangular ones.

I'm also generally unconvinced the Type-C scaremongering is real. Difficulty now is high, costs are high, but it still doesn't seem as impervious a barrier as many people intone.

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 upvoted you in spite of your tone, because your statements are not undue. The AllWinner stuff is concerning because they weren't exactly transparent about things. However, the Octavo stuff looks like your bog-standard chips from BeagleBone/TI just all smashed onto the same substrate. You could decap the module and see if that's true.

I don't know if the threading makes it less than obvious, but I was simply answering this question:

>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.

There are a lot of very interesting, very cheap boards!

How is the software support for BeagleBone boards? Can I expect to get automatic kernel updates with security patches? Traditionally a problem with many boards is that you have to choose between running a distro kernel with incomplete hardware support but timely security updates, and running a board specific kernel that can't be safely exposed to internet-connected environment.

I had a student try to do an independent study research project using the BBB a couple of years ago. The experience wasn't good. We had a lot of trouble getting the thing to run with anything except the one kernel version that it came with. Porting over features from kernel modules done on earlier minor versions was a huge pain and not at all straightforward.

This has definitely changed. I'm using the current mainline kernel and it includes proper configs for the BBB. Works pretty much hassle-free.

I would have absolutely loved this if it were 5 GHz wifi. 2.4 GHz wifi in my apartment is practically useless, with ~40 visible APs from my laptop.

Are dual 5/2 GHz chips that much more expensive?

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?

The BeagleBone Black has better Linux support out of the box, doesn't require non-free firmware to boot, and is itself an Open Source Hardware design.

I haven't researched the BB in a while. Are there any BLOBs that remain (graphics?). Last time I checked it was the freest alternative I found.

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.

There are instructions here regarding how to set up an RPi3 to boot from USB: https://www.raspberrypi.org/documentation/hardware/raspberry...
