Black-eyed Pies reel from BeagleBoard's $45 Linux micro blow Open-source hardware outfit BeagleBoard has formally announced a major revision of its BeagleBone board computer that ups the spec and downs the price. The BeagleBone Black's single-core processor jumps from its predecessor’s 720MHz to 1GHz. It’s a Texas Instruments AM335x system-on-a-chip, which uses ARM’s Cortex-A8 …
Upvote on the Full Linux thing- the article is wrong - it's not a cut down version - it's a full version. In fact, I'm not even sure what a cut down version of Linux would be, or if it even exists. As to speed - well, that's in the eye of the beholder. Quite a bit of the slow speed stuff has some interesting improvements in the pipeline...
This BB looks pretty good. As I said elsewhere, they must be selling close to break even at those prices - 5 chips on board compared to the Raspi's two must almost fill the $10 gap. TI might even be putting this out as a loss leader. I'd be surprised if the price stays this low.
There is a few cut down versions of Linux at least one which is still used - uclinux and elks.
These might be better for RiscOS than the pi (Afaik the graphics support for the beagleboard is the best - even though the pandaboard is better hardware there is no dual processor support in RiscOS).
You have to remember TI makes those chips (Or I think gets them made these days but they already have the volume) whereas the Rasberry PI has to buy from Broadcom.
Two chips on a Model A you mean, there's three on the Model B RPi - ok, one's stacked on top of another but you still gotta pay for 'em.
The large amounts of GPIO on this new Beagle are what makes it more interesting to me than the RPi, although I don't think the AM335x series can drive two framebuffer monitors, which is a shame.
It was the RPi that got all these new ultra-cheap SBCs started though, and for that I am eternally grateful.
Let the downvotes start.
Recently Ubuntu has become a pile of steaming dog droppings when compared to older releases.
More downvotes.
They seem to have a finger in all sorts of pies none of which appear to be making a difference to the quality of their core product.
Then they have reduced their non LTS support period to 9 months. WTF?
There are other distros available that run on a Pi etc.
Pi runs linux, ubuntu is a linux distro, is that not tenuous a link enough to count?
I used to use Ubuntu but not any more, moved away in favour of Mint, and I'd never consider using Ubuntu on a PI, I was looking at Arch considering the constraints. Running Ubuntu on a Pi is about as intelligent as running Windows 8 on a pentium 4. They've both got terrible interfaces, and neither would run very well on the provided hardware.
@Steve Davies 3: So it is, and yes, you caught me skipping subheadings. The flimsy excuse is that my RSS reader seems to encourage that, but it's a flimsy excuse.
I'm still confused as to the relevance of the particular objections given to the article at hand, though.
I have to agree there are better choices for boards like this and the Pi than Ubuntu. For starters with something this low powered you'd expect to be using LXDE, [black|flux]box or even XFCE rather than Unity. Heck, can Unity even run on something with less than 2GB RAM?
I would guess that's why Raspbian seems to be the default choice for the Pi.
WTF????
Let me gently explain by means of this buzzy stick.
RPi doesn't run UBUNTU!!!! FFS! <BZZZT!!!>
RPi is RISC/ARM architecture. Ubuntu runs Intel 386/AMD-64 CISC processors.<BZZZT!!!>
Ubuntu has not been compiled for the RPi. It never will be. No need. <BZZZT!!!>
(Damn, still breathing, I see...)
The RPi is not designed to be a desktop.* <BZZZZZZZZZZZZZZZZZZZZZT!!!>
That'll do it.

Last I looked, Ubuntu ran on ARMv7 onwards - and there were no plans to port stuff to support ARMv6 (as used by the Pi) so your first point is correct, your second probably incorrect (as I assume it was intended, difficult to say as it's rather vague) and your buzzer (IMO) is very annoying.
Yep, you're correct. Ubuntu's 'skunk-works' seem to have produced Ubuntu-ARM-on-a-server.
To test relative speeds. Doubt if it'll be ported o desktop, tho' interesting if they did.
The buzzer? Blame the BOFH for that. I took in as surety for a few beers he cadged off me...
So you upgrade from ARM11 to Cortex-A8, lose about 15% of the clock speed and lose the GPU?
Losing the GPU is a massive loss, unfortunately. Simply cannot see this competing with the RasPi. The lack of serious GPU means it won't draw in the cheap media centre crowd, so it'll lose out on a lot of the community support. And at the end of the day Cortex-A8 isn't *that* much faster than ARM11, especially when you haven't got an obscenely overpowered GPU to hand off all the interface work.
"You are correct James, strange that that is omitted in the main post though.."
Strangely enough, I thought all the comments about lack of video out were some odd humour I was missing ! However, seems not - luckily, from the article..
"The Black’s six-layer, 85mm x 53mm PCB holds all the above plus an HDMI port, 10/100Mbps Ethernet and a cylinder 5V power jack."
That's been in there since I first read it, honest, so not just dropped in.
I really wish people would stop comparing this to the Rasp-Pi... It's a completely different beast. It's not a mini single board computer, but an embedded controller that runs Linux... Like an Arduino, but different in many ways... It's also not correct to call it a beefed up Arduino or an Arduino on steroids... It's much, much more. I have 3 Beaglebones embedded in various projects that I've built... A 3d printer, and a couple of robots...
The BeagleBone is not a general purpose computer! It's not ever intended to be hooked up to a display/keyboard/mouse and be operated as a computer other than during development or debugging, it's meant to form the guts of some larger device as it's controller... I only ever communicate with mine over ethernet. It does not need and should not have a GPU of any sort...
Cheers,
Troy.
@Lose 15% clock: Aparently you failed math because going from 700MHz to 1000MHz is an increase in speed not a decrease. Also this quote speaks for itself : "Compared to the ARM11 core, the Cortex-A8 is a dual-issue superscalar design, achieving roughly twice the instructions executed per clock cycle."
@Lose GPU: I dont know whats specs you have been reading (Original BeagleBoard maybe?) but the AM3359 SOC has a SGX530 3D Graphics Engine...
"Aparently you failed math because going from 700MHz to 1000MHz is an increase in speed not a decrease"
It seems I was reading a previous revision's datasheet, where the CPU is clocked at 600MHz unless it's connected to a 5V DC power supply. Either way 2000MIPS, while a step up from the RasPi's, is not a substantial amount of CPU computing in terms of a modern OS - especially not when the CPU will be unable to hand off much of the graphics work.
"I dont know whats specs you have been reading"
I said lose *the* GPU, as in, it has a completely different GPU with much reduced capabilities. The VideoCore 4 GPU puts out something like 25GFLOPS of general-purpose compute/1GPixel of graphics. The SGX530 has about 20% of the power under its hood.
I'm not saying it's a bad device, I'm just saying it's not a device tooled up to compete with the RasPi. With the reduced graphics capabilities but massively increased GPIO and power options, it is clearly aimed at makers who want something a bit more capable than an Arduino without having to resort to the unholy Arduino/Raspi combination.
Wasn't part of the whole Pi idea to stimulate this kinda thing? Now I have the choice of two nano-PC-board-things to choose from. Cool!
Both are good as learning tools, one has more juice than the other, but one draws less power than the other. Which one is "best" really depends on the problem you are trying to solve.
"Wasn't part of the whole Pi idea to stimulate this kinda thing? Now I have the choice of two nano-PC-board-things to choose from. Cool!"
..and at that price, you can buy both, and whistle innocently, if you really want.
It's not that long ago that little industrial embedded boards cost more than a midrange desktop PC in many cases, this sort of thing is an embarrassment of riches..
Its an "cheap educational device" for learning and experimenting with
No, it's a "cheap educational device" for learning and experimenting with. An is used before a vowel sound. I tend to avoid pointing out grammatical fails, but an / a just irks me for some reason.
And now in an attempt to prevent downvotes, an actual response.
The Pi doesn't offer the power and speed I desire, but that's why I desire it. I've always wanted to experiment with cluster computing, why? I don't know is probably the best answer to that, But buying a load of PCs is expensive, even buying the cheapest parts these days, as is the space and power it would use. But with a collection of Pis it's quite possible to create a miniature cluster which could be used for experimentation. Not only that but ti's easily extensible too. And the lack of speed / power actually proves more benefit since it'll be easier (in my mind) t work out a performance boost for each additional cluster. single core 700mhz addes = % increase vs quad core added, % increase, how much is that per core, how much of that is due to the RAM, connection, etc etc.
The only thing missing from the Pi for me is gigabit ethernet. If it had that I'd be sold 100%, alas.

And now you can, sir - for USD 99:

@James 139 The educational element was primarily so that kids could plug it in and learn using the communal TV in the living room like so many of us did back in the 80's. I've never used any of my Pi's for that but I gather it is too slow to do dev directly on the machine, so in that sense it doesn't quite hit the mark as intended, as far as I can tell.
Perfectly possible to do dev work on the Pi itself, esp. teaching. Scratch works pretty well, as does Python (and C etc). You wouldn't use it for main line dev work, but then, you probably have a desktop if you work in that area anyway. I use a Ubuntu desktop and cross compile to the Raspi, simply because I have the ability to do so. The work could just as well be done on the Raspi itself, just slower.
Nah, its fast enough if your not worried about a gui, and really, you should NOT be learning about computers using a gui, its distracting and takes away from the development & hacking that you can do on a pi...
Personally I run mine headless, Just ssh into them...
