Pi vs BeagleBone-Black

Former Member

So, just over a year on from the initial availability of the R-Pi and the new BeagleBone Black is upon us.  They've obviously taken a leaf out of the RPF's playbook and produced a cost reduced version at a price only marginally above the Pi.

 

I find it interesting that the compromises are very different, for example there's a proper PMIC and the ethernet is not troubled by being connected to USB, however the on-board HDMI seems less capable.

 

Other differences are in the documentation, I'm currently viewing the pcb gerbers for the beaglebone..  Have yet to see any sign of those for the R-Pi a year later. There's even an up to date devicetree capable kernel too.

 

Technology has also moved on somewhat, we get a 1GHz Cortex A8 which is better than the Pi, along with various other stuff and lots more GPIO's too.

 

Ok, so it's clear that I like the look of the new beaglebone, and given the price I'm likely to put any further R-Pi plans on hold until I have a chance to play with this. It's also making things like the Olinuxino-maxi I bought recently look very slow/expensive while still being cheaper than the similarly specced Olinuxino-A13

 

Some details of the beaglebone-black here http://circuitco.com/support/index.php?title=BeagleBoneBlack

 

What do the rest of you think ?   I don't expect this to displace the Pi anytime soon, but I expect it to be very attractive to those people who don't simply want to put XBMC on it and duct tape it to the back of the TV..

    the only problems I still see are for realtively obscure devices.

     

    USB is not a bus standard for non-obscure devices.  It is a universal standard for all class-compliant USB devices using the shared class drivers, and it's also a universal standard for USB-compliant devices that provide their own drivers for the host architecture.  This means that all USB compliant devices of any USB version (up to 2.0) and of any speed and used together in any mix are expected to work even through multiple cascaded hubs, as they do in every other computer with USB host functionality.  Old and new devices are all supported, if USB compliant.

     

    Subject to attaching only USB-compliant devices, a USB-compliant host board should never fail to operate its USB system correctly.  (Devices that would exceed available USB bandwidth are validated at connection time and rejected in advance if their needs cannot be met, so that once the session is established it has a reasonable guarantee of proper operation.)

     

    The fact that the Pi's USB system does not handle the connection of completely USB-compliant devices of mixed types without dropping data or breaking USB sessions including networking is a very important fault.  The reasons for the failure are well understood after intensive engineering diagnostic work, and are well documented on the RPF site.  The fact that your own setup does not trigger the fault does not mean that others are as lucky.

    So what? Some (obscure?) USB stuff doesnt work very well. Ive got USB stuff that wont work on ubuntu desktops. I've got a usb socket on my car radio that doesnt work with some sticks. You are writing as if the raspberry pi is the only device that has usb problems. it isnt. Loads so. Its a shame it doesnt do everything, but hey, my ute won't go 200kmh. but it does do what I bought it for. Maybe some people dont have all they want out the usb, but a hell of a lot of people do. most of them in fact. You are wrong. I reckon the remaining issues dont add up to an important fault simple by working out the numbers.  its like saying any old product has an important fault if 0.001% of the people using it has problem. thats not true. Most products have some level of fault, and that level is acceptable if it only affect a low number of people. I've got some pos samsung phone, some stuff on it doesnt work very well and it should. So what.
