There is a lot of excitement about TI's Next-Gen BeagleBone. If you have a specific question about its performance characteristics, tech specs, or anything else, post it as a reply to this thread. We are working closely with TI and will make sure to respond to your questions.  Thanks everyone!  Sagar

    Hi,

     

    A couple of questions, most important (to me) first:

     

    Can you confirm the impact (if any) on the 6 onboard UARTs (esp UARTs 1 thru 5)

     

    Most of my projects use them extensively (Yes, including UART3 that doesnt have TX and RX pins brought out, CTS and RTS pins do have their uses), and in fact one or two projects I'm having to find "innovative" solutions as ideally I'd have 5 or 6 fully operational serial ports image [And yes, proper serial ports are needed for a lot of these for various reasons, including timing precision and an "RF Hostile" environment]. The 6 (4 fully operational) serial ports is one of the major reasons I prefer the bone to the Pi.

     

    Will all the pins still all be brought out the way they are on the current Bone ?

     

     

    Is there any audio onboard, Or do we still need the audio cape for that ?

     

    Will the current bone still be avaliable once production of the new bone ramps up ? (This will be important to me depending on the implications of the new bone on the UARTs)

     

    And finally, what is the colour of the board ? I know there's a new "bright" colour coming, but is it going to be avaliable in two colours, or is the new "bright" colour the only option ? I quite like the white of the current bone. The unzipping pic suggests dark green. That would be so...common image , and certainly isnt "bright" [and more seriously probably harder to read the legends on the board]

     

     

    Best Regards

     

    Iain

    And just one more question.

     

    Is the PRUSS present on the new 'bone ?

    One of the nice things about this project is that it's being run very open. The kernel patches to support the new board are already in public repositories! You can see the patch to enable the eMMC and HDMI here:

     

    eMMC: https://github.com/beagleboard/kernel/blob/3.8/patches/capebus/0006-beaglebone-enable-emmc-for-bonelt.patch

    HDMI: https://github.com/beagleboard/kernel/blob/3.8/patches/hdmi/0004-Add-capebus-override-and-pinmux-for-da8xx-dt.patch

     

    From those, I extracted the following:

     

    eMMC pins on header: P8_5, P8_6, P8_20, P8_21, P8_24 and P8_25 (gpio1[21:24] aren't on the header)

    HDMI pins on header: P8_[27:46]

     

    eMMC interferes with:

    UART1 (P8_19, P8_20, P8_24 and P8_26) TX on P8_24

     

    HDMI interferes with:

    UART2 (P9_21, P9_22, P8_37 and P8_38) RTS/CTS lines on P8_37 and P8_38

    UART3 (P8_34, P8_36 and P9_42) RTS/CTS lines on P8_34 and P8_36 -- though I don't know where the RX line is

    UART4 (P8_33, P8_35, P9_11 and P9_13) RTS/CTS lines on P8_33 and P8_35

    UART5 (P8_31, P8_32, P8_37 and P8_38) on all lines

     

    That leaves UART2 and UART4 open as long as you don't need hardware flow control, otherwise you'll need to disable one of the interfaces.

    Yes, the new Bone will include the PRUSS.

    Thanks for the feedback on the UARTs. Disabling the HDMI and the eMMC will be no issue for some of my applications (The serial ports are more important)

     

    Looks like the affectedf UARTs are still only a pinmux away, and at worst a patch -R image and recompile

     

     

    Thanks again

    Thanks to devicetree and capemgr, you shouldn't even need to recompile (or often even reboot) to load entirely new drivers.
