Have a question about the Next-Gen BeagleBone? Ask it here!

bluescreen

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

  • My question is about the 2GB emmc. While its possible to install a minimal Ubuntu/Angstom in 2GB, If one needs a install a desktop environment, a bunch of libraries (say QT), a bunch of programs and Apache, one will need more that 2GB. I understand that we can still use SD card but how can one parition the root filesystem between the eMMC and the SD Flash to really maximize loading speeds ? Is this something that TI is looking at providing solutions for? or is it simply hoped that the community will figure it out ?

     

    Because if it will be difficult to use the eMMC along with SD, most people (wanting to run Linux) will default to using only the SD card and the 2GB eMMC will not be used.

    Unix file systems and their descendants like most GNU/Linux file systems allow the file hierarchy to be distributed across devices any way the admins and/or users decide.  If I remember my Unix history correctly, one reason there are standard directories like /bin and /usr/bin and /sbin is that they ran out of space on the main disk and had to mount parts of the file system on other disks.

     

    For Next-Gen BBone, you can do things like have the kernel image and /bin and /sbin on eMMC, and put /usr and /home on SD card.  See the "mount" command.

    John, Agreed. If that is the case it would be nice to have an ready-made Gnu/Linux solution  or even just instructions on how to maximize the use of the emmc memory in such a partitioned setup. I have a rudimentary understanding of the 'mount' command but I suspect there may be more to it than that. I could be wrong. Either way, it would be nice to have more information on the implementation details of this solution.

     

    In the mean time, I'll take up your advice and read-up on the mount command
