Hi All,

               We are developing custom board, has SOM module this includes OMAP4460, TWL6032, TPS623X. we are looking for Linux kernel source for OMAP4460 boards. plenty of Linux kernel source  is available for OMAP443x  but we need Linux source for OMAP4460. So  please tell us where we can find the Linux kernel source code for the same.

Thanks in advance,

    Hello,

    1. The official linux kernels for Ubuntu are:

    Official Ubuntu git tree:

     #git clone git://kernel.ubuntu.com/ubuntu/ubuntu-precise.git

     #git checkout -b working origin/ti-omap4

    Official TI-Ubuntu git tree:
     #git clone git://dev.omapzoom.org/pub/scm/integration/kernel-ubuntu.git

     #cd kernel-ubuntu

     #git checkout -b release_GLP1.6.8 ti-ubuntu-3.4.0-1489.22

    For build instructions you can refer to: http://omappedia.org/wiki/Ubuntu_kernel_for_OMAP4

    The above kernels are tested with OMAP4430/OMAP4460 reference hardware platforms (Pandaboard & Blaze board).

    2. Linux kernels for Android can be found at the release notes available in the following link:
    http://omappedia.org/wiki/Android:_Working_with_pre-built_binaries

    Best Regards,

    Yordan

    Hi Raghunath,


    The only official kernel releases for Blaze Tablet are the Android releases.

    Ubuntu kernels have not been tested on Blaze Tablet.

    Hello Raghunath,


    As I said Ubuntu release from TI has been tested only on Blaze & Panda board.

    It should be possible to run Ubuntu kernel on Blaze tablet, since omap devices are capable of running this os, but as I said it has never been validated (no official support for running Ubuntu on Blaze tablet), which means:

    1. You need to make modifications to the kernel, in terms of board file, muxing, clocking, etc...   (in order to make the appropriate configurations you will need Blaze Tablet schematics as well)

    2. There is no TI guide on how to port ubuntu on blaze tablet. 

    This is a lot of work to be done, having in mind that there will be very limited support.  I would recommend using android.

    Best Regards,

    Yordan

    Thank you very much Yordan.

    But I am concerned.  If I build the OMAP4460 by cloning the GIT repository and following directions at omappedia.org, will I be missing any changes that Variscite added to the kernel?  I have been talking to them - and they are indicating that they have altered the SPI/kernel software.

    -thanks

    Oops!  I put a follow up in the wrong thread.  And I don't see a way of editing/erasing it.

    Hum, well, the question of building a Ubuntu kernel for the Variscite OMAP 4460 is still forward in my mind.  If any can answer my question I would appreciate it. 

    I think I should be looking for a BSP or Variscite Board Support Package which might / should contain the files that will make the ti.com embedded Ubuntu kernel work on the Variscite OMAP4460 board.  If any can point me in the right direction it would probably save me tons of time.

    Thanks.
