Hi all.

Here is the logcat output from my custom bbb board log, using Android 4.2JB(Kernel 3.2).

As per below log looks like gralloc module is not loaded. Please anyone can comment on the same.

    Hello,

    We tested with our Beaglebone Black and we have a similar logcat.
    One line is interesting here: "E/SurfaceFlinger( 74): hwcomposer module not found". Since the hwcomposer is supposed to initialize gralloc, it seems that gralloc is not loaded.

    Hi ,

    Thanks for the reply.
    Have a look in the below link. e2e.ti.com/.../264290

    With out hwcomposer gralloc messages are there.

    Hello,

    You could try to run the "strace" and "lsof" utilities on the library (inside "/system/lib/hw/gralloc.omap3.so").
    lsof will help you to see if this file is opened on your system, while strace will help you to find if a sytem call is addressed to the gralloc library.
    What do you need that for?

    Also, the log you are showing is from Angstrom running a 3.8 kernel, while Android from TI uses a 3.2 kernel; it is possible that they use a different version of gralloc, or one with more debug messages.
