Not sure if they will apply straight on your kernel You will have to pull in these two patches ~
Patch 1: Enabling oprofile in zoom2_defconfig * Disabling oprofile ARMv7 by default * Currently we are using ARMv6 target http://git.omapzoom.org/?p=kernel/omap.git;a=commitdiff_plain;h=3b264cae0c4d080cbcb0a74e27a0b1e4f2379b17 Patch 2: ARM: OMAP: gptimer based event monitor driver for oprofile <http://git.omapzoom.org/?p=kernel/omap.git;a=commit;h=3b264cae0c4d080cbcb0a74e27a0b1e4f2379b17> http://git.omapzoom.org/?p=kernel/omap.git;a=commitdiff_plain;h=e45e6b647c156c032924ad11b4f99c8132da4363 Thanks, Akash On Fri, Apr 16, 2010 at 5:49 AM, Ashu <ashutosh.deshmukh2...@gmail.com>wrote: > Hi All, > I am using Android 1.6 on OMAP3430 Board.
