Hi,
I am running camera capture application (based on omap iss, v4l2,
videobuf2-dma-contig, x11, gles2) on customized OMAP5 board with 3.8 kernel
and rootfs based on GLSDK 6.04.00.02. However within 12 to 30 minutes it
crashes with following trace.
I have reverted Link 1 patch from omap_gem.c and integrated link 2 patch to
fix another crash I was observing
Link1:
http://git.omapzoom.org/?p=kernel/omap.git;a=commitdiff;h=f968e920452aa3061fb1dfff1a55a55f8af60dde;hp=1bca805f90dc31eac5a2093074cf70fe1b806f55
Link2:
http://omapzoom.org/?p=kernel/omap.git;a=commitdiff;h=0f88f7ca8283f9407a17f150968c6fc1a980231c;hp=0421a5efd6e44bb29e3abe2dc80b4b2564083df9
Could anyone give some inputs/suggestion to understand and fix this crash?
How should I start debugging it?
Regards & Thanks,
Vikash
