Hi all, we are using our own custom made board with DM6446. I have written a camera capture application which captures images encodes it in H264, decodes it & then display it on fb. It runs smoothly for some time & then crashes .
How do I debug this crash dump so that i can find the source of the problem. ortp-m, *pte=00000000essage-get_pictu, *ppte=00000000re_buffer_size 1 07 ortp-messageInternal error: Oops: 7 [#1] Modules linked in: dsplinkk cmemk CPU: 0 Not tainted (2.6.23-davinci1 #219) PC is at SYNC_WaitSEM+0x1d0/0x260 [dsplinkk] LR is at __atomic_notifier_call_chain+0x1c/0x24 pc : [<bf00d680>] lr : [<c004959c>] psr: 50000013 sp : c1975dd0 ip : 00000000 fp : c1975e44 r10: c0038e14 r9 : 00008000 r8 : c7930008 r7 : c1974000 r6 : c1975de8 r5 : c7930000 r4 : c1975de0 r3 : 00000001 r2 : c04bb900 r1 : 00000002 r0 : c04bb900 Flags: nZcV IRQs on FIQs on Mode SVC_32 ISA ARM Segment user Control: 0005317f Table: 81794000 DAC: 00000015 Process linphonec (pid: 1118, stack limit = 0xc1974260) Stack: (0xc1975dd0 to 0xc1976000) 5dc0: 00000000 c04bb900 c0038e14 00000000 5de0: 00000000 00000000 00000001 c04bb900 c0038e14 c7930008 c7930008 c0038edc 5e00: 60000013 ffffffff 00000000 bf02211c 00000000 c7932008 c1975e44 00008000 5e20: c15174c0 bf02211c c67526e0 bf02210c 00000000 00000000 c1975e7c c1975e48 5e40: bf00c4d4 bf00d4c0 bf00b8d8 ffffffff c1975e8c c1975e8c 00000000 00008000 5e60: 00007302 c002861c c1974000 00900036 c1975eac c1975e80 bf00c714 bf00c394 5e80: 00000000 00000000 c1975f0c 00000000 c0027ab4 c1975f00 00008000 00008000 5ea0: c1975efc c1975eb0 bf008930 bf00c5d8 40020000 c6687288 00000000 40020000 5ec0: 4002b000 40020000 c748d23c c1975f1c c1975f0c c1975ee0 c006e18c 43f60170 5ee0: 00000000 43f60170 00000000 00007302 c1975f34 c1975f00 bf008138 bf0081c8 5f00: 00008000 00000000 40020480 00008200 001eff10 00008000 c75758a0 ffffffe7 5f20: 43f60170 00000011 c1975f54 c1975f38 c008b490 bf0080b8 c1975f84 c75758a0 5f40: 43f60170 00000000 c1975f7c c1975f58 c008b72c c008b42c 00008680 c6752714 5f60: fffffff7 43f60170 00007302 c75758a0 c1975fa4 c1975f80 c008b790 c008b4b0 5f80: c0073d9c 00000001 001f02b0 43f61000 00215d70 00000036 00000000 c1975fa8 5fa0: c0027e20 c008b75c 001f02b0 43f61000 00000011 00007302 43f60170 00213e60 5fc0: 001f02b0 43f61000 00215d70 00000108 00215d34 000005a0 00000000 43f6016c 5fe0: 001d6024 43f60110 000221e4 401d2294 80000010 00000011 020030fe e2200000 Backtrace: [<bf00d4b0>] (SYNC_WaitSEM+0x0/0x260 [dsplinkk]) from [<bf00c4d4>] (UEVENT_AddBufByPid+0x150/0x17c [dsplinkk]) [<bf00c384>] (UEVENT_AddBufByPid+0x0/0x17c [dsplinkk]) from [<bf00c714>] (NOTIFY_KnlFinalize+0x14c/0x16c [dsplinkk]) [<bf00c5c8>] (NOTIFY_KnlFinalize+0x0/0x16c [dsplinkk]) from [<bf008930>] (DRV_CallAPI+0x778/0x8f0 [dsplinkk]) r6:00008000 r5:00008000 r4:c1975f00 [<bf0081b8>] (DRV_CallAPI+0x0/0x8f0 [dsplinkk]) from [<bf008138>] (DRV_Ioctl+0x90/0x110 [dsplinkk]) r7:00007302 r6:00000000 r5:43f60170 r4:00000000 [<bf0080a8>] (DRV_Ioctl+0x0/0x110 [dsplinkk]) from [<c008b490>] (do_ioctl+0x74/0x84) r7:00000011 r6:43f60170 r5:ffffffe7 r4:c75758a0 [<c008b41c>] (do_ioctl+0x0/0x84) from [<c008b72c>] (vfs_ioctl+0x28c/0x2ac) r6:00000000 r5:43f60170 r4:c75758a0 [<c008b4a0>] (vfs_ioctl+0x0/0x2ac) from [<c008b790>] (sys_ioctl+0x44/0x68) r7:c75758a0 r6:00007302 r5:43f60170 r4:fffffff7 [<c008b74c>] (sys_ioctl+0x0/0x68) from [<c0027e20>] (ret_fast_syscall+0x0/0x2c) r7:00000036 r6:00215d70 r5:43f61000 r4:001f02b0 Code: eb410c34 e597200c e3a03001 e5823000 (e5953010) -- Thanks & regards yuvraj pasi
