About h264venc-r demo On DM365

hi, all:

         I meet problem when using h264venc-r demo on DM365. My boot cmdline is "mem=64M console=ttyS0,115200n8 noinitrd rw ip=192.168.42.101 root=/dev/nfs nfsroot=192.168.42.65:/home/fx/project/dm365/filesys dm365_imp.oper_mode=0".

         And use default param in demo to insmod cmem.ko: "insmod cmemk.ko phys_start=0x86500000 phys_end=0x88000000 pools=2x2457600,1x1843200,1x4297168,1x100000,1x400000,1x300000,1x100000,3x100000,1x100000,2x100000,1x100000,1x100000,1x100000,1x100000,1x100000,1x100000,1x3550000,6x180,3x38016 allowOverlap=1 phys_start_1=0x00001000 phys_end_1=0x00008000 pools_1=1x28672"

        When I run the program 'h264venc-r', the kernel panic and wrong information is following:

root@./h264venc-r
ADDRSPACE Protocol Registration Success
MEMTCMUnable to handle kernel paging request at virtual address fbc40018

The program have stop the last line "Reading Input Frame - Input Frame Read Done",  and the OS have no response, must to reset.

How can I run the demo? What did cause the problem?

Thanks a lot!

    Thanks， I know what cause to this problem. When I used modules in directory of /dvsdk/dm365_codecs_01_00_06/packages/ti/sdo/codecs/h264enc/apps/client/build/arm926, and run h264venc-r，it caused to kernel panic；and when using modules in the directory of /dvsdk/linuxutils_2_24_02/packages/ti/sdo/linuxutils. It can run successfully. And I contrast the modules of two directorys, found modules have different size and informations;

    Using irqk.ko, insmod two modules separatly, cat /proc/modules, the informations is following:

    linuxutils modules sizes:8486 Bytes

    cat /proc/modules:

    irqk  8552 0 - Live 0xbf056000

    dm365_codecs_01_00_06/packages/ti/sdo/codecs/h264enc/apps/client/build/arm926 modules sizes: 8606 Bytes

    cat /proc/modules:

    irqk  8584 0 - Live 0xbf056000

    Have two modules difference version?

    I suspect that the irqk.ko from the /dvsdk/dm365_codecs_01_00_06/packages/ti/sdo/codecs/h264enc/apps/client/build/arm926 modules directory is from a LinuxUtils version 2.25 and is therefore incompatible with an app linked with the LinuxUtils 2.24.02 package.  The ioctl() command codes changed in LinuxUtils 2.25, so when using the irqk.ko module from LinuxUtils 2.25 you need to make sure the application links with the LinuxUtils 2.25 package (since the ioctl() commands used by the LinuxUtils 2.24.02 package would not be recognized by the LinuxUtils 2.25 irqk.ko module).

    I suspect this because your crash dump ends with a listing from ioctl() indicating "[irqk]".

    Regards,
