hi all,

i am trying to bringup display on pandaboard with ICS , but while booting i got following errors:

PVR: Installing MISR with cookie c0886170

PVR:  Intalling device LISR SGX ISR on IRQ 53 with cookie eadda000
PVR:  OSUnMapPhysToLin: unmapping 65535 bytes from f0b20000

PVR:  SysFinalise: Version string: SGX revision =1.2.0

PVR_K: (FAIL) SGXInit: Incompatible driver DDK revision (550175)/device DDK revision (279068).

PVR_K: (Error): PVRSRVFinaliseSystem: Failed PVRSRVdevInitCompatCheck call (device index: 0) [449, drivers/gpu/pvr/pvrsrv.c]

PVR_K:(Error): BridgedDispatchKM: Initialisation failed. Driver unusable.  [4811, drivers/gpu/pvr/bridged_pvr_bridge.c]

please suggest me how to solve this problem..

    The version of the IMGTEC binaries you are using does not match the kernel version of the PVR driver.

    Try to find the right IMGTEC binaries or use a different branch where the PVRVERSION_BUILD in

    ./drivers/gpu/pvr/pvrversion.h matches the user-space driver's version.

    Thanks for giving replay..

    ->   After booting kernel on pandaboard i checked in proc entry for pvr version:

                   cat /proc/pvr/version:

                   it shows:   version is 1.2.0

            In .drivers/gpu/pvr/pvrversion.h ->file  version is declared as 1.8 in 3.0.8 kernel.

             but it continuously priting previously sended errors.

    -> But HDMI display is working on pandaboard with linaro kernel.

         i checked that version also in proc/pvr/version:

           it shows same version : 1.2.0

           In drivers/gpu/pvr/pvrverion.h -> version is declared as 1.7 in linaro kernel

    -> ICS-4.0 graphics support libraris i downloaded and copied in to rootfile system -> system/vendor/lib/

         so it continuously printing previosly sended errors.   

        Please suggest me how to solve that error..

    4. compile your new kernel and mv it to <ANDROID_PATH>/devices/ti/panda

    5. compile Android and enjoy it
