static BOOL imx_vpu_load(void)

{

IMX_VPU_LOG("VPU init instance counter: %lu", vpu_init_inst_counter);

if (vpu_init_inst_counter != 0)

{

++vpu_init_inst_counter;

return TRUE;

}

else

{

++vpu_init_inst_counter;

return TRUE;

}

else

{

IMX_VPU_ERROR("loading VPU failed"); //logs show reach to here

return FALSE;

}

}

}

logs:

imxvpuapi imxvpuapi_vpulib.c(312):imx_vpu_load: VPU init instance counter: 0

imxvpuapi imxvpuapi_vpulib.c(321):imx_vpu_load: libimxvpuapi version 0.10.3 vpulib backend
imxvpuapi imxvpuapi_vpulib.c(331):imx_vpu_load: loading VPU failed

what's possibilities to get this kind of error ? Is the library libvpu.so.X trying to access files which are limited to the calling process?
