Fail to run modutest.out drv_isif on dm368

Hi all:

We have a problem to run moduletest.out drv_isif on DM368 , when we try

   $./moduletest.out drv_isif

in function DRV_vpssInit(in file Drv_vpss.c):

    DRV_SyncRst(47, 0, 0); runs OK

    but DRV_SyncRst(47, 0, 3); will fail

    we got OSA_ERROR("pMem_map Fail!! \n"); because of preceded `mmap` syscall.

anybody give me some suggestion

 

 

Thanks and Regards
