Some quick feedback - note that Memory_getPhysicalAddress() is _not_ a supported API. (And in fact has been deprecated in recent releases of Codec Engine.) I know the demos use it, they shouldn't have been. Supported APIs are documented in the CE API Reference Guide.
_Instead_, please use the more powerful, and _supported_ API, Memory_getBufferPhysicalAddress(). For more details, see the "Upgrade Information" section of the Codec Engine 2.00 release notes: https://www-a.ti.com/downloads/sds_support/targetcontent/CE/ce_2_00/code c_engine_2_00/release_notes_codec_engine_2_00.html#Upgrade_Info Chris > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] > ] On Behalf Of Schoenemann, Nikolaus > Sent: Thursday, January 31, 2008 7:27 AM > To: Jitendra; [email protected] > Subject: RE: Video display driver > > Jitendra, > > Try 'Memory_getPhysicalAddress(ptr virtualAddress)' defined in <ce > install directory>/packages/ti/sdo/ce/osal/Memory.h > > Cheers, > > Niko > > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On > Behalf Of Jitendra > Sent: Thursday, January 31, 2008 1:13 PM > To: [email protected] > Subject: Video display driver > > Hello all, > I am working on video display driver i.e. davincifb and using Davinci > based custom board > >From display application I am using mmap for buffer > allocation and mmap > returns virtual address. > I need physical address. > Can anyone pls help me how to get physical address? > > Waiting for your reply. > > Thanks in advance. > > Regards, > Jitendra > > -- > eInfochips Business Disclaimer: > > This message may contain confidential, proprietary or legally > Privileged > information.
