[ft-devel] porting freetype to Texas DSP C55x

[Peter M]

I have successfully compiled the freetype 2.1.8 engine on Code Composer 2.21 but I expiriance some memory problems.

The problem seems to be with the malloc, free, realloc  functions.To solve the issues there must be used the TI specific

functions:

 

-----------------------------------------------------------------------------------------------------------------------------------------

Syntax:                   addr = MEM_alloc(segid, size, align);

 

Parameters:            Int            segid;      /* memory segment identifier */ 

            Uns             size;        /* block size in MADUs */ 

            Uns             align;       /* block alignment */

 

Return Value:         Void        *addr;      /* address of allocated block of memory */

-----------------------------------------------------------------------------------------------------------------------------------------

Syntax:                   status = MEM_free(segid, addr, size);

 

Parameters:            Int            segid;      /* memory segment identifier */ 

            Ptr               addr;       /* block address pointer */ 

            Uns             size;        /* block length in MADUs*/

 

Return Value:         Bool         status;     /* TRUE if successful */

-----------------------------------------------------------------------------------------------------------------------------------------

Syntax:                   MEM_redefine(segid, base, length);

Parameters:            Int            segid;      /* segment to redefine */ 

            Ptr               base;       /* base address of new block */ 

            Uns             length;     /* length (in MADUs) of new block */

 

Return Value:         Void

-----------------------------------------------------------------------------------------------------------------------------------------

 

 

My questions are:

- Doze someone use freetype on a Texas c55x platform?

- How match RAM dose it use?

- How to rewrite or change the memory object to make it work?

 

 

Tanks in advance
