Hello, I am working on TI EVM Davinci . I was trying to make video display application working. For that I made my own folder cpoied video_display folder into mine . then I need to change the Makefile in the Video_display folder. there i found XDC path , I am not able to understand what path i should provide there for DMAI. I need to know when it said that dmai_Install_dir/ packages which are thoose pacake laocated and other packages in the make file. so that I can link them in the make file ]

XDCPATHS variable normally points to all directories where "packages" subdirectories are found for your project.  When building your project, the build system will try to find all necessary packages within the directories pointed to by XDCPATHS

I am not sure if I understand your question, but one normally uses the -I prefix to specify include directories which contain the project's header files.  For example

   -I/home/user/workdfir/lsp/ti-davinci/include

Let me know if this helps or if you are after something else

Here is my application code file - montavista 5 's PSP 's IPIPE example code "ipipe-720p-example.c"

/*************************************************************************

 * Additional HEADER FILES

 */

/* Kernel header file, prefix path comes from makefile */

#include <media/davinci/davinci_vpfe.h>

#include <media/davinci/ccdc_dm355.h>

#include <ccdc_dm355.h>

#include "ipipe_example.h"

#include <asm/arch/dm355_ipipe.h>

#include "ipipe_config.h"

#include "mt9t001_capture.h"

#include "display.h"

/*******************************************************************************

And they have given the following MAKE file,

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

# Makefile for IPIPE applications

CC = $(CROSS_COMPILE)gcc

clean:

rm -f *.o *~ ipipe_vga_example ipipe_480p_example ipipe_720p_example ipipe_rsz_example ipipe_1080i_example

Thank you very much , Now i think I can do this.

I will get back to u if I make struck in such silly error :)
