Ok, ur not a C programmer yet. Try this way:

if((fileid = fopen(
"C:\\CCStudio_v3.1\\boards\\pep5416\\examples\\test\\test", "r" )) =NULL )

Hi jeff
thanks. Well I found the error. I actually stored the file in the main folder. I need to store it in the debug folder to access it. I am able to access the data now.
Thanks

Hi Everyone
I am not able to allocate the memory properly in C5416. I am not able to understand which part should be allocated IDATA, IPROG, DARAM, SARAM...
I need to use the external memory and hence i am using the SARAM and DARAM. I have allocated the memory but I am getting an error as
Trouble Running Target CPU.
When I click on Go Main after loading the file, the cursor goes to some random location in my code. Its not going to the Main(). And its giving the above error. I think its due to unproper allocation of memory. I am attaching my code. I am working on TI C5416 simulator. If its possible for you to see and suggest something on the memory allocation (in cdb file System -> MEM -> right click properties), kindly do that.
Thanking You

Dear Megha Daga,

there is one book "digital signal processing" by avatar singh which is specially written for TMS320C5416.

When you are using extended memory feature in C5416 processor, you should change some register values in GEL file. As well as you have to change the lib file to rts_ext.lib.
I did my porting work of AMR Decoder on this processor using extended memory. for further clarifications send me mail stating clear cut problem.
