Problems and doubts with SpO2 program + NAND Flash memory

Hi everybody,

I have a 5515evm with a SpO2 daughter card running in CCS4. I'm using the demo program for SpO2 (I downloaded it from http://code.google.com/p/c5505-ezdsp/). 

The problem is that I want to storage data from the daughter card to NAND Flash, and I've tried it with the Chip Support Library and without it, and I'm having a lot of errors in the problem when I want to initialize the NAN Flash memory. I've followed the examples from CSL and examples from  the CCS4   instalation directory: ...\Texas Instruments\ccsv4\emulation\boards\evm5515_v1\tests\nandflash.

I initializate the NAND in this way:

SpO2_Status inicializar_NAND()
{

//*(ioport volatile unsigned *)0x1C04=0x10; //PSRCR
	SYS_PRCNTR   =0x10; 
	/* reset Emif Module */
	//*(ioport volatile unsigned *)0x1C05=0x2; //PRCR

    wait(500);
	EMIF_AWCCR1 = 0x0080; 
	EMIF_AWCCR2  = 0x00E4;

and in this sentence:

EMIF_AWCCR1 = 0x0080; 

I find this error:

C55xx: Can't Single Step Target Program: Error 0x20000022/-2130 Severe Error during: Memory, Execution,  Cannot access memory address at 0x00000800  

I'm not able to initializate the NAND Flash neither registers nor CSL.

What's wrong?
