Sample Application - LED program to boot from C5535 EEProm

kranthi kumar

Hi everyone, Am facing similar problem.

Actually am trying sample LED code to boot from c5535 EEPROM. I now the procedure to convert the .out file to .bin.

Here i need is to include initialization part to sample lcd code. Can you please provide the total sample led program which having initialization to boot from EEPROM.

Thanks,

Kranthi.

Kranthi,

The other post is not entirely related to your issue. I have split the thread to help others follow your post better.

In addition, to get a little bit more information. Are you using the EZDSP C5535?

Regards,

_Nic

}

Attached is a file I used to program the PLL to toggle the XF output. You can use it as an example. The key is the top portion to program the PLL. You can refer to GEL for more PLL frequnecy settings. Also, since you have a working program already, your must have peripheral clock enabled.

Hope this help.

Regards.

Hi Steve Tsang,

Thanks.

I have build sample led test as followed

#include "stdio.h"
#include "ezdsp5535.h"

#define PCGCR1 0x1c02

#define PCGCR2 0x1c03

#define CCR2 0x1c1f

}

Able to run the .out file but unable to boot from EEPROM, Is the above code need any changes please tell me.

Thanks and regards,

Kranthi.

Can you boot from EEPROM with my code?

Regards.

0 Steve Tsang over 12 years ago in reply to Steve Tsang

TI__Mastermind 23785 points

I can't compile your code without the ezdsp5535.h. You should start with the code I provided. I tried on c5535ezdsp to blink XF LED via SPI EEPROM. Once you get it to work, you should be able to debug your code. Make sure SW3 bit 4 is set to "ON" position to use on board SPI EEPROM. Bit 4 is the far right from the white dot pin 1 indicator and "ON" is the opposite side of white dot.

Hope this help.

Regards.

Am working with your program 7167.main.c, here am unable to compile as it was saying

could not open source file "std.h" ledblink led.c

I don't have std.h file.

Kranthi.

0 Steve Tsang over 12 years ago in reply to kranthi kumar

TI__Mastermind 23785 points

Replace it with tistdtypes.h for CCS4 and up. Let me know.

I wrote std.h library as given below.

/*****************************************************************************/
//#ifndef _STD_H_
#define _STD_H_

/* 7.18.1.1 Exact-width integer types */

#if defined(__MSP430__) || defined(__TMS320C55X_PLUS_BYTE__)
typedef signed char int8;
typedef unsigned char uint8;
typedef int int16;
typedef unsigned int uint16;
typedef long int32;
typedef unsigned long uint32;
#else
typedef int int16;
typedef unsigned int uint16;
typedef long int32;
typedef unsigned long uint32;
#endif

typedef long long int40;
typedef unsigned long long uint40;

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

Now i cleared the source file issue, and there is n error but still am unable to built the .out file.

Here in my consoul its showing as given below

Am facing error there as "expecting a statement"

That's is for the for loop. Actually, both for statements are to have some time in between the XF on/off so human eyes can see the led on/off.
