I am new to C5535, and I have this development board eZdsp C5535 kit. I have tried the basic program which was mentioned in the "Quick Start Guide" which I got along with the kit. It worked perfectly. Now, when I try to write a simple code by myself it shows error due to some linking problem. I went through lot of these forums and nothing were of any help to me.
Here is the basic code which I tried to build in CCS v4.2.2:
#include "stdio.h"
#include "ezdsp5535.h"
#include "ezdsp5535_led.h"
#include "ezdsp5535_gpio.h"
void main() {
EZDSP5535_init();
EZDSP5535_LED_init();
printf("Last Line");
}
I have the "lnkx.cmd" present in the project directory where this source file is present. I also have " ezdsp5535bsl.lib" present in the same directory. In the "Include Options", I have added the directory where all the following files are present. Below is the snapshot:
By default, there is another include present: C:\Program Files (x86)\Texas Instruments\ccsv4\tools\compiler\c5500\include
Now, when I build this project, it gives the following results:
**** Build of configuration Debug for project led ****

I have provided all the details. If anybody here could help me to solve this problem, it would be really good.
Thanks in Advance!
