C2000: Linker Command File

Mike Launch

Other Parts Discussed in Thread: TMS320F28027

Hello All,

I am just getting started with TI-RTOS with the help of the TI videos. When building the basic example, my code does not compile giving me the following error:

"#10099-D program will not fit into available memory. run placement with alignment/blocking fails for section ".ebss" size 0x1458 page 1. Available memory ranges: TMS320F28027.cmd /TM4C_BIOS_New line 109 C/C++ Problem"

I am using the development board with the TMS320F28027. Here is the linker command file. What am I doing wrong? The following linker command was automatically generated when creating a minimial TI-RTOS CCS project. The offending line seems to be " .ebss : > M01SARAM | L0SARAM PAGE = 1"

My main.c is rather trivial:

#include <xdc/std.h>
#include <xdc/runtime/System.h>
#include <ti/sysbios/BIOS.h>
#include <ti/sysbios/knl/Task.h>

/*

 */
Void taskFxn(UArg a0, UArg a1)
{
    System_printf("enter taskFxn()\n");
    Task_sleep(10);
    System_printf("exit taskFxn()\n");
}


Int main()
{ 
    /*
     * use ROV->SysMin to view the characters in the circular buffer
     */
    System_printf("enter main()\n");	
    BIOS_start();    /* does not return */
    return(0);
