How to put unrefered variable in the image

Hi, everybogy

I created a simple example project consist of only one source code file main.c, within Keil MDK 3.24 Eval as below.

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

#include <lpc23xx.h>

unsigned int variable0 __attribute__((section("sec_data"), used)) = 0x55AA55AA;

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

int main (void)
{ unsigned int i;

while (1) { i++; }
}

// End of File

And when I compiled and linked the example using a scatter loading descrption file, one warning feedback produced by the linker read like this.

"Prj1.sct(14): warning: L6329W: Pattern *.o(sec_data) only matches removed unused sections."

The warning message above showed that the section sec_data had been removed by linker for the reason of no refered by the source code explicitly.

The scatter description file causing the warning read as below

LR_IROM1 0x00000000 0x00080000
{

ER_IROM1 0x00000000 0x00080000

{

*.o (RESET, +First)

*(InRoot$$Sections)

.ANY (+RO)

}

TABLE 0x40000000 0x20

{

*.o(sec_data)

}

RW_IRAM1 0x40001000 0x00001000

{

.ANY (+RW +ZI)

}

}


How can I restain the unrefered variable variable0 in the last image?
Please give your hand!
