Regarding the End of Line Expected errors for pragma definition in coldfire

Hi,

  I want to relocate a function to a RAM location. I referred AN4329 and used the  Method 1 but I am getting compilation errors as end of line expected for all the three pragama statements. . I did try another method as defined below under Method 2, I am gettign errors for end of line expected along with illegal or unsupported attribute

Please suggest what is the best or any alternative to relocate a function to a RAM location

Method 1

/////defined in .c file

#pragma define_section mySectionInRAM “.myCodeInRAM” far_absolute RX
#pragma section mySectionInRAM begin

void function1(void);

void function1(void)

{

--

 

}

#pragma section mySectionInRAM end

 

Method 2

#pragma section RX “.myCodeInRAM” data_mode=far_abs
//#pragma section mySectionInRAM begin

__declspec(section ".myCodeInRAM") void function1(void);

__declspec(section ".myCodeInRAM") void function1(void)

{

}

 

Also my linker file where I created new section myCodeInRAM

 

#/*
# * File: flash.dld
# * Purpose: Linker file for M5475EVB and M5485EVB
# *
# * Notes: Creates a Flash bootable image
# */

Hi

Please try to change the lcf file with memory size.

For example:
