Reading Linker script variables in C source code

Hi Every one!! 

 

 

I am using the NIOS II IDE 6.1simulator. 

I want to read the linker defines in C.(using variables from generate.x file and access them in the C source code) 

 

This is the format I tried... 

printf("\n DDR SDRAM 0 : %08X", &__alt_mem_ddr_sdram); 

 

I tried to execute the code on the simulator.But the following error is encountered for all the variables in the logical sections of RAM.(.text,.rodata,rwdata etc..) 

Eg. 

Unable to reach &__alt_mem_ddr_sdram(at 0x00000000) from the global pointer (at 0x0401a8a4) because the offset (-67217572) is out of the allowed range, -32678 to 32767.  

 

Let me also know if the format is correct.  

Awaiting your response. 

 

Regards, 

samira
