Hello, we are using the HalCoGen RM48L952ZWT and I am currently running out of internal RAM to execute the code and data. I need to put these code into external SDRAM.
I follow the instructions to define and put the code into external SDRAM. But when I compile the code, I received these errors below:
'Building target: BiolasePFB_ProductionBoard.out'
'Invoking: ARM Linker'
'Flags: -mv7R4 --code_state=32 --float_support=VFPv3D16 --abi=eabi -me -g --gcc --display_error_number --diag_warning=225 --diag_wrap=off --enum_type=packed --printf_support=nofloat -z -m"BiolasePFB_ProductionBoard.map" --heap_size=0x800 --stack_size=0x800 -i"C:/ti/ccsv6/tools/compiler/arm_5.1.6/lib" -i"C:/ti/ccsv6/tools/compiler/arm_5.1.6/include" --reread_libs --warn_sections --display_error_number --diag_wrap=off --xml_link_info="BiolasePFB_ProductionBoard_linkInfo.xml" --rom_model'

Below is how I define my main() code to be executed in external SDRAM based on the instructions:
In sys_startup.c file, I have:
/* USER CODE BEGIN (1) */
#include "emif.h"
/* USER CODE END */
/* USER CODE BEGIN (2) */
extern uint32 MainLoadStart;
extern uint32 MainLoadEnd;
extern uint32 MainSize;
extern uint32 MainStartAddr;
extern uint32 MainEndAddr;
/* USER CODE END */
/* USER CODE BEGIN (26) */
emif_SDRAMInit();
int i;
uint32 size=(uint32)&MainSize;
for(i=0;i<size;i++)
{
((char *)&MainStartAddr)[i] =((char *)&MainLoadStart)[i];
}
/* USER CODE END */
/* call the application */
/*SAFETYMCUSW 296 S MR:8.6 <APPROVED> "Startup code(library functions at block scope)" */
/*SAFETYMCUSW 326 S MR:8.2 <APPROVED> "Startup code(Declaration for main in library)" */
/*SAFETYMCUSW 60 D MR:8.8 <APPROVED> "Startup code(Declaration for main in library;Only doing an extern for the same)" */
#pragma SET_CODE_SECTION(".main_section")
main();
#pragma SET_CODE_SECTION()
/* USER CODE BEGIN (76) */
/* USER CODE END */

exit(0);
Please help and let me know how to compile and build these code without linking, or compiling errors.
Thanks for your help!
