LAUNCHXL-F28379D: Memory Map File Error

Hi,

Pls share the linker command file. 

Also , can you try specifying the memory allocation for .ebss section as below (without the PAGE specifier)

.ebss            : >> RAMGS0 | RAMGS1 | RAMGS2 | RAMGS3

Best Regards

Siddharth

Satish,

Did you try changing the .ebss section to 

.ebss            : >> RAMGS0 | RAMGS1 | RAMGS2 | RAMGS3

Best Regards

Siddharth

Did you try changing the .ebss section to 

.ebss            : >> RAMGS0 | RAMGS1 | RAMGS2 | RAMGS3

Yes , Still the same issue persists. 

stack size taken  = 0x200

Heap Size taken = 0x100 

and used different iterations of Optimisation levels

please resolve this issue

Another option you can try is to combine the memory regions in the linker command file

   RAMGS0_3      : origin = 0x00C000, length = 0x004000 

and then use it in the SECTIONS like this

ebss            : > RAMGS0_3

Best Regards

Siddharth

Dear Sir, 

I tried the same as above, still the same issue persists. 

Please resolve this issue

Hi, 

Can you share the compilaton log and project?

Best Regards

Siddharth

Sir,

Please find the attached compilation log File .

Project Log.txt

Hi, 

If you read the log, you can find that the "..ebss" section size is 0x233e.  It needs a memory region which can accomodate this size. 

Can you share your updated linker command file with RAMGS0_3      : origin = 0x00C000, length = 0x004000 ?

Is there any other section that is allocated to RAMGS0_3?

Best Regards

Siddharth
