Shared memory in Concerto

Hi,

I created a project based on Sys/Bios/Generic Examples/Memory example with platform ti.platforms.concertoC28:F28M35M52C1 (CCS 5.1.1, SYS/BIOS 6.33.3.33).
Is it possible to use in the project S07SHRAM memory, that defined in   F28M35M52C1.cmd file?  ( S07SHRAM    : origin = 0xC000,   length = 0x8000)
 when I change the following lines in F28M35M52C1.cmd:
   .stack      : >  M01SARAM | L03SARAM PAGE = 1
    .ebss       : > M01SARAM | L03SARAM PAGE = 1
  to :
 .stack      : > S07SHRAM | M01SARAM | L03SARAM PAGE = 1
    .ebss       : >S07SHRAM | M01SARAM | L03SARAM PAGE = 1

project doesn't run.

Could you explain what is the problem here? Why i can not put stack or ebss on the shared memory?

Thanks, Sabina
