Unable to allocate Flash memory to store data of array of large size in TMS320f28377d

Hi,

I am trying to allocate an array of large size in the flash by using pragma directive and assigning a section "myvars1" in the .cmd file. While compiling, there are no errors, but I am not able to assign any value to it , the variable shows 65535 value and any change to that value isn't happening. I am able to assign in a similar way to RAM but not to Flash. What might be the reason for that? Can we not assign Flash for storing data? Below is my cmd file. Any help on this would be appreciated. Thanks.
