Compile issue when I transfer project from CCS4 to CCS6

hi,

Before the project compile good with CCS4, when I switch to CC6. Have the below issue:

"xxx\myF2811.cmd", line 114: error: program will not fit into available memory.  placement with alignment/blocking fails for section ".text" size 0x8fb7 page 0.  Available memory ranges:
   FLASHE       size: 0x8000       unused: 0x8000       max hole: 0x8000   
error: errors encountered during linking;

Seems that source code size is bigger than the arranged segment size?

Best regards,

Kent
