stack_size redefined and undefined

Hello everyone,I have a problem need your guiding,the problem is shown below

Development environment:CCS3.3.82+xds560plus;

The chip is OMPAL138,but I only use the DSP CORE c6748,ARM part is not used;With DSP/BIOS SYSTEM bios_5.41.02.14;compiler is V6.1.11;

Building is well,but in the linking progress,the error is happened shown below

--------------------------------------------------------------------------------------------------------------------------------------------------------------

In the file dsplinker.cmd    stack is defined as:—stack  0x00000800;

In the .tcf file of BIOS system the  stack size is defined  0x0400;

Wish your guiding,thanks
