How can I revise the param of -heap to 0x1000 from 0x0 with linker.cmd which created automatically by XDC

Hi,

I am working with OMAPL138LCDK. And I have created a custom platform for my own omapl138 accodring to:

http://rtsc.eclipse.org/docs-tip/Demo_of_the_RTSC_Platform_Wizard_in_CCSv4

The platform setting as following:

Then I create ccs project with 'Typical' example of SYSBIOS that the configuration project is a separate project from the app project.  The linker.cmd built from the configuration project has the parameter  as following:

--args 0x0
-heap 0x0
-stack 0x2000

But my program has to using the malloc() which need heap was not zero.I have tried to revise directoryly linker.cmd  or source of app.cfg.  and got the same result that the heap was also zero instead of my hope value.

The version I am working with as follow:

CCS:5.1.1.00031 

XDC:3_23_01_43

SYS/BIOS:bios_6_33_01_25

Compiler:Ti V7.3.1

How can I get a none zero value for the heap for my program? Would please give me some advice on it.

Thanks!

Best regards.
