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

Hi Rose, 

SYS/BIOS does not use the -heap section in the linker.cmd file.  After you set the heap size in the .cfg file (Rahul's sample code above), SYS/BIOS allocates that space within the program data section.  The -heap section should remain at 0. 

Let me know if you still encounter any problems.
