Often, an application must have an empty uninitialized memory area to be used for temporary storage, for example, a heap or a stack. It is easiest to achieve this at link time. You must create a block with a specified size and then place it in a memory.

In the linker configuration file, it can look like this:

define block TempStorage with size = 0x1000, alignment = 4 { };
place in RAM { block TempStorage };

To retrieve the start of the allocated memory from the application, the source code could look like this:

/* Define a section for temporary storage. */
#pragma section = "TempStorage"
char *GetTempStorageStartAddress()
{
  /* Return start address of section TempStorage. */
  return __section_begin("TempStorage");
}
