Can i see the Xgate memory map?

[rahulkrishna]

Hi,

Like global memory map which i can see in the .hex file and the local memory map in the s19 files. Is it possible for me to see only the xgate code and data variables in terms of xgate address not global or local addresses? This will help to see the variables which are shared are misaligned. One related question is why S12x does not follow any alignment for other varaibles why does it not generate bus error for misaligned data?

Hi Rahul,

I don't understand what is the .hex, local memory and .s19 files.

The map file generated should contains all info including Xgate code and data.

Is there a way to generate the info for S12 or Xgate only ?

      The map file is generated by the linker according to the project.

      It contains all project information for S12 and Xgate cores.

By default there is a specific section for Shared Date (SHARED_DATA) which can be used by S12 and Xgate.

I've created an example containing 4 variables:

SECTION: "SHARED_DATA"

  val_1 val_2 val_3 displayValue

MODULE:

-- XGglobals.cxgate.o --

- PROCEDURES:

- VARIABLES:

	val_1	2000	2	2	1  SHARED_DATA
	val_2	2002	2	2	3  SHARED_DATA

MODULE:

-- CPU12Globals.c.o --

- PROCEDURES:

- VARIABLES:

	val_3	2004	2	2	2  SHARED_DATA
	displayValue	2006	1	1	3  SHARED_DATA

Have a great day,
Pascal
