How do I set memory access size?

Memory access is set to the default for the processor in RealView Debugger. For ARM processors, this is byte-size. You can change the Access_size setting in the Connection Properties window to define a different access size. You must also define the block of memory to which it applies. The following example shows you how to set up a small memory block, designated as RAM with word-size access:

1.   Select Connection Properties from the Code window Target menu to display the Connection Properties window.

2.   Expand the CONNECTION group (or BOARD group if you are using a specific.bcd definition) for your target. This example uses a custom RealView ICE connection:

3.   Expand Advanced_Information until it looks like this:

4. Right-click on Default under Memory_block and select Make Copy…to set up a custom memory block

5. Enter the name of the memory block when you are prompted, for example, Access_new.

6. Click Create on the Prompt dialog to create the new group of settings:

7. Click on Access_new to see its settings in the right pane:

8. Set Start to 0x0 and Length to 0x1000

9. Click on Attributes to display settings including Access_size in the right pane:

Access_size is set to 0, that is, memory access size is at the default for the processor (byte-size for ARM processors).

10. Right-click on Access_size and select 4 to set the Access size to 4 bytes.

11. Select Save and Close from the File menu.

12. Connect to the target.

13. Select Memory Map Tab from the Code window View menu to see the memory block that you set up for your processor

14. Right-click on the new memory and select Properties from the context menu to see its attributes:
