A simple example is a SMP environment, where two processors share all memory and all peripherals. To do this, change the settings for each processor (shown in the example in Figure 7.17):
Locate the
Memory_blockgroup for the connection.Expand the
Memory_blockgroup.Select
SharedRAMin the left pane.Define the region for the memory block:
Set the value of
Startto the start address for this memory block, for example 0x10000.Set the value of
Lengthin memory units for the memory block. For example, 0x1FFFF bytes for an ARM architecture-based processor.
Expand the
SharedRAMgroup.Select
Attributesin the left pane to display the list of attributes for this memory block. Figure 7.18 shows an example:Set up the attributes for the memory block:
Set the value of
Sharedto direct.Set the value of
Shared_idto 0x1.
You can use any integer value for the share ID in the range
0to65535. However, you must use the same value for each block that is sharing the same memory area. This enables RealView Debugger to identify which memory blocks relate to the same shared memory area.If this is a code region for both processors, then it is not advisable to use software breakpoints. To prevent software breakpoints being set in this memory area, set the
No_sw_bkptssetting to True (see Figure 7.18).
