Working with Hardware Diagnostics Window

The Hardware Diagnostics window lets you run a series of diagnostic tests that determine if the basic hardware is functional.

These tests include:

• Memory read/write - Makes a read / write access to memory in order to read or write a byte, word (2 bytes), and long word (4 bytes) to / from memory.
• Scope loop - Makes read and write accesses to memory in a loop at target address. The the loop speed settings determine the time between accesses. The loop can only be stopped by cancelling the test.
• Memory tests - Requires you to set the access size and target address from the access settings group and the settings present in the Memory Tests group.

On the Eclipse IDE, the hardware diagnostics feature runs like a target task.

To create a hardware diagnostic target task:

1. Click Window > Show View > Other.

   The Show View dialog box appears.

2. Expand the Debug group and select Target Tasks.
3. Click OK.
4. Click Add New Task from the Target Tasks view t oolbar to create a new target task.

   The Create New Target Task wizard appears.

5. In the Task Name text box, enter the name of the target task.
6. From the Run Configuration drop-down list, select a configuration.
   Note: Select Active Debug Context from the Run Configuration drop-down list, if you want to use hardware diagnostics over an active debugger session, else select any of the specified debug context from the list.
7. From the Task Type drop-down list, select Hardware Diagnostic.
8. Click Finish.

   The Hardware Diagnostics Action window appears.

The Hardware Diagnostics Action window includes the following groups:

• Action Type - Used to set various action types. The options you select in this group enables the options in the other groups of the window.
• Memory Access - Configures diagnostic tests for performing memory reads and writes over the remote connection interface.
• Loop Speed - Configures diagnostic tests for performing repeated memory reads and writes over the remote connection interface.
• Memory Tests - Configures the memory tests that you can run on the target.
  Note: The Use Target CPU group appears grayed-out and is not applicable for the HCS08 and RS08 Target Tasks. Refer the CodeWarrior Common Features Guide for detailed documentation of the various options available in the Hardware Diagnostics Action window.
