HP LCS60 manual Memory Dump

Memory Dump

If the LCS60 hangs and a memory dump is required, do the following:

1. Log the console session on a PC, if possible. Information must be recorded to evaluate the dump, and logging the session is, therefore, required.

2. Display the debugger prompt by pressing the 197 board Abort button. (Refer to Figure 9-1).

Caution: Do not use the memory status (

Reset button, this will clear the current Abort leaves the current status intact).

Pressing the Abort button will dump all of the current program regis- ters to the screen. This information is vital.

3. A typical register dump is shown in the screen below:
