7
Cause. The PRV ON command must be executed in order to use a privileged
command.
Effect. The command is not executed.
Recovery. Enter the PRV ON command and try again.
8
Cause. The command attempts to set a breakpoint with a command string, but Debug
requires system buffer space that is not available.
Effect. The command is not executed.
Recovery. There is no corrective action possible for the entered command. If
possible, try to debug your process on a different processor. Otherwise, enter the
break (B) or break memory (BM) command without the command string.
9
Cause. The specified command requested Debug to convert a number that will
overflow 32 bits or to perform an arithmetic operation that will overflow the available
space.
Effect. The command is not executed.
Recovery. Correct the command so that no overflow occurs, and try again.
11
Cause. The trace (T) command encountered an error while attempting to analyze the
stack.
Effect. The command might or might not display some output information.
Recovery. Contact your service provider with all the necessary information to
reproduce the problem.
PRV ON is required to perform command.
Could not get memory to hold break information.
An arithmetic overflow occurred while computing the address.
