stack
To dump a stack trace of frames, use the stack command.
stack [-d | -m] [num]
Syntax Description
Defaults The default for num is five frames.
Command Types ROM monitor command.
Command Modes Normal.
Usage Guidelines The frames are dumped from the kernel stack and the process stack (if one is available) of a booted
image. Use the frame command to display an individual stack frame.
The minus sign (-) is required with the -d and -m options.
Examples This example shows how to use the stack command to dump a stack trace of eight frames:
rommon 5 > stack 8
