format

Use the format command to format a Flash PC card. A Flash PC card must be formatted before it can be used.

Syntax Description

spare spare_num	(Optional) Number of spare sectors to reserve when other sectors fail.
m/	(Optional) Module number of the supervisor engine containing the Flash device.
device1:	Flash device to be formatted.
device2:	(Optional) Flash device that contains the monlib file to be used to format device1:.
monlib-filename	(Optional) Name of the monlib file.

Defaults

The default number of spare sectors is 0.

Command Types

Switch command.

Command Modes

Privileged.

Usage Guidelines

A colon (:) is required after the specified device.

You can reserve up to 16 spare sectors for use when other sectors fail. If you do not reserve a spare sector and later some sectors fail, you will have to reformat the entire Flash memory, which will erase all existing data.

The monlib file is the ROM monitor library used by the ROM monitor to access files in the Flash file system. It is also compiled into the system image. In the command syntax, device1: is the device to format and device2: contains the monlib file to use.

When you omit the [[device2:][monlib-filename]] argument, the system formats device1: using the monlib that is bundled with the system software.

When you omit device2: from the [[device2:][monlib-filename]] argument, the system formats device1: using the named monlib file from the device specified by the cd command.

When you omit monlib-filename from the [[device2:][monlib-filename]] argument, the system formats device1: using the monlib file from device2:. When you specify the whole [[device2:][monlib-filename]] argument, the system formats device1: using the specified monlib file from the specified device.

You can also specify device1:monlib-filename as the device and filename to be used, as follows:

If monlib-filename is omitted, the system formats device1: using the built-in monlib file on the device.

Note   When the system cannot find a monlib file, the system terminates the formatting process.

Examples

This example shows how to format a Flash PC card:

Console> (enable) format slot0:
All sectors will be erased, proceed (y/n) [n]?y
Enter volume id (up to 31 characters):
Formatting sector 1
Format device slot0 completed.
Console> (enable) 
 

frame

Use the frame command to display an individual stack frame.

Syntax Description

-d	(Optional) Keyword to specify a monitor context.
-p	(Optional) Keyword to specify a booted image process level context.
num	(Optional) Number of the frame to display, where 0 = youngest frame.

Defaults

The default is a booted image kernel context—the youngest frame.

Command Types

ROM monitor command.

Command Types

Normal.

Usage Guidelines

The minus sign (-) is required with the -d and -p options.

Examples

This example shows how to use the frame command to specify a booted image process level context, frame 1:

rommon 6 > frame -p 1
Stack Frame 1, SP = 0x80007ed8, Size = 32 bytes
[0x80007ed8 : sp + 0x000] = 0x6031de50
[0x80007edc : sp + 0x004] = 0x6031c000
[0x80007ee0 : sp + 0x008] = 0x00000000
[0x80007ee4 : sp + 0x00c] = 0x80007ec4
[0x80007ee8 : sp + 0x010] = 0x00000002
[0x80007eec : sp + 0x014] = 0x00000000
[0x80007ef0 : sp + 0x018] = 0x60008770
[0x80007ef4 : sp + 0x01c] = 0x600087f0
 

history—ROM monitor

Use the history command to display the command history (the last 16 commands executed in the ROM monitor environment). This command is aliased to "h" by the ROM monitor for convenience.

Syntax Description

This command has no arguments or keywords.

Defaults

This command has no default setting.

Command Types

ROM monitor command.

Command Modes

Normal.

Examples

This example shows how to use the history command:

rommon 13 > history
 
1   help
2   break -s 0x20090
3   break -s 10090
4   break -s 0xa0001000
5   cont
6   help
7   dev
8   dir 
9   dir bootflash:
10  dis
11  dis 0xa0001000
12  dis 0xbe000000
13  history
=============================================================================

history—switch

Use the history command to show the contents of the command history buffer.

Syntax Description

This command has no arguments or keywords.

Defaults

This command has no default setting.

Command Types

Switch command.

Command Modes

Normal.

Usage Guidelines

The history buffer size is fixed at 20 commands. See the "Command-Line Interfaces" chapter for detailed information about the command history feature.

Examples

In this example, the history command lists the contents of the command history buffer:

Console> history
       1 help
       2 history
Console> !2
history
       1 help
       2 history
       3 history

Syntax Description

-l	(Optional) Keyword to specify long listing—displays DRAM configurations.

Defaults

This command has no default setting.

Command Types

ROM monitor command.

Command Modes

Normal.

Usage Guidelines

The minus sign (-) is required with the -l option.

Examples

This example shows how to use the meminfo command:

rommon 9 > meminfo
 
Main memory size: 16 MB in 32 bit mode.
Available main memory starts at 0xa000e000, size 16328KB
IO (packet) memory size: 25 percent of main memory.
NVRAM size: 32KB
