Chapter 7 Command Line Interface (CLI) 83

R2MFC Media Bay Module Installation and Configuration Guide

Table 24 includes the CLI commands for the Software Error (SWerr) utility. The firmware stores 
the Swerr messages into a cyclic buffer. The contents of the buffer are printed upon request.The 
commands are accessed from the SWerr directory. 

Table 24   SWerr directory CLI commands

PS <num>

Prints the Swerr buffer constants. All the accumulated swerr messages are 

printed.

Where:
num is the number of error messages to print (optional).

The buffer stores the 20 most recent messages.

GF

Displays the swerr error levels and control flags.

There are three error levels: inform, serious, and fatal. Each level has two 

flags: Insert_flag, which stores error information in the buffer, and Print_flag, 

which prints to the serial port when an error occurs.

CF <level> <insert_flag> 

<Fast_print_flag> 

<user_func_addr>

Changes swerr control flags.

Where:
level is in the range of 0...2.
insert_flag is true or false
Fast_print_flag is in the range of 0...2 (0 = print, 1 = print, 2 = fast print).
user_func_addr is the user function address (for firmware engineers only).

DEL < number>

Deletes swerr messages from the buffer.

Where:
number is the number of swerr messages to delete (oldest messages are 

deleted). Enter 0 to delete all swerr messages.

DWN

Prints detailed debug information for one swerr message, stepping down 

(back in time).

UP

Prints detailed debug information for one swerr message, stepping up 

(forward in time).

PP

Prints detailed debug information for the current swerr message.

HeLP
