Possible Problem

Possible Resolution:

 

 

 

 

 

 

 

IV. Debug prompt

 

2. At the command line prompt, type in:

 

 

PPC6-Bug>

 

env;d <CR>

 

 

appears at

 

(this sets up the default parameters for the debugger

 

 

powerup; the

 

environment).

 

 

board does not

 

3. When prompted to Update Non-Volatile RAM, type in:

 

 

autoboot

 

y <CR>

 

 

(Continued)

 

4. When prompted to Reset Local System, type in:

 

 

 

 

 

 

 

 

y <CR>

 

 

 

 

5. After clock speed is displayed, immediately (within five

 

 

 

 

seconds) press the Return key:

 

 

 

 

<CR>

 

 

 

 

-or-

 

 

 

 

BREAK

 

 

 

 

to exit to the System Menu. Then enter a 3 for “Go to

 

 

 

 

System Debugger” and Return: 3 <CR>

 

 

 

 

Now the prompt should be: PPC6-Diag>

 

 

 

 

6. You may need to use the cnfg command (see your

 

 

 

 

board Debugger Manual) to change clock speed and/or

 

 

 

 

Ethernet Address, and then later return to:

 

 

 

 

env <CR>

 

 

 

 

and step 3.

 

 

 

 

7. Run the selftests by typing in:

 

 

 

 

st <CR>

 

 

 

 

The tests take as much as 10 minutes, depending on

 

 

 

 

RAM size. They are complete when the prompt returns.

 

 

 

 

(The onboard selftest is a valuable tool in isolating

 

 

 

 

defects.)

 

 

 

 

8. The system may indicate that it has passed all the

 

 

 

 

selftests. Or, it may indicate a test that failed. If neither

 

 

 

 

happens, enter: de <CR>

 

 

 

 

Any errors should now be displayed. If there are any

 

 

 

 

errors, go to step VI. If there are no errors, go to step V.
