MONITOR RECOVERY AND UPDATES

Note:

The monitor provides VxWorks 6.0 support for Error Data and Reporting (EDNR). This feature allocates a per-
sistent area of memory that retains its contents after a systerm soft reset. Any information stored in the 32-
megabyte window starting at 0x1E000000 should stil be available after a soft resset.

This section describes how to recover and/or update the monitor, given one or more of the
following conditions:

• If there is no console output, the monitor may be corrupted and need recovering.

• If the monitor still functions, but is not operating properly, then you may need to reset

the environment variables.

Recovering the Monitor

First, make sure that a monitor ROM device is installed in the PLCC socket. Then, place a
jumper on JP2, across pins 1 and 2 (see

Fig. 2-4

Issue the following command, where serial# is the four digit serial number, 683-xxxx:
[Katana 752i (1.0)] => moninit serial#

Reset the monitor:
[Katana 752i (1.0)] => reset

Reset the environment parameters:
[Katana 752i (1.0)] => envinit serial#

Power down the board and remove the jumper from JP2, pins 1 and 2.
