Recovering the Monitor
1 Make sure that a monitor ROM device is installed in the PLCC socket on the KAT4000.
2 Ensure there is a jumper on JP7, across pins 1 and 2.
3 Issue the following command, where serial_number is the board’s serial number, at the
monitor prompt:
KAT4000 (1.0) => moninit serial_number
moninit will also reset environment variables to the default state.
4 To boot from soldered flash, power down the board and remove the jumper from JP7, pins 1
and 2.
The monitor always resides in the top 512 KB block of NOR flash as shown in
Table 14-3.
