Restoring the PmPPC7448 Monitor Using the KatanaQP
To restore the PmPPC7448 monitor image from the soldered flash, the monitor image can
be copied to the KatanaQP carrier’s RAM, to the soldered flash, and finally to the socket
flash (EEPROM) via a PCI interface. The KatanaQP’s socket flash can then be removed and
placed on any PmPPC7448’s DMC. Follow the instructions below to copy the monitor
image from the PmPPC7448 to the socket flash on the KatanaQP.

Note:
This example shows how to port linux kernel images in the monitor, however copying a monitor image uses
the same steps.

Note:
This example assumes that the os kernel in the KatanaQP already sits at flash memory starting at
0xe8100000. The size of the data chunk is 1.6MB <2MB.

1
Firmly insert the PmPPC7448 on one of the four PMC slots on the KatanaQP.
2
Setup two console terminals with the first for the KatanaQP console and the second for the
PmPPC7448 console.

3
Boot the KatanaQP and bring it to the monitor prompt.
4
Enter showpci at the command prompt.
