presented in these configuration files. If this is the case, you are asked to note any
changes to settings you have made to these files, and to perform the upgrade in a
way that overwrites these configuration files. You then need to edit these text files,
reapplying your changes.
If you are starting from an earlier version of shelfman (prior to PPS 2.5.2), your
configuration files will not be preserved across an upgrade, and you will need to
restore any special configuration settings by editing the .conf files after the upgrade
2. Upgrading the U-boot, kernel, and root file system images
This is the normal upgrade sequence.
3. Upgrading the FPGA firmware on the SAM
The startup logic (following the root file system upgrade) automatically detects the
need to upgrade the FPGA. If an upgrade is necessary, the startup logic loads the
FPGA and automatically reboots the ShM again. If this occurs, you should note a
delay of approximately 5-8 minutes while this download occurs.
4. Updating the default U-boot environment variable configuration
The upgrade procedure preserves all U-boot environment variables. No special
procedures are necessary.
Start the following sequence of operations with the backup Shelf Manager.
The list below outlines the different actions required to enable and use the front panel Ethernet
interface on a SAM. If the upgrade is being performed over the backplane Ethernet interfaces
from one of the hub boards, skip these steps.
1. Login to the SAM front panel serial console using the id root and password root. Earlier
firmware versions use the password motorola.
2. Set the environment variable that defines the IP address allocated for the SAM's front panel
Ethernet interface.
# setenv ip1addr W.X.Y.Z (substituting your address)
# ifconfig eth1 W.X.Y.Z
3. If your file server (for Emerson files) is on a different subnet, :
# route add default gw W.X.Y.Z (you will need to do this each time you reboot)
If you use the Uboot environment variable gatewayip, the route is set automatically at reboot
(setenv gatewayip W.X.Y.X)
4. If the local subnet is not a class 'C' subnet, you may need to also execute the command:
# ifconfig eth1 netmask ... to alter the netmask used by the ethernet interface
If you use the Uboot environment variable netmask1, this subnet mask is set automatically
at bootup (setenv netmask1 netmask)
