AXP1440 Shelf Installation
AXP1440 Installation and Use (6806800H23U) 103
Procedure - Upgrade the Shelf Manager
NOTE: 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.
The upgrade process involves the following steps.
1. Preserving and restoring configuration settings.
Normally, any configuration settings saved in
/etc/shelfman.conf
and
/etc/shelfman.conf.sam1500
are preserved during the upgrade
procedure (if starting with a version of shelfman that is at revision PPS 2.5.2
or higher), so you do not need to save and restore unique settings saved in
these files. Occasionally, a firmware upgrade presents a change in the
options presented in these configuration files. If this is the case, you can note
any changes to settings you have made to these files and perform the
upgrade so it overwrites these configuration files. You then must edit these
text files to reapply your changes.
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.
5.12.3.1 Establishing Network Connectivity to the SAM
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.
