5.12.3 Shelf Manager Firmware Upgrade
There are three files which contain the ShM firmware:
sentry.shmm1500.kernel
,
sentry.shmm1500.rfs
, and
sentry.shmm1500.u-boot.bin
. All files should be
loaded onto both ShMs using the procedures described here.
As upgrades are released, Emerson will supply the current version of these files.
Shelf Manager Upgrade Steps
The upgrade process involves the following steps.
1. Preserving and restoring configuration settings
Normally, any configuration settings you have saved in
/etc/shelfman.conf
and
/etc/shelfman.conf.sam1500
are preserved during the upgrade
procedure (if you are 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, however, a firmware upgrade presents a change in the options
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.
2. Upgrading the U-boot, kernel, and root file system images
This is the normal upgrade sequence.
3. 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.
If you are starting from an earlier version of shelf man (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
