5.12.3 Shelf Manager Firmware Upgrade
All files should be loaded onto both ShMs using the procedures described here. These files
also contain firmware that is loaded into the SAM1620-D FPGA. The SAM1620-D FPGA is
programmed automatically (if necessary) by the process. As upgrades are released,
SMART EC supplies the current version of these files.
5.12.3.1 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 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 SAM1620-D.
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 SAM1620-D 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.
