Acquisition Modules and Platinum Firmware
Platinum Firmware Upgrades
3.
Wait for the device to be scanned and registered by the operating system. You
can confirm this by looking for USB mass storage registration entries in the system
log file, /var/log/messages.
4.
Mount the file system by entering the following command:
mount -t ext2 -o ro /dev/disk/by-label/Pt-firmware /mnt
Note: Some early Platinum releases only had ext3 file-system
support. If this is the case, the above command will result in
an "Invalid argument" error message. If this occurs, simply
change ext2 in the above command to ext3.
5.
Run the upgrade script.
This is not the same script that is used for network upgrades but it takes the same
optional arguments. These arguments are documented in section 5.4 on page 61,
which should be read before proceeding.
Once you have decided which argument, if any, you wish to use, run the script
with the command:
/mnt/upgrade optional_argument
6.
Ensure there are no error messages and then reboot the device. Once the unit
has rebooted, the upgrade process is complete.
Note: Certain upgrades (depending on the initial version number)
make it difficult or impossible to reboot the system via the web
interface. In these cases, the system can be rebooted from the
command line (with the reboot command) or by power-cycling.
5.3.4 U3 USB mounting problems
U3 was a method of launching Windows applications from special USB flash
drives. A U3 flash drive presents itself to the host system as a USB hub with a
CD drive and standard USB mass storage device attached.
Reformatting the drive will remove some of the software (the hidden
"SYSTEM" folder), but not all of it. The virtual CD-ROM drive cannot be
removed by reformatting because it is presented to the host system as a
physical device attached to a USB hub.
U3 Tool is an open-source management tool (for Windows and Linux) that
allows the locked U3 partition to be removed.
