Firmware Banks
The BLACKBOX Portable implements a comprehensive firmware manage-
ment mechanism designed to insure a failure-free field upgrading functional-
ity. The mechanism insures that at any time there are two firmware images
available, where only one is active, which means running, another is availa-
ble to be upgraded.
The firmware images are stored in a dedicated non-volatile flash memory
block referred to as Bank.
The Bank’s status is displayed on the Banks section on Firmware Upgrade
page.
 Active Bank shows which firmware Bank is actually in use.
 Bank A/B version displays a Bank’s firmware and condition. A numeri-
cal- only firmware name means valid firmware, which is ready to use. In
some situations the firmware could be further marked with a prefix char-
acter to identify a firmware status. The table below describes status pre-
fixes available:
Prefix
Status
“*”
(Asterisk)
The firmware was upgraded and reboot is pending to activate the
image for the first time. The user is free to initiate reboot manually
to complete the upgrading procedure.
“F”
The firmware image failed to complete the initialization process
successfully. The firmware was declared as “Faulty”, another bank
is being used.
“+”
The firmware bank is being upgraded at the moment, wait for a
completion.
“E”
The bank is empty.
For example, if firmware 0.3.52.0 would be found faulty/damaged/corrupted
it will appear as F0.3.52.0 on the Bank A/B version field. In such a case it is
recommended to check if the firmware file is authentic and attempt to up-
grade it again.
