Software Upgrade
There are two phases to the COM24 software upgrade sequence. The initial phase is referred to
as the bootloader, and it is at this time that the card evaluates requests for a software upgrade.
The second phase, also known as the updater, is when the new code is downloaded,
authenticated, and installed to the card.
During the initial phase of the software upgrade procedure (the bootloader), a COM24 first
evaluates requests for software updates and then verifies that the code to be installed is indeed a
valid COM24 software release. During the bootloader phase, the status can be determined by
evaluating the LED states according to
