CCG3’s internal device flash contains two copies of firmware that can mutually update each other. These copies
are called FW1 and FW2, and are designed to be placed at different flash locations.
If the CCG3 device is currently running FW1, only FW2 can be updated and vice-versa. The user can specify one
or both firmware binaries in the
Firmware Update
binary will be used for the update operation. If the device is currently running FW1, the utility will select the FW2
binary file from the two file locations provided and update FW2 during the process. If no FW2 path is provided by
the user, then an error will be reported.
It is possible to updat
e both FW1 and FW2 binaries simultaneously by using the “
Bootloader Flashing
” option
. In this case, the CCG device enters bootloader mode and updates both firmware banks.
Depending on the status of the CCG3 device and the chosen selections, the ways the firmware update operation
can be run can vary.
hows the possible firmware update options based on the CCG3 device status and
user selection.
After a firmware update process is complete and the CCG3 device is reset, the running firmware automatically
switches to the most recently updated firmware.
