How do I transfer specific files during a WB45NBT firmware update?

Answer

In the firmware upgrade package, there is a file called "fw.txt". You can add the following lines to transfer the files from the old image to the new upgraded image. For example, to keep the profiles and network setting during the firmware update process, add these three lines in the "fw.txt" file. #transfer-list: /etc/summit/profiles.conf /etc/network/interfaces
