+1. Connect the target
+2. Flash old image
+3. Perform the upgrade using the delta file
+4. Wait for the upgrade to complete
+2. Run ./fvt.sh <delta_file>
+
+The fvt.sh script will copy checker.sh and update.cfg from the delta file by sdb and run checker.sh.
+checker.sh will verify that the partitions checksum match.
