Upgrade Procedure from Version 1.0.0.25
All software released after version 1.0.0.25 requires additional FLASH sectors beyond the current amount of FLASH sectors currently allocated for the image. Therefore the FLASH sectors must be reordered before downloading the new software. This will be accomplished by first downloading an interim version, and only after that loading the actual released version.
Note
Due to new Board Support Package (BSP) there is also an updated Boot code: version
1.0.0.7.This can be uploaded regardless of the SW image (ROS version) running on the device. Therefore, boot upgrade can be performed before or after the upgrade procedure described below
The interim version provided reorders the FLASH allocation without the need to erase the FLASH and downloading the new software via the serial cable using XMODEM. Hence, the

Note
During the software upgrade ensure the following:
—Ensure that the device is not powered down or that a power cable is not disconnected during the software upgrade. If the device is powered down or if a cable is disconnected, once device is reconnected the software upgrade must be downloaded via XMODEM
—Ensure that the device configuration is backed up to an external server/station.
—Do not use the interim code drop for Quality Assurance testing, field upgrades etc; use only the final code drop
—When running the interim version, the initialization stage takes a relatively long time
The user will have to run the following steps in order to successfully completing the upgrade procedure:
1. Back up configuration files to an external device.
