Speedway Reader IPJ-R1000 for Gen 2 UHF RFID

section 7.5.2.1.

6.9.2. Upgrade decision

Not all upgrade attempts will result in an actual upgrade, even if the upgrade file is valid. The reader’s upgrade decision is

based on the following factors:

• The image versions of the SOP and CAP partition of the primary image.

• The image version(s) of the partition(s) in the upgrade metafile and the upgrade image files downloaded, as well as

the number of partitions present.

• The image type of the primary image, as well as the type indicated by the image metafile and upgrade file.

• The upgrade mode, forced or auto, as indicated in the upgrade metafile.

In auto upgrade mode, the upgrade will happen only when either one of the following is true:

• The upgrade image has the same type as the primary image and at least one partition in the upgrade image has a

version higher than the corresponding version in primary image. In this case the partition in the upgrade file that has

lower version number than the one in primary image will not be used, instead the current primary partition will be

kept.

• The upgrade image has different image type from the primary and SOP is present in the upgrade file.

In forced upgrade mode, an upgrade will happen as long as at least one partition in upgrade file has a different version from the

primary image. If the upgrade is started with config image upgrade command, the upgrade is always performed regardless of

version numbers.

6.9.3. Partition copy-over

The upgrade image file does not necessarily contain all the partitions. The missing partition(s) will be copied over to the

secondary image from the primary image upon reboot after upgrade whenever applicable. The behavior is as follows:

• If the upgrade file has image type same as the primary image, then

• If the upgrade file contains SOP only, primary SCP and CAP (if present) are copied over.

• If the upgrade file contains SOP and CAP, primary SCP is copied over.

• If the upgrade file contains CAP, the primary SOP and SCP are copied over.

• If the upgrade file contains SOP and SCP, primary CAP, if present, is copied over.

• Else if the upgrade file has a different image type from the primary image, no partition is copied over. The new

image will use the factory default configuration if there is no SCP in the upgrade file.

Such copy-over behavior allows the current configuration and custom application to be carried over to the new image after an

upgrade.

6.9.4. Image partitions already programmed

There are cases when the partitions in the upgrade file are already on the secondary image. For example, when a reboot is

scheduled in 10 hours following a successful upgrade and the reader is pulling the metafile every 10 minutes, it will find that

the same partitions in the metafile already programmed on the secondary image. To avoid unnecessary programming of flash,

the reader checks if any or all of the intended partitions are already programmed and the behavior in these cases is as follows:

• If the upgrade file contains SOP only and it is already on the secondary image, there is no reprogramming of flash

except for marking the primary SCP, and CAP if present, to be copied over upon reboot after upgrade. (See section

6.9.3)

• If the upgrade file contains SOP and CAP and both are already on the secondary image, there is no reprogramming of

flash except for marking the primary SCP to be copied over upon reboot after upgrade.

• If the upgrade file contains CAP only and it is already on the secondary image, the primary SOP is copied to

secondary image and the primary SCP is marked as to be copied over upon reboot after upgrade.

Note that these behaviors only apply to automatic upgrades performed via the periodic pull method with auto or forced upgrade

mode. When the upgrade is manually pushed with the config image upgrade command, the flash is always programmed with

the upgrade image regardless of the versions on the primary and secondary images.
