Appendix C. Recovery from Upgrade
The DWC-1000 has a feature to allow for recovering from a corrupted firmware upgrade event.
In rare occurrences the firmware upgrade operation can fail and render the web UI inaccessible.
To recover, follow the following instructions.
1. Connect your LAN host that has a verified firmware image located on it to the LAN of
the DWC-1000. The host's IP address should be in the 192.168.1.x subnet.
2. You can force the controller into "Recovery Mode"by:
a. Turn on "Power" and push "Reset" button. The system LED will flash 5 times
and the system will be in recovery mode.
b. If during upgrade the firmware checksum integrity check fails, the system will
reboot and the system LED will flash 5 times. This indicates that recovery mode
has been entered.
3. The DWC-1000 LAN IP address is 192.168.1.1 and open this site with any browser .
4. Select the firmware image on your host – these screens will allow you to upload the full
DWC-1000 firmware image to restore full system functionality prior to the upgrade issue.
The following screenshots demonstrate the expected display when the system is in recovery
mode.
