Did you check this issue with the default image that comes with the Digi BSP on Digi's development board?
If you test with custom image, what are the modifications have you done in the catalog items?
Can you provide your boot log information here?
Also go through the below description about the registry.
While working with the target, interface settings and OS parameters can be modified, for example, network settings and memory configuration. These changes are saved to the target's Windows Registry, a database that stores settings and options for your target's operating system. Because the target's Registry resides in RAM memory, these settings are lost when the target is powered off.
The regtool application stores the Registry into NVRAM so the settings are not lost.
To see the application’s syntax, execute it with the –h option:
Hive based registry :
\> regtool –h
Application to save or erase the Registry. Revision 1.1
Copyright(c) 2007 by Digi International Inc.
Usage: regtool <options>
Where options are:
-s Save registry to flash
-h Show this helps
--> -s: Saves the Registry to a file in the flash file system.
When the system boots, if it finds a correct Registry in the nand flash, it loads these settings for the running system. Otherwise, the system generates a Registry in RAM with default values.
So once the system booted properly try to use the below command
It may resolve your issue.
