The device fails to load software images.
Common causes
The common cause of this type of issue is that the software image file is corrupted.
Solution
1. Execute the md5sum command in user view to use the MD5 algorithm to calculate the MD5 digest of the software image file. In this example, the flash memory is used as the storage medium.
<Sysname> md5sum flash:/Comware.ipe
MD5 digest:
