DESCRIPTION: This command is used to verify the integrity of file(s) loaded in the
data buffer (of the currently specified core). It can verify both OS
images as well as the initrd filesystem.
The md5sum file must have the same 128-bit fingerprint as
generated by the GNU utility “md5sum”.
The “-b” option permits selective performance of md5sum checking.
In particular, in a configuration file it can be used in conjunction with
the LOAD command to provide full control over the image loading
and starting process. Refer to the example provided with the LOAD
command.
