LOAD (NAND Flash)

FUNCTION: Load an operating system image and optionally a RAMdisk

filesystem from the NAND Flash to the data buffer

SYNTAX:

load [-b] [-r <filenameRD>] <filenameOS>

where:

load command

-b option: backup

only load file(s) if image(s) in data buffer invalid, or

the md5sum check(s) failed

-r option: ramdisk

load initrd specified by <filenameRD>

<filenameRD> parameter: string

<[x … ]x>

filename of initrd

<filenameOS> parameter: string

<[x … ]x>

filename of operating system image

DESCRIPTION: The LOAD command is basically designed to transfer an OS image

from the NAND Flash to the data buffer (of the currently specified

core) for system booting. For OSs requiring a RAMdisk filesystem,

the option “-r <filenameRD>” is available.

The “-b” option (backup) permits selective file loading. When used in

a configuration file, a series of LOAD commands may be included to

ensure that if the first LOAD command fails (data buffer image invalid

or md5sum check failed), the loading of a second (or third, etc.) file

can be defined.

In conjunction with the MD5 and RUN commands using the “-b” and

“-c” options respectively, a very high degree of system integrity can

be achieved.
