2.4 NAND Flash Operation
The NetBootLoader provides various functions for performing operations with the NAND Flash
memory. The following table provides an overview of the available NAND Flash memory oper-
ation functions.
SF Store Flash Reads NBL Flash memory to data
buffer
Uses data buffer as target
SL SLoad Download Motorola S-Records Uses data buffer as target

CMD TITLE ALIAS FUNCTION REMARKS
CD, CDCF Change
Directory
Change NAND Flash directory Use CDCF when logged into FTP server
ECAT - Create or view boot script config
files on the NAND Flash
Single line files only
FDISK - Create or remove primary partitions
on the NAND Flash
JUMP - Jump to the specified script in the
NAND Flash (when the current
script has been executed)
Standard boot process only; if encountered
during the alternate boot process (netboot) is
ignored
LOAD - Load an operating system image
and optionally a RAMdisk from
NAND Flash
Uses data buffer as target
LS, LSCF List Directory List NAND Flash directory Lists contents of directory.
MD5 - Perform md5 checksum verification Verifies data buffer contents
MKDIR,
MKDIRCF
Make Directory Create a directory on the NAND
Flash
Use MKDIRCF when logged into FTP
server

specified on the NAND Flash
MV, MVCF - Rename a file on the NAND Flash Use MVCF when logged into FTP server
PWD,
PWDCF
- Display the current NAND Flash
directory path

RM, RMCF - Remove a file on the NAND Flash Use RMCF when logged into FTP server
RMDIR,
RMDIRCF
- Remove a directory on the NAND
Flash
Use RMDIRCF when logged into FTP
server
SAVE - Store contents of the data buffer to
a file in the NAND Flash
