To redirect a file from the SRAM of the target group to the flash ROM memory of
the same file group, insert the zero-length SETDRIVE.F file into the batch of
application files to download. All files that follow the SETDRIVE.F file in the
download list automatically load into the flash ROM memory (F:) of the target
group.
If you do not insert a SETDRIVE.F special file in the download list, all files
download by default into the SRAM (Drive I:) of the target file group. You can also
insert a zero-length file with the name SETDRIVE.I into the download list at any
point to indicate that all following files will download into SRAM.
For example, the following batch download list loads the executable code file
FOO.OUT into the SRAM of the selected file group (default Group 1). Because
the signature file, FOO.P7S is included, FOO.OUT is also authenticated when the
device restarts after the download.
The *GO variable in this example indicates that the FOO.OUT application
executes on restart, after successful authentication. The two data files that follow
the zero-length SETDRIVE.F file, FOO.DAT and FOO.VFT, are redirected into
GID1 flash ROM. Because it follows the inserted zero-length SETDRIVE.I file,
GOO.DAT downloads into Group 1 SRAM.

You can also insert zero-length SETGROUP.n files into a batch download list to
redirect files from the target file group to other file groups (see
Other File Groups). Together, the zero-length SETDRIVE.x and SETGROUP.n
files allow you flexibility to store files as required in the SRAM or flash ROM file
systems, and in specific file groups in a single batch download operation.
You can only use zero-length SETDRIVE.x files for batch application direct
NOTE
downloads, and only using the DMM download tool (and not DDL.EXE).
You cannot use this special file convention for operating system downloads or for
back-to-back application downloads.
