In a typical download procedure, all files are loaded onto the SRAM file system of
the target group selected in system mode. Specific files included in the download
package must be redirected, as necessary, to the flash ROM file system of the
target group or to the SRAM or flash ROM file system of another file group.
To redirect files during a download procedure, see the following sections.
Defragment Flash
ROM for Application
Downloads
Before performing an application download, defragment the device’s flash ROM
memory. To ensure the best results when performing back-to-back downloads,
defragment the flash ROM memory of both the sending and receiving devices. A
system mode procedure is also available for clearing the SRAM or flash ROM
memory, either entirely or for a specific file group, to prepare a V
x
810 for a clean
download.
Redirection of Files
During Application
Downloads
You can download application files into SRAM or flash ROM memory. By default,
files downloaded onto a specific file group are stored in the SRAM of that group.
To store a file in the flash ROM memory of that file group, provide instructions to
redirect the file to flash ROM as part of the procedure (see
Manually Redirecting
Files
).
There are two methods used to redirect files during an application download,
depending on the download tool:
•
If you are using DMM, you must manually create and include special zero-
length files called SETDRIVE.x and SETGROUP.n on the download computer,
and add these files to the batch download list to direct files to a specific file
system (drive) or file group.
•
If you are using DDL.EXE to perform direct downloads, you can use a special
command-line option that automatically redirects files to the drive and file
group you specify.
Both of these methods are described in the following sections.
Manually
Redirecting Files
To manually redirect files for DMM application downloads, create one or more files
on the download computer with the special filename, SETDRIVE.x, where, x is the
name of the partition (memory area) to download files to.
•
Partition designator I: is SRAM: This is the system mode default for
downloads.
•
Partition designator F: is flash ROM.
To create a zero-length SETDRIVE file on the download computer, use the DOS
command, REM, as in the following example:
REM >SETDRIVE.F
NOTE
The flash ROM defragment operation is not necessary for a V
x
810 in a just-out-
of-the-box condition. In this case, the device’s flash ROM file system is still in
factory-new condition.
