The original file extension does not have to be retained. To make sure the file is clearly
identified, we recommend a name such as the following:
PPP = controller type (R1, R2)
T = R for release (or B for beta)
MM = major revision number
mm = minor revision number
b = build letter
Example of an original firmware filename:
Example of the same firmware file, renamed:
the following directories and their contents if they appear on the card:
/sdcard0/strategy
/sdcard0/boot
/sdcard0/opto22/config
You can write to the card in one of two ways: either use your PC to FTP files to the card in the
controller, or use a card reader with your PC and simply copy files with Windows Explorer.

sdcard0
<file> is the firmware path and file as the microSD card
sees it, so do not include sdcard0 directory in the path.
The firmware file can be compressed in gzip format or
uncompressed. *
<modpos> is the position of the module on the rack.
NOTE: If this file exists, it will be installed. Firmware check-
ing is impossible on serial modules.
CAUTION: Installing the wrong firmware on a serial mod-
ule will make the module unusable. Make sure you have
the correct firmware!
<file> is the firmware path and filename as the microSD
card sees it, so do not include sdcard0 directory in the
path. The firmware file can be compressed in gzip format
or uncompressed.* If you're using Secure Strategy Distri-
bution, <file> must include a valid signature.
NOTE: If installing both module and controller firmware,
make sure the ModKrn command comes before the Krn
command, as Krn resets the controller.
NOTE: Controller firmware will be installed only if it differs
from the current firmware.
