MAXnEupg command line parameters:
/i=n.n.n.n n.n.n.n
specifies
the controller's IP address.
(default is 10.40.30.61)
/p=n
n specifies the controller's TCP/IP port number.
(default is 23) (valid is 1-65535)
/f=n
n specifies controller firmware filename
(default is maxn.bin)
/h
for help - display an usage line (no default)
Description of operation:
-
MAXnEupg will verify the existence and the validity of the firmware upgrade file prior to
sending any commands to the controller to erase or program flash.
-
MAXnEupg determines whether there is firmware currently executing on the MAXnet
controller.
If firmware is currently executing then MAXnEupg proceeds to the next step of the upgrade
process. Otherwise, MAXnEupg will report the error and exit.
-
The flash code blocks are erased. If a failure occurs erasing flash, the program is aborted.
-
The firmware file is sent to the controller and the controller programs the flash to the flash
code blocks. Firmware is sent in packets. If any single packet has a transmission error, it
will be resent until the transmission is successful or the user aborts the upgrade program.
The firmware upgrade utility erases the flash memory of the controller during the
upgrade process. While every precaution has been taken to recover from any failures,
the customer should also take every precaution to provide a stable environment for the
upgrade process in order to minimize the chance of an irrecoverable error that would
require the board to be sent back to the factory.
