7.3.11.2 Code Loading
The Code Load option of the CLCP utility is invoked from an external processor
(typically a personal computer) connected to the maintenance terminal port on
the front bezel of the controller. The processor must be configured to run the
KERMIT terminal protocol at 19,200 baud, with 8 data bits, no parity, and one
stop bit. When running the Code Load option of the CLCP utility from a personal
computer, all screen savers should be disabled. Screen savers are terminate-and-
stay-ready (TSR) programs that can interfere with the code loading process.
To perform a code load operation, a file containing the new firmware image must
be stored in the external processor. The file must be in binary image format. The
binary firmware image file can be obtained from your Digital representative.
Contact your Digital representative for more details on the distribution of
firmware updates.
The user invokes the CLCP utility from the CLI via the external processor. The
CLCP program then waits to be downloaded from the external processor via the
serial interface and the KERMIT file transfer protocol.
Once loaded into the HSZ40–Bx controller’s memory, the new image is written
into the controller’s PCMCIA program card. The Code Load program then
automatically initializes the controller to place the new controller firmware
into effect.
7.3.11.3 Using Code Load
Note
If you run the Code Load option of the CLCP utility from a personal
computer, disable all screen savers while the code load program is in
process.
Operate the Code Load utility as follows:
1. Load the binary firmware image file into the external processor using file or
network transfer utilities appropriate to the operating environment of the
external processor.
2. Invoke the CLCP utility and select the Code Load option as follows:
CLI> RUN CLCP
Select an option from the following list:
Code Load & Code Patch local program Main Menu:
0: Exit
1: Enter Code LOAD local program
2: Enter Code PATCH local program
Enter option number (0..2) [0] ? 1
---------------------------------------------------------------
You have selected the Code Load local program. This program is
used to load a new firmware image on the program card currently
inserted in the controller. The file transfer is performed using
a computer running the KERMIT file transfer protocol. This computer
is connected via a serial communication line to the service port on
the controller board.
Type ^Y or ^C (then RETURN) at any time to abort Code Load.
