Model 5150
Video Generator Module
copied to the USB flash drive should be
noted for later reference. Once the new
files are loaded into a Model 5150 the
module’s front-panel LEDs should be used
to confirm that the correct firmware ver-
sions have been successfully installed.
Note: The firmware update procedure
itself will not erase or overwrite bitmap
image files that are already saved in the
Model 5150. However, this requires that
the custom image files (img720.bmp and
img1080.bmp) are not present on the
USB flash drive.
To install the firmware files:
1. Power down the Model 5150 module
you intend to upgrade.
2. Ensure nothing is inserted into the
USB port on the module. Power up
the module and “read” the version
numbers of the currently-installed
MCU (m5150.s19) and FPGA
(m5150.bit) files. Write these numbers
down for reference. The next section
of this guide details how to “read” the
installed firmware version levels.
3. Power down the Model 5150 module.
4. Insert the prepared USB flash drive into
the module’s USB port.
5. Apply power to the Model 5150 module.
6. The module will run a “boot loader”
program that will immediately load the
new MCU (
m5150.s19) file. This takes
approximately eight seconds. Once the
file is loaded the module will perform
a normal power-up sequence with the
microcontroller using its newly-loaded
MCU firmware.
7. After the power-up sequence has been
completed the module will begin op-
eration. It will process video as well
as checking for an FPGA ( m5150.bit)
file on the USB flash drive. If it doesn’t
find this file normal operation will con-
tinue. If it locates this file it will begin to
load it from the USB flash drive. In that
case, some Model 5150 functions will
halt, including reading changes to the
configuration switches. As an indication
that the file transfer is under way, the
USB Activity LED will flash on and off.
8. The process of loading the FPGA
(m5150.bit) file will take approximately
90 seconds to complete. When the
file loading process is complete you
will see the module’s front-panel USB
Activity LED change from flashing to
being continuously lit. At that time the
Model 5150’s logic chip (FPGA) will
reboot and run under the newly-loaded
firmware.
9. Power down the module.
10. Remove the USB flash drive from the
module’s USB port.
11. Power up the Model 5150 module and
it will begin operation using the updated
MCU and FPGA firmware. The ver-
sion numbers of the installed MCU and
FPGA firmware should be “read” by
way of the front-panel LEDs. Compare
and confirm that these numbers match
those from the zip file names that were
provided by the factory.
Note: It’s possible that during the update
process any LEDs located on the USB
flash drive may light steadily or flash with
varying patterns. These actions are not
significant to the Model 5150’s firmware
update process. (The status LEDs on vari-
ous USB flash drives seem to behave in
different ways so there are no universal
patterns that can be identified.)
