Model 5152
Video Generator/Audio Embedder Module
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
(m5152.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 5152’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 5152 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 5152’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.)
Identifying the Installed
Firmware Versions
As previously discussed in the Configura-
tion section of this guide, a file is automati-
cally written to a USB flash drive whenever
it is plugged into the Model 5152. This file,
named STATUS.TXT, provides details of
the Model 5152’s firmware (embedded
software), hardware, and configuration
parameters. These parameters include the
version numbers of the MCU and FPGA
firmware that are stored in the module.
This information is also available when
using a Model 5190 Remote Access Mod-
ule with the Model 5152. A third method is
also available to determine the two firm-
ware version numbers. The Model 5152’s
status LEDs are used during the power-up
sequence to display the numbers in a cryp-
tic but effective manner. While the display
method is a bit unique, once a user gets
accustomed to what’s actually happening
during power up it should be fairly straight-
forward to “read” the version numbers.
To identify the installed firmware versions:
1. Power up the Model 5152. The LEDs
will perform a “walk-through” test, with
each LED briefly lighting in a sequence.
2. Next the Power LED will light and
remain lit.
3. Very shortly after the Power LED lights
the USB Activity LED will light to in-
dicate that the MCU firmware version
is being displayed by the eight Digital
Audio Inputs Signal Present LEDs. The
top row of four LEDs will display the
major version number with a range of
1-4. The bottom row of four LEDs will
display the minor version number with
a range of 0 (no LED lit) to 4. Refer to
Figure 10 for details.
