Video Generator/Audio Embedder Module
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 version
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 pro-
cess. (The status LEDs on various 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 soft-
ware), hardware, and configuration param-
eters. These parameters include the version
numbers of the MCU and FPGA firmware
that are stored in the module. This informa-
tion is also available when using a Model
5190 Remote Access Module with the
Model 5152. A third method is also avail-
able to determine the two firmware version
numbers. The Model 5152’s status LEDs
are used during the power-up sequence to
display the numbers in a cryptic but effec-
tive 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 straightforward 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.
4. After a few seconds the USB Activity
LED will go out and the FPGA firmware
version will be 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.
