Model 5152
Video Generator/Audio Embedder Module
loading process has been completed
the USB Activity LED will change from
flashing to being continuously lit.
Note: If the module is currently output-
ting one of the stored images and a new
image of the same type (“720” or “1080”)
has just completed loading, the output
will automatically change to the new im-
age. (It’s possible that a few seconds of
a solid color could be output during the
transition from the old image to the new
image.)
5. Power down the module.
6. Remove the USB flash drive from the
module’s USB port.
7. Power up the module. It will go through
its normal power-up LED sequence
and begin operation, using the updated
images as appropriate.
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 our update procedure. (The status LEDs
on various USB flash drives seem to
behave in different ways so there are no
universal patterns that can be identified.)
Firmware Update Procedure
It’s possible that updated versions of the
firmware (embedded software) that runs the
Model 5152 will be released to add features
or correct issues. The module has the ability
to automatically load revised files by way of
its USB interface. The Model 5152 imple-
ments a USB host function that directly
supports connection of a USB flash drive.
The Model 5152 uses two firmware files to
perform its functions. One file is used by
the microcontroller integrated circuit (MCU)
and has a file name of m5152.s19. The
microcontroller is the overall “boss” of the
Model 5152. The other firmware file is used
by the logic chip (FPGA) and has a name
of m5152.bit. This firmware, running in the
FPGA, creates the video images, processes
the SDI signals, and handles audio embed-
ding. The factory will provide updates of
these firmware files if it’s warranted for your
specific Model 5152 module.
To update the Model 5152’s firmware is
quite simple but requires careful execution.
The process begins by preparing a USB
flash drive. The flash drive doesn’t have
to be empty (blank) but must be in the
personal-computer-standard FAT32 format.
Save the new firmware files in the root
directory. Their names must be m5152.s19
and m5152.bit. Be certain that any custom
image files (img720.bmp and img1080.
bmp) are not present on the USB flash
drive during this process.
Studio Technologies will supply the MCU
and FPGA files inside individual .zip ar-
chive files. While the firmware file inside
of each zip file will adhere to the naming
convention required by the Model 5152, the
name of the zip file itself will include the
version number. For example, a file named
m5152v1r2MCU.zip would indicate that
version 1.2 of the MCU firmware (
m5152.
s19) is contained within this zip file; a file
named m5152v1r1FPGA.zip would indicate
that version 1.1 of the FPGA (
m5152.bit)
is contained within this zip file. The version
numbers of the files that are copied to the
USB flash drive should be noted for later
reference. Once the new files are loaded
into a Model 5152 the module’s front-panel
LEDs should be used to confirm that the
correct firmware versions have been suc-
cessfully installed.
Note: The firmware update procedure itself
will not erase or overwrite bitmap image files
