Model 5152
Video Generator/Audio Embedder Module
pretty much everything but the SDI-related
tasks. 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, process-
es the SDI signals, and handles audio em-
bedding. 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
archive 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 indi-
cate 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 successfully installed.
Note: The firmware update procedure
itself will not erase or overwrite bitmap
image files that are already saved in the
Model 5152. 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 5152 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 (m5152.
s19) and FPGA (m5152.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 5152 module.
4. Insert the prepared USB flash drive into
the module’s USB port.
5. Apply power to the Model 5152 module.
6. The module will run a “boot loader”
program that will immediately load the
new MCU (
m5152.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
operation. It will process video and
audio as well as checking for an FPGA
(m5152.bit) file on the USB flash drive.
If it doesn’t find this file normal opera-
tion will continue. If it locates this file it
will begin to load it from the USB flash
drive. In that case, some Model 5152
