that are already saved in the Model 5152.
However, this requires that the custom im-
age 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 mod-
ule and “read” the version numbers of
the currently-installed MCU (m5152.s19)
and FPGA (m5152.bit) files. Write these
numbers down for possible future use.
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 module.
6. The module will run a “boot loader”
program that will immediately load the
new MCU (
m5152.s19) file. This takes
approximately six 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 opera-
tion. 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 operation
will continue. If it locates this file it will
begin to load it from the USB flash drive.
In that case, some Model 5152 func-
tions will halt, including reading changes
to the configuration switches. The eight
signal present LEDs will also not light
even though embedding might be tak-
ing place. 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 lit solid. 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 module and it will begin
operation using the updated MCU and
FPGA firmware. The version numbers
of the installed MCU and FPGA firm-
ware should be “read” by way of the
front-panel LEDs. Compare these num-
bers to the names of the zip files 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 firmware update process.
(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
Some of the status LEDs on the front pan-
el of the Model 5152 are used during the
power-up sequence to identify the version
