Firmware Update - Lectrosonics DCR822 Instruction Manual

Firmware Update

Firmware updates are made using a microSDHC
memory card. Download and copy the following firm-
ware update files to a drive on your computer.
• DCR822 vX_xx.hex is the firmware update file,
where "X_xx" is the revision number.
In the computer:
1) Perform a Quick Format of the card. On a Win-
dows-based system, this will automatically format
the card to the FAT32 format, which is the Windows
standard. On a Mac, you may be given several
options. If the card is already formatted in Win-
dows (FAT32) - it will be greyed out - then you do
not need to do anything. If the card is in another
format, choose Windows (FAT32) and then click
"Erase". When the quick format on the computer is
complete, close the dialogue box and open the file
browser.
2) Copy the DCR822 vX_xx.hex and DCR822_fpga_
vx_xx.mcs files to the memory card, then safely
eject the card from the computer.
In the DCR822:
1) Leave the DCR822 turned off and insert the mi-
croSDHC memory card into the slot.
2) Hold down both the UP and DOWN arrow buttons
on the receiver and turn the power on.
3) The device will boot up into the firmware update
mode with the following options on the LCD:
• Update - Displays a scrollable list of the program
files on the card.
• Power Off - Exits the update mode and turns the
power off without updating.
NOTE: If the unit screen shows FORMAT CARD?,
power the unit off and repeat step 2. You were not
properly pressing UP, DOWN and Power at the
same time.
4) Use the arrow buttons to select Update, then press
the MENU/SEL button. Use the UP and DOWN
arrow buttons to select the desired file and press
MENU/SEL to install the firmware. The LCD will
display status messages while the firmware is being
updated.
5) When the update is complete, the LCD will display
this message: UPDATE SUCCESSFUL REMOVE
CARD. Remove the memory card or use the back
button to return to the update page.
6) Once finished with updates, power the unit back
on. Verify that the firmware version was updated by
opening the Power Button Menu and navigating to
the About item.
7) If you re-insert the update card and turn the power
back on for normal use, the LCD will display a mes-
sage prompting you to format the card:
Rio Rancho, NM
Dual Channel Digital Receiver
Format Card?
If you wish to record audio on the card, you must
re-format it. Select Yes and press MENU/SEL to
format the card. When the process is complete, the
LCD will return to the Main Window and be ready
for normal operation.
If you choose to keep the card as is, you may re-
move the card at this time.
The firmware update process is managed by a boot-
loader program - on very rare occasions, you might
need to update the bootloader.
WARNING: Updating the bootloader can
corrupt your unit if interrupted. Don't update
the bootloader unless advised to do so by the
factory.
• DCR822_boot vX_xx.hex is the bootloader file
Follow the same process as with a firmware update and
select the DCR822boot file.
NOTE: The ability to perform firmware updates
via the USB port will be built into a future update.
Check the Firmware Release Notes as updates
are announced.
