Procedure for upgrading firmware on a WavBox player:

 

 

A command line utility is available to program the firmware to a SPI EEPROM on the 
WavBox.  
 
If you require a copy, please contact us on 01243 837835 or email us on 

info@fearfx.co.uk

.   

 
Just extract the uniprom zip file to a folder such as "c:\uniprom". The firmware image is 

called “eeprom.img" which needs to be in the same folder.  

If you use a COM port other than COM1, edit the "uniprom.bat" file's "-p #" parameter. 

 
The name of the file is always "eeprom.img".  

 
 

 

Connect WavBox player RS232 connection to COM 1 on the computer (see note above on 
how to select a port other than COM 1). 

 

Remove SD Card from the WavBox. 

 

Remove the 4 screws securing the lid. 

 

Move S8 (Run/Prog) switch to the Prog position. 

 

Reset board, by pressing the reset button or removing and restoring power. 

 

Move S8 (Run/Prog) switch to the Run position.

 

 

Double click on the “uniprom.bat" file to launch the programmer. 

 

o

 

You can also open a command 
prompt    and run “uniprom” 
from there, using this method 
means that the command 
window will not close when it 
has completed the procedure. A 
command prompt short cut is 
included in the uniprom folder 
(assumes running from 
“c:uniprom”)

 

 

The programmer will perform various 
checks before opening the 
“eeprom.img” file and programming 
and then verifying the installation. 

 

Once complete reboot the player. 

 

You may notice that the left/right balance is incorrect after firmware update. To correct 
this raise the volume to maximum (when maximum is reached an audible blip will be 
heard). The volume can now be returned to the required setting. 

 

 

Progamming and 

verifying stage.
