  Is there a size limit, i.e. 32K only?

  Yes, by necessity, since the objective in this case is to produce an .eeprom file that can be accepted by the IDE and handled by the bootloader. That's not to say, though, that a similar program couldn't be written to download more than just 32K.

  In the hopes that this program was written in C is there any chance of getting the source code to it?

  Just a note about unload_prop_source.zip... It requires Win32::SerialPort lib on windows based systems, other systems will need Device::SerialPort, including cygwin, so you will need to edit the file to get it to work. cpan will tell you this when trying to install Win32::SerialPort.

  This thread hasn't been active for a while ...
  
  I used unload_prop successfully before - thanks Phil.
  
  Now I wanted to back up a running image from a PPDB,
  didn't realize the file size 0 and wiped it ... :-(((
  
  Luckily I had another board.
  Here I get:
  

  PS \Markus\Georg\downloads\Propeller\PropellerTool> .\unload_prop.exe 
  
    Using clock settings:
  
      _clkmode     = XTAL1 + PLL16X
      _xinfreq     = 5000000
  
    Output file: \Markus\Georg\downloads\Propeller\PropellerTool\unload.eeprom.
  
    Connecting to COM6 at 19200 baud.
  
  
    ERROR: Download failed to start correctly or EEPROM header corrupt. Check clock settings.
  
  PS \Markus\Georg\downloads\Propeller\PropellerTool> .\unload_prop.exe 5000000 XTAL1
  
    Using clock settings:
  
      _clkmode     = XTAL1 + PLL16X
      _xinfreq     = 5000000
  
    Output file: \Markus\Georg\downloads\Propeller\PropellerTool\unload.eeprom.
  
    Connecting to COM6 at 19200 baud.
  
  
    ERROR: Download failed to start correctly or EEPROM header corrupt. Check clock settings.
  

  
  The prop is booting and running fine from EEPROM ...
  
  PPDB is original. Crystal says T or I 5.000
  Anything I can do?
  
  thanks

  My Prop OS can save an eeprom to a file on an SD card (FAT26/32). See my signature below for the link
