2. Application hex file (e.g. app.hex)

Loading Bootloader (Once only)

Loading Bootloader

Step	Remarks
Install MPLAB IDE	Do NOT connect ICD 2 (via USB) to PC Execute MPLAB vX.XX Install.exe
Install USB Driver	Follow the instruction in (C:\Program Files\Microchip\MPLAB IDE\ICD2\Drivers\Ddicd2.htm)
Select Target Chip	Run MPLAB IDE on PC Select: Configure>Select Devices... Choose dsPIC30F5011
Target <-> ICD 2	Use six pin cable. Beware of the pin assignments. Only pin 1 - 5 should be used. Place Jumper on target board (if any). The Jumper connects target Vcc to ICD 2. Do NOT power-up the target.
ICD 2 <-> PC	Plug-in ICD 2 to PC via USB cable Power-up the target. Select: Programmer>Select Programmer>MPLAB ICD 2 If this is the first time the ICD 2 is connected to PC, MPLAB IDE will automatically download the required OS to ICD 2, wait until it has finished If you have not connected and powered up the target, you might see Warnings on invalid device IDs, and/or running self tests. See results of self test if necessary: Programmer>Settings, Status Tab. Refer to ICD2 User's Guide Chapter 7.
Load Bootloader	Select: File>Import... Select bl_5011.hex
Start Programming	Select: Programmer>Program
Finishing	Power-down the Taget Select: Programmer>Select Programmer>None Unplug USB cable

Loading Firmware

Java Environment Setup

• Download and install the latest JDK or JRE
  • Available from Sun Microsystems (e.g. JDK 6 Update 3)
    
    
• Download and Extract RXTX Driver
  • Available from RXTX
  • File: rxtx-2.1-7-bins-r2.zip (Final)
  • Extract the files using software such as WinRAR
    
    
• Copy RXTXcomm.jar to
  • For Windows users, C:\Program Files\Java\X\lib\ext (under the latest jre, e.g. X = jre1.6.0_03)
  • For Linux users, /usr/lib/jvm/java-version/jre/lib/ext
    
    
• Copy rxtxSerial.dll/librxtxSerial.so to
  • For Windows users, C:\Program Files\Java\X\bin (under the lastest jre, e.g. X = jre1.6.0_03)
  • For Linux users, /usr/lib/jvm/java-version/jre/lib/[machine type] (i386 for instance)
    
    
• Download dsPicProgrammer
  • Available from here
  • directly download this package
  • Expand the latest tag under dsPicProgrammer
  • File: dsPicProgrammer.jar
    
    
  • Save the file (dsPicProgrammer.jar) and your hex file (foo.hex) to your local directory (e.g. C:\dsPicProgrammer\)
    
    

Download Firmware

• Start a Command Prompt
  • Start -> Run
    File:2 1 run.JPG
    
  • Enter cmd
    File:2 2 cmd.JPG
    
• Run dsPicProgrammer
  • Make sure your device is connected through a "Direct RS232 Cable" to PC Serial Port.
  • Change to the directory where dsPicProgrammer.jar is located and run the command:
    • [path/to/java/]java -Djava.library.path=[path/to/rxtxlib] -jar dsPicProgrammer.jar COM1 57600 foo.hex
      • for example, jre\bin\java -Djava.library.path=.\rxtx\bin -jar dspicProgrammer.jar COM1 57600 foo.hex
    • Or directly using dsPicProgrammer.bat COM1 57600 foo.hex(Windows)
    • java -jar dsPicProgrammer.jar /dev/ttyS0 57600 foo.hex (Linux)

where COM1 is your COM Port ID

57600 is communication speed [in bps]

foo.hex is your firmware new file

• • When the program prompt you for an input, press y:
    File:2 4 prompt.JPG
    
  • If communication can be established, you should see something like this:
    
    
  • Wait until programming is completed.
    
    
  • after all completed, power OFF your device, then power ON again, enjoy your new updated.

Troubleshooting

Missing firmware file

• In case of selecting a firmware file that does not exist, you should see the error message:
  java.io.FileNotFoundException: foo1.hex <The system cannot find the file specified>
  
  

Missing RXTX driver

• In case of missing the RXTX driver, you should see the error message:
  Exception in thread “main” java.lang.NoClassDefFoundError: gnu/io/UnsupportedCommOperationException
