[edit] Loading Bootloader (Once only)

[edit] Hardware Requirement

1. PC with USB port (with Windows)
2. ICD2 Programmer
3. Target Board
4. 5V Power Supply

[edit] Software Requirement

1. MPLAB IDE v7.50: v7.60 is not compatible with our current ICD2 Programmers. There are consistent "Devices cannot be founded" warnings. See manual for details.

[edit] Files

1. dsPicBootloader (bl_$(MODEL).hex).

[edit] Procedure

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 the correct dsPic model
Load Bootloader	Select: File>Import... Select bl_$(MODEL).hex
ICD 2 <-> PC	Plug-in ICD 2 to PC via USB cable
Target <-> ICD 2	Connect six pin cable to target board. Beware of the pin assignments. Only pin 1 - 5 are used. Power-up the target.
ICD 2 <-> PC	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.

[edit] dsPicProgrammer User Guide

dsPicProgrammerUserGuide_V2.0.1

[edit] Hardware Requirement

1. PC (Linux/Windows) with COM Port OR USB-COM converter cable
2. Target Board (with bootloader)
3. 5V Power Supply

[edit] Software Requirement

1. dsPicProgrammer

[edit] Files

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

[edit] Procedure

[edit] Setup COM Port

• Connect your USB-COM converter cable to your computer
• Or Using a real COM PORT

---

[edit] Find out your COM port Number

• Go to Control Panel \ Device Manager

---

• Find out your Device COM Port Number

---

[edit] Get the Dspic Programmer

• Download dsPicProgrammer.zip, from updated directory or svn server
• Unzip the dsPicProgrammer.zip, then you have an unziped file.

---

[edit] Download Firmware

• Save your .hex file(foo.hex) to the folder called firmware.
• Run dsPicProgrammer.bat (Windows) / dsPicProgrammer.sh (linux)
  • Make sure your device is connected through a "Direct RS232 Cable" to PC Serial Port.

---

• Choose a COM port
• Choose a baudrate

115200 is communication speed [in bps]

---

• Choose a .hex file

---

• Press start
• Then press Yes to confirm programming the device

---

• The status during programming

---

• The programming have been completed, press OK the close the message box

---

[edit] Troubleshooting

[edit] Invalid COM Port

• In case of selecting an invalid COM port, you should see the error message:
  gnu.io.NoSuchPortException: Choosing COM Port Error
  
  
  
• Solution: check the COM port ID, or close any programs that are using the COM Port

[edit] 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>
  
  
  
• Solution: check the file path

[edit] 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
  
  
  
• Solution:
  • Copy RXTXcomm.jar to /dsPicProgrammer/rxtx/lib
  • Copy rxtxSerial.dll to /dsPicProgrammer/rxtx/bin (Window)
  • Copy librxtxSerial.so to /dsPicProgrammer/rxtx/bin (Linux)

[edit] Missing JAVA

• In case of missing JAVA JDK or JRE, an error message will be prompted.
• Solution:
  • Copy the contents under directory C:/Program Files/Java/jre$(VERSION)/ to /dsPicProgrammer/jre
