           Is the verson of component don’t compatible each other? What should I do? My Software is PSoc Creater 2.2,  Need I update the software to PSoc Creater 3.3.

                  Hi sungd   
          Maybe you are using KitProg, PSoC5 version   
          Can you find PSoC3 version?   
          I would be search it and show you later.

                    AN73503, PSoC3 design is contain 2 projects   
            Bootloader and Bootloadable   
            Of course, those must use same device.   
            You have to ensure that.

              I compiled (after updating the project) with Creator 3.0 without any errors.

                Thank guys help. I haven't  a Mini Prog3. My board is CY8CKIT-030 PSoc 3 Development kit. Hope someone can give the mini prog3. And I can update my software to Creator 3.0, Let me try it

                  You do not need a miniprog 3 to program a -030Kit.


                  There are two (2) USB connectors on the board, one is for programming and debugging, the other is connected directly to the PSoC3. I suggest you to have a look into the schematics.


                  When using a bootloader you will have to use the second USB-port to update the chip with the new bootloadable.


                  Sounds a bit complicated  .


                  There is something else I remember (Hopefully some other helper will jump in here) I have in mind that projects using the second USB as bootloader should run at 3.3V but I may be totally wrong with that.
