Question:
How should I connect the MiniProg3 to a DVK board, to bootload over I2C?
Answer:
With VTARG supplied from the DVK:
- Connect the following MiniProg3 pins to the DVK
- VTARG pin -> DVK board VDD (for example 3.3V, i.e. DVK board supply voltage)
- SCLK -> DVK board I2C clock pin
- SDAT -> DVK board I2C data pin
- GND -> DVK board GND
- Program the bootloader project through PSoC Creator
- Open the bootloader host program, and in Port Configuration select Voltage "External". Also select the proper I2C speed and slave address.
- Select a bootloadable .cyacd file and program it
Following is an image showing the Bootloader Host with the correct settings:

Note:
- There is no need for external pull-up resistors as the MiniProg3 already has these resistors (5.6K)
- The MiniProg3 resistors are pulled-up to the VTARG voltage (provided either by the MiniProg3 or the DVK board)
