Yes you should connect to SPI lines as displayed in application and use external power supply (I can not see VCC line from flash memory on debug connector). When you connect external power supply (e.g. ac adapter from notebook) just wait 2-3 minutes before programming because it may be during bootloader init process and it will be conflict at spi bus.
