problem in using j-link edu for debugging the stm32f4 discovery board

dear segger team,

I bought one segger j-link edu from mouser electronics just couple of weeks back and trying to check it by connecting it to my discovery board.

I used the following link in order to interface the j-link with stm32f0 discovery board :…overyBoards.pdf

information on page 14 has been used and I made the connections accordingly, but its not able to program and debug my board.

also there is no 5 V output from pin 19 as checked from multimeter.

This time I used to program my STM32F0 Discovery Board with the Jlink Edu using the Keil IDE and simple blinky program.

but it outputs following message in the Build output window of Keil IDE:
