If its not getting sufficient power from st-link you will get ths kind of errors. Take a multi meter and measure voltage across Vcc and ground (For nrf51822 Ideal votage will be 3.3v )

Yes, each Nucleo board has an on-board St-Link. IMO the error is not due to your hardware... You could also buy an nRF52 dev kit which comes with an on-board J-Link (Segger tools).

Hi, metch. No luck for both. I am think to use another board to try. my.element14.com/.../2517896 What do you think about this one? would it work? it support st link v2-1

Which OS do you use ? You use OpenOCD in console mode ? Which command do you use to detect the nRF51 chip ? They are many tutorials to program the nRF51 with OpenOCD and an STLink probe, see these links for instance:

You probably have a driver or connection issue.

HI, metch. Thanks for the guide. Pardon me for not stating clearly. Yes, i connected the SWDIO(P2 pin5) and SWDCLK(P2 pin6), not the P0.17 and P0.19. However, the openocd still couldn't connect to nrf51822 board. Any more idea? Thanks in advance.

You can use ST-Link probes to program the nRF51 using OpenOCD. You probably have a wrong connection to the nRF51 board. You have to connect the following 4 lines: SWDIO, SWCLK, VCC and GND.

Have a look at the schematic of the Core51822 board:

You must connect SWDIO and SWDCLK and not P0.17 and P0.19. The full schematic is available here: www.waveshare.com/.../Core51822-Schematic.pdf

It is hard to help you. Please provide more details on the environment you use (OS, IDE, tools, etc.). The article you mention use openocd 0.8.0. This is an old version, you should use openocd 0.9.0 or 0.10.0-dev.

They are many posts about OpenOCD and nrf51 programming, please have a look at these posts.
