i am using wt51822 s4at chip and trying to program it with st-link and when i try to run simple blinky example from nrf51 sdk it gives some error my flash settings are in image

Here is my configuration. It works well.

• Connect device and debugger (target board have to be powered.)

• Select debug adapter

• Select SW(SWD) as port and check device on connection

• Check programming algorithm and address range

If you are still faced with errors, you should adjust maximum clock speed.
