Thank you. I seccessed by changing the clock source to RC oscillator.

Also all GPIO settings (buttons, LEDs, SPI, TWI, UART...) should be checked if used by the example, it will most probably differ.

No, the SDK examples should work on any board. Just be aware that the default setting for the LFCLK in the SDK examples is "external 32 kHz crystal". If your board doesn't have an external 32 kHz crystal, the LFCLK source should be set to the internal RC oscillator.

Thank you. I successed the flash load. nRF go studio recognize nRF51822, not nRF51422 on board. but nRF51822 module does not work when I flash ble_uart service example(SDK 11.0.0) and softdevice 2.0.0. are these examples dedicated to DK board?

Hi, have you searched the forum? i believe there must be dozen of Q&As on the same topic (how to flash nRF5x on custom board with nRF5 DK's ports P20 or P19), this is just one example (follow the links in bottom section, there is even explanation why you don't need to "cut" internal nRF5 chip on the DK board when you want to flash the external).
