nRF51 DK, Keil cannot build an example

[teddy.c]

I just would like to test my new nRF51 DK using the SDK V9. However, I could't build the "blinky_blank_pca10028". It always shows the following error.

Error: *** Project 'blinky_blank_pca10028', Target 'nrf51422_xxac', Device 'Nordic Semiconductor::nRF51422_xxAC' is not supported by Toolchain ! ***.

The nRF51 DK can be flashed by using nRFgo Studio.

I have found only one solution, from this forum, that I have to create an ARM-M0-target project. However, I haven't tried this solution yet.

Could you please give me any suggestion? How could I solve this problem? Thank you very much in advance for your information.

Keil version: V5.16

It seems that you missed MDK installation: Go to this page: www.nordicsemi.com/.../nRF51822 And from downloads tab select MDK for your compiler.

Thank for your sugeestion. Actually, I have already installed the MDK. But the error still exists.

I have also found the Nordic Pack in the Keil folder.
