1. Copy nrf51.cdb to "C:\Keil\UV4"
2. Copy nrf51xxx.flm to "C:\Keil\ARM\Flash"
3. Set the keil project-device to nRF51822(data base : Nordic nRF Series Devices)

This is the logo of Jlink+keil:

It alarm that:“ error ： Flash download failed-"Cotex-M0"”

Is there any problem with "JL2CM3.dll" at C:\Keil\ARM\Segger ? The version I use now is 2.0.0.0 and I try a version of 2.74.0.0 for Cortex-Mx/R4 but failed with error of "cannot load driver 'C:\Keil\ARM\Segger\JL2CM3.dll' "

My OS： windows 8.1

You need to upgrade Keil and/or the Segger tools. According to the log posted, you have version 4.15 of the Segger DLL, which is extremely old and does not support the nRF51. You can get updated Segger tools from Segger.com, but I suspect that you Keil version is also too old, so you may be better off downloading a new Keil version.

I'd recommend you to try the latest Segger tools, 4.80, and Keil at least version 4.74.
