Hi Cadambi,

Have you make sure the debug option was configured properly ? Please follow the setting in the attached image.

Regarding blinky example, did you mean LD3 (not LED3 ? ) was blinking when you program ? Did it blink after programming, when the device is running ?

Have you tried any other examples ?

Hi , I am having the nrf51422 Evaluation kit and i am trying to run the blinky project. The chip marking is n51422 QFAACO 1302AC. The build works fine and here is the build message :

Build target 'nrf51422' creating preprocessor file for main.c... compiling main.c... linking... Program Size: Code=488 RO-data=208 RW-data=0 ZI-data=4192
"._build\blinky_arm.axf" - 0 Error(s), 0 Warning(s).

But when i try to load it from Keil ARM , the 'LED 3' blinks. Could you please tell me why it blinks and what changes needed to be made to make the LED 0 and LED 1 to blink as per the example blinky project?

Here is the output from Keil after i try to execute the 'Load' :

Load "C:\keil\ARM\Device\Nordic\nrf51422\Board\pca10003\blinky_example\arm\_build\blinky_arm.AXF" Set JLink Project File to "C:\keil\ARM\Device\Nordic\nrf51422\Board\pca10003\blinky_example\arm\JLinkSettings.ini"
