Hi,

Please describe what exact firmware you are debugging. 
Where do you see the error, and what inside error_info. At which step do you get the error.

i am just debugging buttonless ble dfu. and im getting error when debug of program. im getting error in

APP_ERROR_CHECK(err_code);    --->>> here i got runtime error

Please list the step you used for testing. Please try to test the bootloader without the buttonless dfu application first. Made sure you can use the bootloader correctly. 

When you see an error with APP_ERROR_CHECK please check the err_code and check the function that return the err_code to see why it occurred. 

Note that you can set a breakpoint to check for error code, but you can't step the code lines to debug through the code in an application that uses softdevice because the softdevice doesn't work any more after you stopped in a breakpoint.
