Problem programming nRF52 DK

[Gauti]

Hello,

I received the nRF52 DK and tried setting it up as described in infocenter-->nRF52 Series --> Get Started.

I have the following installed: Keil uVision5

Error: Load "\nRF\nRF52_SDK_0.9.1_3639cc9\examples\peripheral\blinky\pca10036\blank\arm5_no_packs\_build\nrf52832_xxaa.axf" Error: Flash Download failed - Target DLL has been cancelled Flash Load finished at

Working on Windows 7; used nRFTools 7.6.0 installer successfully; Installed nRFgo Studio.

I am able to see the JLINK drive

After doing all these setup I am not able to connect to nRF52832 through USB and flash the blinky program.

I am not sure if i am missing anything here. I would appreciate if anyone would help me out in setting this up.

Thanks a lot for your input. I did try installing latest J-Link drivers but it did not help. The problem was with windows drivers. I had to clean the registry, uninstall and re-install everything to make it work.

It would have been hard to guess that something went wrong in the registry. Glad that you figured it out.
