Erase all failed: Unable to find or open the JLinkARM dll

[Tomislav]

Hello,

I have a nRF51 DK (PCA10028) and I managed to programm an onboard nRF51422 SoC. Now, I'm trying to programm a nRF51822 on a costum board (WT51822-S2). I wanna try to programm it with a onboard JLink by connecting SWDIO - SWDIO, SWCLK - SWCLK, VDD - VTG - VDD, GND - GND from a P20 port on PCA10028 to WT51822-S2. After successful connection, I'm trying to erase it the SoC, unsuccesfully. I get an Error saying: "Erase all field: Unable to find or open the JLink ARM dll"

I'm using Windows 7 64 bit. Installed all drivers and everything....

Please help, Im new to nRFs Thanks!

I found out yesterday that I did not connect the GND from the PCA10028 to the GND on the nRF51822, because there is no GND pin on the debugging port P20. There is only GND_DETECT, which is not ground! So, by connecting grounds, I solved the problem :) How silly of me!
