Hi,

I own a Nordic nRF51822 Development Kit and I'm trying to connect to the PCA10005 via J-Link LITE Cortex M.

JLinkExe connects to the J-Link Hardware, connected via USB. But it shows me a VTarget of 0.0 V.

What did I miss before starting JLinkExe?
I already tried to set a device, speed, ...

Shouldn't it work out of the box, when my nRF51822 is connected to the J-Link hardware?

regards,
nRF51822

here some console output:

$ JLinkExe -device nRF51822 -speed 1000

Hi Alex,

I want to apologize for my late answer and thank you for that hint.
It was really the missing power supply. I was hoping that the j-link is providing the power supply.

On the other hand, I had some trouble trying to flash the PC1000 (USB powered).

In other forums, I could read about a buggy J-Link version 4.82, which should be fixed in 4.83, but I had no success with 8.84.
Now I'm using 4.85d and it's working.

Maybe this is helping someone else later here.

Thanks für your help.

regards,
nRF51822
