Hello friends,

I am trying to flash a nrf51 dk with keil5. When I try to flash it with a multilink universal I get this error:

My settings are the following:

Thank you.

Hi, if you are using the nRF51 DK use the on-board JLink programmer. The examples are configured to use this by default. You might have to click on settings and select the correct JLink serial.

I have no problem using the on-board JLink, but on my final project I will have only the NRF51422, so I would like to program it via pe&micro

How are you powering the DK? If you power the DK over the USB port and connect the programmer to the "debug in" port the on-board programmer will probably hold the SWD lines down. You should try to power the DK from an external source on P21 or use a battery, leaving the USB unplugged. Then the JLink will not be powered up.

Hello,

I was powering the nrf51dk via USB, I tried powering 3v3 in P21 with no sucess, same error.

I uploaded higher resolution captures.

Thank you

I suggest you contact PEmicro support. I don't have the Multilink debugger here, so I'm afraid I can't help you that much.
