How to use nRF52832 with J-link in KEIL?

[roger.k]

Hi. I just started development with nRF52840.

Press "Setting' button, it shows me "The selected device "NRF52840_XXAA" is unknown .......

And actually it doesn't have nRF52840 device as below.

Then I can see J-link version is V5.10h.

So I installed newest version of J-link(V6.4.0).

But it isn't changed.

How can I install nRF52840 on my Keil compiler?

I need your help.

Hi,

You can find the tools you need from here:

In this case I suspect you have not download and installed the latest nRF5x tools, and make sure SEGGER j-link update your software (example from my screen):

Best regards,

Dear Kenneth. Thank you very muhc for your help.

I can't see Keil MDK as below.

So I downloaded and install MDK as below.

Even after installing MDK-ARM, I can't see Keil MDK-ARM on my J-Link updater.

How can I add this to mine?

I'm sure I installed nRF5x tools, because I can use 'mergehex command' and 'nrfutil pkg generate command'.

My Keil version is MDK-ARM V5.21a released at 8/17/2016. Could it be the problem?

Seems like SEGGER J-Link Updater didn't recognize your Keil installation? It's missing from your screenshot. 

Best regards,
Kenneth
